No. 14/356,988, filed May 8, 2014, entitled “Combination Animal Repellents,” which is a 35 U.S.C. §371 U.S. National Stage Entry of International Application No. PCT/US2012/061817 filed Oct. 25, 2012, entitled “Combination Animal Repellents,” which claims the benefit of priority of U.S. Provisional Patent Application No. 61/557,985 filed on Nov. 10, 2011, entitled “Combination Animal Repellents,” and U.S. Provisional Patent Application No. 61/638,590 filed on Apr. 26, 2012, entitled “Combination Animal Repellents,” the contents of each of which are hereby incorporated by reference in their entirety.


FIELD OF THE INVENTION
The invention relates to an animal and/or insect repellent and, in particular, to broad spectrum repellent compositions which will repel a variety of pests and which can be applied to a wide range of surfaces and substrates. Methods of use are also disclosed.
BACKGROUND OF THE INVENTION
The encroachment of human habitation on heretofore rural areas has exacerbated existing problems of pest control. In recent years suburban backyards and public green spaces have been invaded by exploding deer populations and fowl who take up residence on ponds and in public areas near water fouling the surface or surrounding land area. Insect pests and rodents are also becoming more prevalent in suburban, urban and rural areas. Further, with the changes in climate and the expanding human habitation into rural areas livestock and household pets have become increased targets for predators.
Synthetic and often toxic chemical control means have long been used to manage pest and animal movement and populations. However, with increasing public awareness of health issues regarding the impact on humans and the environment exposed to such chemical compounds, much effort has been expended in the identification of more benign and natural control measures.
To this end, legislative steps have been taken to categorize certain natural compounds as safe for use and hence exempt from certain government regulations. Such active ingredients qualifying for Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) exemption include castor oil (U.S.P. or equivalent), linseed oil, cedar oil, malic acid, cinnamon and cinnamon oil, mint and mint oil, citric acid, peppermint and peppermint oil, citronella and citronella oil, 2-Phenethyl propionate (2-phenylethyl propionate), cloves and clove oil, potassium sorbate, corn gluten meal, putrescent whole egg solids, corn oil, rosemary and rosemary oil, cottonseed oil, sesame (includes ground sesame plant) and sesame oil, dried blood, sodium chloride (common salt), eugenol, sodium lauryl sulfate, garlic and garlic oil, soybean oil, geraniol, thyme and thyme oil, geranium oil, white pepper, sodium lauryl sulfate, zinc metal strips (consisting solely of zinc metal and impurities) and lemongrass oil.
Despite the strong incentive to develop natural and safe pesticides and animal repellents, there remains a long-felt need for compositions that are as effective (or more effective) than the chemical toxins currently in use to mitigate the economic and health impact of pests on humans.
SUMMARY OF THE INVENTION
The present invention provides compositions for use as single- or multi-species (broad spectrum) repellent that alters the movement of animals and/or insects.

DETAILED DESCRIPTION OF THE INVENTION
The present invention provides compositions for use as single- or multi-species (broad spectrum) repellent that alters the movement of animals and/or insects. As such, the present invention is directed to geraniol oil, rosemary oil, putrescent whole egg solids and/or other FIFRA active ingredient based combination compositions for use as single- or multi-species (broad spectrum) animal and/or insect repellents. In combination with the pest management systems described herein, the invention also embraces the use of attractants. Further aspects of the invention include the application of the formulations of the invention by contacting or impregnation to one or more substrates or surfaces. The formulations of the present invention provide further advantages in that most comprise only natural ingredients or ingredients not requiring EPA approval making them useful for application by homeowners and non-licensed applicators as well as for professional use.
DEFINITIONS
A “repellent” as used herein is any composition or formulation that makes unattractive to pests a habitat, food source or other site ordinarily sought or frequented. The term “pest” is intended to include living organisms that occur where they are not wanted or that cause damage to crops or food or turf or humans or other animals. Examples of pests include, but are not limited to, insects, mice, squirrels, reptiles, rodents and other animals (e.g., predators, household pets and wild life), unwanted plants (weeds), fungi, microorganisms such as bacteria and viruses, and prions.
An “attractant” as used herein is any composition or formulation that makes attractive to pests a habitat, food source or other site which may be frequented or traversed by the pests.
“Alter the movement” as used herein refers to the ability of a formulation to change the mobility or direction of a pest (an animal and/or insect). For example, a repellent formulation applied to a surface may “alter the movement” of such insects by making a region of application near the surface unattractive to the insects and prevent the insects from approaching the surface.
“Predators” as used herein refers to an organism that preys on other organisms. Predators are usually animals that live by preying on other organisms for food. A non-limiting list of predators include lions, tigers, bears, bobcats, lynx, coyotes, wolves, wild and domestic dogs, foxes, hogs, mountain lions, weasels, mink, snakes, raccoons, skunks, opossums, domestic cats, and badgers. “Prey” as used herein refers to an organism that is hunted and killed by another organism for food. For example, many predators may hunt and eventually kill their prey such as, but not limited to, lions preying upon a buffalo, coyotes preying on livestock, and foxes preying on chickens.
Specifically, it has been discovered that the combination of one or more essential oils with one or more herb oils provide superior animal and/or insect repellent properties. As such, the components of the repellent compositions of the present invention function in a synergistic manner to provide multiple layers of repulsion. The repulsive effect is broad spectrum with regard to the number of animal and/or insect species repelled thus avoiding the necessity of applying multiple compositions to repel various animal pests, hence the compositions and their formulations broad spectrum repellents. “Broad spectrum,” as used in the context of a repellent, means that the repellent possesses activity against multiple species of animals, insects and/or organisms.
As used herein, an “essential oil” is any hydrophobic liquid containing volatile aromatic compounds from plants. They are also known as volatile or ethereal oils, or simply as the “oil of” the plant material from which they were extracted, such as oil of clove. The term “essential” indicates that the oil carries distinctive scent (essence) of the plant. Essential oils are typically extracted by distillation and hence may be concentrated. Other processes include expression and solvent extraction. Essential oils may include sub-categories of oils such as “herb oils” and “mint oils”. Among essential oils are eucalyptus oil and castor oil. The essential oils also include mint oil, jasmine oil, camphor oil, hinoki oil, tohi oil, pomegranate oil, turpentine oil, cinnamon oil, bergamot oil, mandarin oil, calamus oil, pine oil, lavender oil, bay oil, clove oil, hiba oil, rose oil, lemon oil, thyme oil, peppermint oil, rose oil, sage oil, menthol, cineole, eugenol, citral, citronellal, borneol, linalool, geraniol, camphor, thymol, spilanthole, pinene, limonene, and terpene compounds.
The term “herb oil” as used herein refers to any of the oils derived from herbs. An “herb” is a plant lacking a permanent woody stem. Among the preferred herb oils are mint and geranium oils with geraniol oil being most preferred.
Repellent compositions of the present invention may comprise at least one FIFRA active ingredient such as, but not limited to, geraniol oil, rosemary oil, mint, mint oil, cinnamon oil, clove oil, eugenol, putrescent whole egg solids, castor oil, sodium lauryl sulfate, sodium chloride, potassium sorbate and one inert ingredient such as, but not limited to, xanthan gum, sodium sulfate, kaolin (clay) and water.
The term “FIFRA active ingredient” refers to the active ingredients exempted under 25(b) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Examples of FIFRA active ingredients include castor oil (U.S.P. or equivalent), linseed oil, cedar oil, malic acid, cinnamon and cinnamon oil, mint and mint oil, citric acid, peppermint and peppermint oil, citronella and citronella oil, 2-Phenethyl propionate (2-phenylethyl propionate), cloves and clove oil, potassium sorbate, corn gluten meal, putrescent whole egg solids, corn oil, rosemary and rosemary oil, cottonseed oil, sesame (includes ground sesame plant) and sesame oil, dried blood, sodium chloride (common salt), eugenol, sodium lauryl sulfate, garlic and garlic oil, soybean oil, geraniol, thyme and thyme oil, geranium oil, white pepper, sodium lauryl sulfate, zinc metal strips (consisting solely of zinc metal and impurities) and lemongrass oil.
The term “inert ingredient” refers to the listing of inert ingredients approved for nonfood use. Examples of inert ingredients include, but are not limited to, xanthan gum, sodium sulfate, kaolin (clay) and water.
The repellent compositions may optionally comprise further components including, but not limited to, carriers, thickeners, surface-active agents, preservatives, aromatics, deodorizers, antibacterial agents, antifungal agents, antimicrobial agents, biocide agents, sunscreen active and one or more of several types of adjuvant including, but not limited to, wetting agents, spreading agents, sticking agents, foam retardants, buffers and acidifiers. The term “antibacterial agents” refers to substances which may destroy or inhibit the growth of bacteria; “antifungal agents” refers to substances which may destroy or inhibit the growth of fungi; “antimicrobial agents” refers to substance which may kill or inhibit the growth of microorganisms and “biocide agents” refers to chemical substances or microorganisms which may be capable of destroying living organisms. As used herein, “sunscreen active” is an additive that may absorb or reflect some of the ultraviolet radiation from a surface exposed to sunlight. The repellent compositions of the present invention may also be formulated in a combination with commercially available pesticides or insecticides (natural or synthetic).
The repellent properties of the compositions of the present invention qualify them as pesticides. According to the Environmental Protection Agency (EPA) and as used herein a “pesticide” is any substance or mixture of substances intended for: preventing, destroying, repelling, or mitigating any pest. They also include any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant.
Typically, the repellent compositions are prepared as a concentrate and diluted to application strength or admixed with the appropriate particulate matter when used.
Concentrates may be diluted with water or suitable solvent at the time of use or it may be in ready-to-use form whereby the formulation requires no further manipulation before use. The term “concentrate” is used herein to describe a repellent composition or formulation which is in condensed form. A concentrate of the present invention is not necessarily without the presence of any diluent, e.g. water. Hence, a concentrate may be in liquid, solid, or gel form. It may be impregnated in or mixed with another substance which allows for distribution into the environment such as in a humidifier, diffuser, candle or air freshener.
For all components of the repellent compositions or their formulations, values in increments of the smallest measured value (e.g., for geraniol oil, 0.05%) are embraced within the ranges specified. For example, the range from 0.05% to 30% embraces the weight percentages of 0.05%, 0.10%, 0.15% . . . 29.9%, 29.95% and 30%.
Further, as used throughout the specification the term “about” is defined as plus or minus 10% of the stated value.
As used herein, the term “bait” as it relates to pest is any substance or composition in any form which lures or entices, whether chemically or physically (such as a visual cue), a pest. Baits include, but are not limited to, those made by Raid, Term, Combat, Jensen, Hot Shot, Woodstream, SC Johnson, Advance, MaxForce, or any commercially available bait or combination thereof and the like. A “bait” may also be an attractant.
As used herein, a “trap” or “bait box” means any container or structure which may contain a bait, attractant or repellent and which is capable of containing one or more pests.
Units of measure used herein embrace both standard units and metric units. It is to be understood that where repellent or attractant compositions are measured, formulated or packaged as liquids, the units may be in increments of ounces, cups, pints, quarts, gallons, barrels, or portions thereof. They may also be in increments of milliliters, cubic centimeters, deciliters, liters, cubic meter or portions thereof.
It is to be understood that where repellent or attractant compositions are measured, formulated or packaged as solids, the units may be in increments of ounces, pounds, tons, or portions thereof. They may also be in increments of milligrams, grams, kilograms, metric tons or portions thereof.
Coverage, as it relates to the effectiveness of the repellent or attractant radius of the devices of the invention, may be expressed in inches, feet, square feet, yards, square yards, acres, square acres, or portions thereof. They may also be in increments of millimeters, square millimeters, centimeters, square centimeters, meters, square meters, hectares, kilometers, square kilometers or portions thereof. Conversion between the standard and metric systems is readily understood in the art and particularly by those of skill in the art. Therefore, the present invention which teaches formulations in weight percent and ratios for dilution of concentrate are not limited to any particular system of measurement. For example, while the instant examples may describe the use of a single system, the present invention is just as clear on the formulation of a quart of repellent composition as a liter of repellent composition.
Geraniol Oil
In one embodiment, the repellent compositions and formulations thereof may contain geraniol oil. While some of the compositions of the present invention are referred to as “geraniol-based” this designation is not intended to imply any specific quantity or proportion of geraniol. It is merely to convey that the compositions contain geraniol.
Geraniol, (3,7-dimethyl-2,6-octadien-1-ol; CAS Reg. No. 106-24-1; C10H18O) is a clear to pale yellow monoterpenoid alcohol which exists as an oily liquid. It is insoluble in water, but soluble in most common organic solvents. It has a rose-like odor, for which it is commonly used in perfumes. It is the primary part of oil-of-rose and palmarosa oil. It also occurs in small quantities in Geranium, Lemon, Citronella, and many other essential oils. Geraniol may be derived directly from geranium plants engineered to produce larger amounts of geraniol or from lemon grass or other herbs. It is typically extracted from geranium oil through a refining process.
While geraniol is used in insect repellants or deterrents to repel mosquitoes, house flies, stable flies, horn flies, cockroaches, fire ants, fleas, gnats, dog ticks, lone star ticks, no-see-ums, mite, crickets, earwigs, silverfish and lice, it is not known to have bird or non-insect repellant functionalities.
Surprisingly, it has been discovered that geraniol oil, in combination with castor oil, and mint does indeed have both bird and non-insect repellent properties as well as the killing of some organisms including scales. Such combinations are detailed in published co-pending application International Application PCT/US2011/031901 filed Apr. 11, 2011, the contents of which are incorporated herein by reference in their entirety.
According to the present invention, geraniol oil may be present in the compositions of the present invention from about 0.05% by weight to about 30% by weight, but may be higher in concentrated formulations. In one embodiment, geraniol is present in an amount from 3-25% by weight. In a further embodiment it is present in an amount by weight of from 5-20%. In addition, geraniol oil may be present in amounts between or bounded by those recited herein. For example, the weight percentages 0.05-1%, 2-3%, 20-30%, 3-10%, 15-25%, 5-10%, and 15-20% are within the scope of the invention.
Rosemary Oil
In one embodiment, the repellent compositions and formulations of the present invention may contain rosemary oil. While some of the compositions of the present invention are referred to as “rosemary oil-based” this designation is not intended to imply any specific quantity or proportion of rosemary oil but it is merely to convey that all of the compositions contain rosemary oil.
Surprisingly, it has been discovered that rosemary oil (CAS Reg. No. 8000-25-7), in combination with castor oil, and mint does have bird, insect and animal repellent properties. Such combinations are detailed in published co-pending application International Application PCT/US2008/072993 filed Aug. 13, 2008 and U.S. patent application Ser. No. 13/058,424 filed Apr. 7, 2011 the contents of which are incorporated herein by reference in their entirety.
According to the present invention, rosemary oil, when present, may be present in the compositions of the present invention from about 0.05% by weight to about 30% by weight, but may be higher in concentrated formulations. In one embodiment, rosemary oil is present in an amount from 3-25% by weight. In a further embodiment it is present in an amount by weight of from 5-20%. In addition, rosemary oil may be present in amounts between or bounded by those recited herein. For example, the weight percentages 0.05-1%, 2-3%, 20-30%, 3-10%, 15-25%, 5-10%, and 15-20% are within the scope of the invention.
Putrescent Whole Egg Solid
In one embodiment, the repellent compositions and formulations thereof may contain putrescent whole egg solid. While some of the compositions of the present invention are referred to as “putrescent whole egg solid-based” this designation is not intended to imply any specific quantity or proportion of putrescent whole egg solid. It is merely to convey that the compositions may contain putrescent whole egg solid.
Putrescent whole egg solids (CAS Reg. No. 51609-52-0) such as, but not limited to, inedible egg powder, dried whole egg, or powdered inedible egg solids), may be produced from eggs which the USDA has declared inedible for human consumption due to cracked shells, excessive blood spots or other imperfections not conforming to standards set for food use. They may be produced by centrifuging whole eggs, which have been cracked or broken, to separate the shell from the liquid egg. The liquid egg may then be pumped through a strainer to remove foreign material (e.g., shell pieces) then placed in a holding tank or passed through a pasteurizer, cooled, spray dried and packaged for storage. The powdered eggs may be hydrated at the time of use which initiates the decaying process.
According to the present invention, putrescent whole egg solid may be present in the repellent compositions from about 0.01% by weight to about 15% by weight. In one embodiment, putrescent whole egg solids are present in an amount from 0.1-13% by weight. In a further embodiment, it is present in an amount by weight from 0.15-10%. In addition, putrescent whole egg solids may be present in amounts between or bounded by those recited herein. For example, the weight percentages 0.05-1%, 2-3%, 1-10%, 3-10%, 10-15%, and 5-10% are within the scope of the invention.
Cinnamon Oil
In one embodiment, the repellent compositions and formulations of the present invention may contain cinnamon oil. Cinnamon oil (CAS Reg.

In formulations which are granular or substantially dry in nature, SLS may not be necessary.
Kaolin (Clay)
In its natural state kaolin is a white, soft powder consisting principally of the mineral kaolinite. It is commonly used in the manufacture of china (porcelain), paper, rubber and paints. When mixed with water in the range of 20 to 35 percent, it becomes plastic (i.e., it can be molded under pressure), and the shape is retained after the pressure is removed. With larger percentages of water, the kaolin forms a slurry, or watery (aqueous) suspension as kaolin is insoluble in water.
Modified kaolin is used in industry as a physical barrier-type crop protectant. In these formulations, it is sprayed on as a slurry, whereby the water evaporates, leaving a powdery film on the surfaces of leaves, stems, and fruit. The film acts to protect plants and deter insects. However, to be effective, the film must coat all parts of the fruit or plant.
In one embodiment of the present invention, kaolin may be added to the repellent compositions to improve adherence properties. It is not necessary that the repellent compositions containing kaolin described herein entirely coat or cover all parts of the surfaces or substrates treated in order to be effective repellents.
According to the present invention kaolin, when used, may be present in the compositions of the present invention from about 0.01% by weight to about 10% by weight. In one embodiment, kaolin may be present in an amount from about 0.01%-5% by weight. In another embodiment, kaolin may be present in an amount from about 0.03%-5% by weight. In a further embodiment it may be present in an amount by weight of from about 0.05-2%. In addition, kaolin may be present in amounts between or bounded by those recited herein. For example, the weight percentages 0.01-5%, 5-10%, 0.03-2%, 2-5%, 0.05-1%, and 1-2% are within the scope of the invention.

According to some embodiments, granular repellent compositions are used to repel rodents from outdoor areas including, but not limited to yards, trails, gardens, fields or forests. In one embodiments, granular repellent compositions are placed in and around pest habitats (e.g., a rodent hole or borough).
Carriers
In addition to the components listed in the Tables above, the repellent compositions and formulations of the present invention may contain one or more carriers or carrier vehicles. As used herein a “carrier” is a substance that transmits, serves, or aids in transmission or acts as the medium for transmission. Carriers may be liquid or solid. They are most often inert but may be active ingredients.
Examples of conventional carrier vehicles include, but are not limited to, aerosol propellants which are gaseous at normal temperatures and pressures, such as freon; inert dispersible liquid diluent carriers, including inert organic solvents, such as aromatic hydrocarbons (e.g. benzene, toluene, xylene, alkyl naphthalenes, etc.), halogenated especially chlorinated, aromatic hydrocarbons (e.g. chloro-benzenes, etc.), cycloalkanes, (e.g. cyclohexane, etc.), paraffins (e.g. petroleum or mineral oil fractions), chlorinated aliphatic hydrocarbons (e.g. methylene chloride, chloroethylenes, etc.), alcohols (e.g. methanol, ethanol, propanol, butanol, glycol, etc.) as well as ethers and esters thereof (e.g. glycol monomethyl ether, etc.), amines (e.g. ethanolamine, etc.), amides (e.g. dimethyl formamide etc.), sulfoxides (e.g. dimethyl sulfoxide, etc.), acetonitrile, ketones (e.g. acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, etc.), and/or water; as well as inert dispersible finely divided solid carriers such as ground natural minerals (e.g., vermiculite, alumina, silica, chalk, i.e. calcium carbonate, talc, attapulgite, montmorillonite, kieselguhr, etc.) and ground synthetic minerals (e.g. highly dispersed silicic acid, silicates, e.g., alkali silicates, etc.).
The repellent compositions of the present invention may be admixtures with finely divided solids such as talc, attapulgite clay, kieselguhr, pyrophyllite, chalk, diatomaceous earth, vermiculite, calcium phosphates, calcium and magnesium carbonates, sulfur, flours, and other organic and inorganic solids which act as carriers. These finely divided solids, or dusts, preferably have an average particle size of less than about 50 microns. A typical dust formulation useful for controlling pests contains 1 part of pesticidal composition and 99 parts of diatomaceous earth or vermiculite. Granules may comprise porous or nonporous particles. The granule particles are relatively large, a diameter of about 400-2500 microns typically. The particles are either impregnated or coated with the inventive repellent compositions from solution. Granules generally contain 0.05-15%, preferably 0.5-5%, active ingredient as the pesticidally-effective amount. Thus, the repellent compositions of the present invention can be formulated with any of the following solid carriers or diluents such as bentonite, fullers earth, ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, vermiculite, and ground synthetic minerals, such as highly-dispersed silicic acid, alumina and silicates, crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic materials such as sawdust, coconut shells, corn cobs, tobacco stalks and other natural cast off products that may or may not be a by-product of manufacturing or harvest such as walnut or nut shells or egg shells.
Surface-Active Agents
It may also be necessary to include one or more surface active agents. Surface-active agents, (i.e., conventional carrier vehicle assistants) that may be employed with the present invention include, without limitation, emulsifying agents, such as non-ionic and/or anionic emulsifying agents (e.g. polyethylene oxide esters of fatty acids, polyethylene oxide ethers of fatty alcohols, alkyl sulfates, alkyl sulfonates, aryl sulfonates, albumin hydrolyzates, and especially alkyl arylpolyglycol ethers, magnesium stearate, sodium oleate, etc.); and/or dispersing agents such as lignin, sulfite waste liquors, methyl cellulose, etc.
Thickeners
One or more thickeners or thickening agents may be added to the compositions of the present invention. “Thickeners” are substances which, when added to a mixture (aqueous or otherwise), increase its viscosity without substantially modifying its other properties. Thickeners may be used to ensure uniform consistency. A starch, thickener, or gelling agent may also be used to alter the consistence of the repellent compositions of the present invention. Agar, corn starch, potato starch and guar gum or the like, may be used. These agents can also be added to keep the ingredients in suspension. Typically thickeners are added at about 0.1 to 5% of the total composition.
Preservatives
Preservatives may be added to the compositions and formulations of the present invention. As used herein a “preservative” is any substance or compound that is added to protect against decay, decomposition or spoilage. Means of preservation may also be utilized. Preservatives may be natural or synthetic. They may be antimicrobial preservatives, which inhibit the growth of bacteria or fungi, including mold, or antioxidants such as oxygen absorbers, which inhibit the oxidation of food constituents. Common antimicrobial preservatives include calcium propionate, sodium nitrate, sodium nitrite, sulfites (sulfur dioxide, sodium bisulfite, potassium hydrogen sulfite, etc.) and disodium EDTA. Antioxidants include BHA and BHT. Other preservatives include formaldehyde (usually in solution), glutaraldehyde (kills insects), ethanol and methylchloroisothiazolinone. A preservative, such as potassium sorbate can be added to the compositions or formulations. Typically, preservatives appear in the compositions at between 0.03 to 3% by weight percent.
Other Components
Optional components such as one or more dilute acids, other naturally occurring insecticides, sodium chloride and potassium soaps increase the range of activity of the base repellent composition with regard to the number of animal species repelled and the duration of the repulsive effect. Therefore, these may be added in suitable weight percent amounts. Other possible additives are perfumes, mineral or vegetable, optionally modified oils, waxes and nutrients (including trace nutrients), such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
Other Aromatics
The addition of cedar oil to the composition enhances the effectiveness of the composition as an animal repellent. It also adds ability to repel insects and kill mosquito larvae in water. Cedar oil may be added at between 0.03% and 10%. It may be added between 1% and 5%, between 2% and 4% or between 5% and 10%.
Cinnamon oil, clove oil and/or eugenol may be added to the composition enhances the effectiveness of the composition as an animal repellent. Cinnamon oil, clove oil and/or eugenol may be added at between 0.05% and 10%. It may be added between 1% and 5% or between 5% and 10%.
Camphor is a waxy, white or transparent solid with a strong, aromatic odor. It is a terpenoid with the chemical formula C10H16O. It is found in wood of the camphor laurel (Cinnamomum camphora), a large evergreen tree found in Asia (particularly in Borneo and Taiwan). It also occurs in some other related trees in the laurel family, notably Ocotea usambarensis. Camphor has been used as an insect repellent and may be added to the repellent compositions of the present invention in amounts of (by weigh percent) 0.01% to 15%. It may be added between 1% and 5%, between 2% and 4% or between 5% and 10%.
Pyrethrin
An additional optional component is a natural insecticide such pyrethrin. The pyrethrins are a pair of natural organic compounds that have potent insecticidal activity. Pyrethrin I and pyrethrin II are structurally related esters with a cyclopropane core. They differ by the oxidation state of one carbon and exist as viscous liquids.
The pyrethrins are contained in the seed cases of the perennial plant pyrethrum (Chrysanthemum cinerariaefolium), which is grown commercially to supply the insecticide.
When present in amounts not fatal to insects in the present formulations, they have an insect repellent effect. They are harmful to fish, but are far less toxic to mammals and birds than many synthetic insecticides. Pyrethrins are non-persistent, biodegradable, break down easily on exposure to light or oxygen and are considered to be among the safest insecticides for use around food.
Among the synthetic analogs of pyrethrin is permethrin. It is a member of the pyrethroid family and functions as a neurotoxin, by prolonging sodium channel activation and is the preferred synthetic pyrethroid although other members may be utilized in the present invention. The pyrethrins may be added at between 0.001% and 10%. It may be added between 1% and 5%, between 2% and 4% or between 5% and 10%.
Adjuvants
According to the present invention one or more adjuvants may be added to the repellent compositions. As used herein an “adjuvant” is a substance that aids, assists or improves one or more properties or activities of another substance.
Adjuvant categories include, but are not limited to, wetting agents and/or spreading agents (surfactants), sticking agents, adhesives, foam retardants, buffers, acidifiers, colorants, stabilizers and waterproofing agents.
Wetting/Spreading agents
A sprayed drop comprising an active agent, e.g., a repellent composition must be able to wet the surface and spread out or cover an area to perform its intended function. In some situations, a wetting agent (also known as a spreading agent or surfactant) is necessary for good coverage. A wetting agent/surfactant reduces the surface tension of the water on the surface of the spray drop and by reducing the interfacial tension between the spray drop and surface. This requires a surfactant that will preferentially aggregate at these surfaces. Surfactants wet and disperse particles of active ingredient(s) in the concentrate or upon dilution prior to spraying, and wet the target surface with the pesticide spray to achieve more effective coverage of the target. Concentrated multipurpose wetting agents typically contain a blend of bio-degradable, non-ionic surfactants and an emulsified silicone type anti-foam preparation. This action provides uniform wetting and coverage. Exemplary surfactants include amphoteric/zwitterionic surfactants; anionic surfactants; nonionic surfactants; cationic surfactants. Amphoteric surfactants useful in the invention can be described as a surface active agent containing at least one anionic and one cationic group and can act as either acids or bases depending on pH. Some of these compounds are aliphatic derivatives of heterocyclic secondary and tertiary amines in which the aliphatic radical may be straight or branched and wherein one of the aliphatic substituents contains from about 6 to about 20, preferably 8 to 18, carbon atoms and at least one contains an anionic water-solubilizing group, e.g., carboxy, phosphonate, phosphate, sulfonate, sulfate.
Zwitterionic surfactants can be described as surface active agents having a positive and negative charge in the same molecule which molecule is zwitterionic at all pH's. Zwitterionic surfactants can be best illustrated by betaines and sultaines. The zwitterionic compounds generally contain a quaternary ammonium, quaternary phosphonium or a tertiary sulfonium moiety. In all of these compounds there is at least one aliphatic group, straight chain or branched, containing from about 6 to 20, preferably 8 to 18, carbon atoms and at least one aliphatic substituent containing an anionic water-solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate or phosphonate. Examples of suitable amphoteric and zwitterionic surfactants include the alkali metal, alkaline earth metal, ammonium or substituted ammonium salts of alkyl amphocarboxyglycinates and alkyl amphocarboxypropionates, alkyl amphodipropionates, alkyl monoacetate, alkyl diacetates, alkyl amphoglycinates, and alkyl amphopropionates wherein alkyl represents an alkyl group having from 6 to about 20 carbon atoms. Other suitable surfactants include alkyliminomonoacetates, alkyliminidiacetates, alkyliminopropionates, alkyliminidipropionates, and alkylamphopropylsulfonates having between 12 and 18 carbon atoms, alkyl betaines and alkylamidoalkylene betaines and alkyl sultaines and alkylamidoalkylenehydroxy sulfonates. Anionic surfactants which may be used in the present invention are those surfactant compounds which contain a long chain hydrocarbon hydrophobic group in their molecular structure and a hydrophilic group, including salts such as carboxylate, sulfonate, sulfate or phosphate groups. The salts may be sodium, potassium, calcium, magnesium, barium, iron, ammonium and amine salts of such surfactants.
Anionic surfactants include the alkali metal, ammonium and alkanol ammonium salts of organic sulfuric reaction products having in their molecular structure an alkyl, or alkaryl group containing from 8 to 22 carbon atoms and a sulfonic or sulfuric acid ester group. Examples of such anionic surfactants include water soluble salts and mixtures of salts of alkyl benzene sulfonates having between 8 and 22 carbon atoms in the allyl group, alkyl ether sulfates having between about 8 and about 22 carbon atoms in the alkyl group and about 2 to about 9 moles ethylene oxide in the ether group. Other anionic surfactants that can be mentioned include alkyl sulfosuccinates, alkyl ether sulfosuccinates, olefin sulfonates, alkyl sarcosinates, alkyl monoglyceride sulfates and ether sulfates, alkyl ether carboxylates, paraffinic sulfonates, mono and dialkyl phosphate esters and ethoxylated derivatives, acyl methyl taurates, fatty acid soaps, collagen hydrosylate derivatives, sulfoacetates, acyl lactates, aryloxide disulfonates, sulfosuccinamides, naphthalene-formaldehyde condensates and the like. Aryl groups generally include one and two rings, alkyl generally includes from 8 to 22 carbon atoms and the ether groups generally range from 1 to 9 moles of ethylene oxide (EO) and/or propylene oxide (PO), preferably EO. Specific anionic surfactants which may be selected include linear alkyl benzene sulfonates such as decylbenzene sulfonate, undecylbenzene sulfonate, dodecylbenzene sulfonate, tridecylbenzene sulfonate, nonylbenzene sulfate and the sodium, potassium, ammonium, triethanol ammonium and isopropyl ammonium salts thereof.
The nonionic surfactant(s) may be any of the known nonionic surfactants which are generally selected on the basis of compatibility, effectiveness and economy. Examples of useful nonionic surfactants include condensates of ethylene oxide with a hydrophobic moiety. The surfactants include the ethoxylated primary or secondary aliphatic alcohols having from about 8 to about 24 carbon atoms, in either straight or branch chain configuration, with from about 2 to about 40, and preferably between about 2 and about 9 moles of ethylene oxide per mole of alcohol. Other suitable nonionic surfactants include the condensation products of from about 6 to about 12 carbon atoms alkyl phenols with about 3 to about 30, and preferably between about 5 to about 14 moles of ethylene oxide. Many cationic surfactants are known in the art and almost any cationic surfactant having at least one long chain allyl group of about 10 to 24 carbon atoms is suitable for optional use in the present invention.
Sticking Agents
A sticking agent can perform three types of functions. It can increase the adhesion or “stickiness” of solid particles that otherwise might be easily dislodged from a surface. It can also reduce evaporation of the formulation. The third function can be to provide a waterproof coating. If the sticking agent is not water soluble, it can provide a degree of protection from this form of loss.
Many of the sticking agents contain surfactants as their principal functioning agent and give both a sticking action and a wetter-spreader action. These will perform the first two functions quite well. But since the surfactants that provide wetter-spreader action must be somewhat water soluble, they may not provide good protection from rain. This will be provided by products that contain natural resins (rosin), or other waterproofing agents. Sticking-spreaders can be made of many different components, organic or inorganic. Some are silicone-based surfactants, oils, emulsifiers and buffering agents, while others may contain combinations such as fish oil or fatty acid soaps or emulsified soybean oil. Sticking agents include tackifiers. Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or lattices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations.
Adhesives
Adhesives, such as carboxymethyl cellulose, natural and synthetic polymers, (such as gum arabic, polyvinyl alcohol and polyvinyl acetate), and the like, may also be used in the formulations in the form of powders, granules or emulsifiable concentrations.
Foam Retardants
Some formulations will create foam in spray tanks as a result of both the surfactants used in the concentrate formulation and the type of spray tank agitation. This foam can be reduced or eliminated by a small amount of foam inhibitor.
Oil based defoamers have an oil carrier. The oil might be mineral oil, vegetable oil, white oil or any other oil that is insoluble in the foaming medium, except silicone oil. An oil based defoamer also contains a wax and/or hydrophobic silica to boost the performance. Typical waxes are ethylene bis stearamide (EBS), paraffinic waxes, ester waxes and fatty alcohol waxes. These products might also have surfactants to improve emulsification and spreading in the foaming medium.
Water based defoamers are different types of oils and waxes dispersed in a water base. The oils are often white oils or vegetable oils and the waxes are long chain fatty alcohol, fatty acid soaps or esters. These are normally best as deaerators, which mean they are best at releasing entrained air.
Silicone-based defoamers have a silicone compound as the active component. These might be delivered as oil or a water based emulsion. The silicone compound consists of an hydrophobic silica dispersed in a silicone oil. Emulsifiers are added to ensure that the silicone spreads fast and well in the foaming medium. The silicone compound might also contain silicone glycols and other modified silicone fluids.
EO/PO based defoamers contain polyethylene glycol and polypropylene glycol copolymers. They are delivered as oils, water solutions, or water based emulsions. EO/PO copolymers normally have good dispersing properties and are often well suited when deposit problems are an issue.
Alkyl polyacrylates are suitable for use as defoamers in non-aqueous systems where air release is more important than the breakdown of surface foam. These defoamers are often delivered in a solvent carrier like petroleum distillates.
Foam retardants or defoamers may be used in the compositions of the present invention between 0.5% and 10% by weight.
Buffers
Some water used for diluting formulations is alkaline (high pH). If the pH is sufficiently high and the pesticide is subject to degradation by alkaline hydrolysis, it may be necessary to lower the pH of the mix water to a pH in the range of 3 to 7, preferably 3.75 to 4.25. Buffers containing phosphoric acid or a salt of phosphoric acid, will lower the pH of the water and tend to stabilize the pH at an acceptable value. The efficacy of the buffer depends on its concentration of phosphoric acid and the degree of alkalinity or “hardness” of the mixing water that is being neutralized. The more alkaline the water, the greater the amount of buffer required.
Some buffers have sufficient surfactant present to also perform as wetter-spreaders. The concentration of surfactant and phosphoric acid are usually lumped together and it is not possible to determine the concentration of either and thus predict their efficacy. A useful range for phosphoric acid buffer concentration is from about 2 to 10%.
Acidifiers
Buffers that acidify alkaline spray waters increase the effectiveness. Buffers can help increase the residual life of the formulation about two-fold and can result in reducing the number of spray applications per season. Muriatic acid, Buffer-X or vinegar are not effective for this purpose. The duration and scope of effectiveness of the present invention may also be increased by adding a dilute acid to the composition, especially acetic acid, which may be in the form of vinegar, preferably white distilled vinegar having an acid content of between 3.5 and 5% acetic acid. Dilute acid may be added to the composition of the present invention between about 0.01% to about 5% by weight.
Colorants
It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc. Colorants are advantageous when it is important for the repellent compositions or formulations when applied to blend in, or be less detectable in the environment applied. This advantage is sometimes aesthetic but can serve a functional role where pests are likely to either be attracted or repelled based on color.
The use of these adjuvants provides a variety of benefits including improved coverage of the spray both in the soil and on plant surfaces, increased retention on surfaces, reduced evaporation, reduced foaming problems in the tank, easier sprayer cleaning and lubrication of pump and sprayer nozzles.
Stabilizers
Stabilizers, such as low-temperature stabilizers, preservatives, antioxidants, light stabilizers or other agents which improve chemical and/or physical stability may also be present. Stabilizers are useful to inhibit the reaction between two or more other chemicals. They can also inhibit separation of suspensions, emulsions, and foams.
Applications and Methods
The repellent compositions may be applied to any surface or substrate by any convenient method. It is expected that spraying will be the application method of choice in most circumstances where a liquid formulation is used. For example, an aircraft may be used to spray the liquid formulation over crops or fields. Other methods of application contemplated include, but are not limited to, painting, brushing, mopping, spreading, banding, broadcasting, side-dressing, coating, rolling, bathing, dipping, immersing, soaking, adhering, sticking, spraying, rubbing, wiping, impregnating, injecting, embedding, sealing, stippling, dotting, dabbing, stenciling, stamping, layering, spackling, sprinkling, aerosolizing, misting, dusting, vaporizing, pouring and the like.
Methods of application may also be indirect. For example, containers or vessels holding an amount of a repellent composition may be placed in an area to be treated with dispersion of the composition being effected by forces of nature, e.g., wind, rain, current, radiant heat. Air spraying apparatuses may be employed such as those disclosed in U.S. Pat. No. 4,172,557, the contents of which are incorporated herein in its entirety. Dispersion may also be effected from a container whereby dispersion is activated by movement such as a motion sensor. Aerosol dispersion is particularly amenable to automatic release via motion detection. Indirect methods also include the use of mechanical devices to effect the applications listed herein. For example, timed spreaders or broadcasters may be set up in predetermined areas in order to apply or disperse the repellents to a surface, area or substrate in a temporal fashion, e.g., automated application. Triggering of timed spreaders or timed distribution may be predetermined or may occur on signal either remotely initiated or initiated as part of a timed sequence after a detection event. For example, application of the repellent may occur at a time after trigger by a motion detector of the presence of a pest.
Indirect methods also include the use of devices such as those disclosed in U.S. Pat. No. 6,192,621, the contents of which are incorporated herein by reference in their entirety. In this application, the animal repellents, alone or in combination with other agents or repellents are installed in the animal control device capable of repelling or attracting pests to any area in which the device is placed.
In some embodiments, the present invention provides methods of storing or using seeds (e.g., vegetable seeds, grass seeds, flower seeds, bird seeds, sunflower seeds, plant seeds), that prevents pest visitation and/or consumption of such seeds. Such methods comprise the treatment of seeds with a repellent formulation of the invention to form a repellent seed composition. In some cases, seeds are further dried after treatment. Repellent seed compositions may be stored for a period of from about a day to about a week, from about 2 days to about 2 weeks, from about a week to about 4 weeks, from about 2 weeks to about 10 weeks, from about 5 weeks to about 50 weeks, from about 10 weeks to about 100 weeks, or from about 1 year to about 5 years with reduced or eliminated seed consumption by pests (e.g., rodents and birds). In some embodiments, such methods include the use of grass seeds. Grass seeds may be treated with repellent formulations and applied to areas for growing grass. Grass seeds comprising repellent seed compositions may be resistant to consumption by pests (e.g., rodents and birds).
Pest Management Systems
The present invention provides for a pest control management system or “pest management system” or “PMS” which are functional to control pest populations either by preventing ingress or egress or by attracting pests for containment and/or relocation as well as for extermination. In this system, a repellent (or attractant) formulation is incorporated into, used with a device which resembles, is disguised as, or is already an integral part of its environment. The system may also be used in conjunction with commercially available attractants and as such incorporate commercial or non-commercial baits, abatement systems, traps or bait boxes. The advantages of such a disguised trapping system include ease of use and a more acceptable presence. As such, they would be superior to unattractive traps and consequently be used more often which would, by definition, result in more trapped pests.
The repellent and/or attractant compositions useful in conjunction with the PMSs of the present invention include any of those of standard use in the art. It is of special interest to employ repellents and attractants which are generally accepted as safe (GRAS). Examples of such compositions are disclosed in, for example, commonly-owned International PCT filing PCT/US2011/031901 filed Apr. 27, 2011, the contents of which are incorporated herein by reference in their entirety.
Multiple pest management systems may be combined.
The body of the system may be the only portion which is disguised. The variable housing may be the only portion of the system which is disguised. The composition housing may be the only portion of the system which is disguised.
In one embodiment, the systems of the invention may be an object that is configured to resemble and/or disguised as an item that blends and/or integrates into its environment. As used herein, “configured to resemble” and “disguised as” refers to an object that is made to appear as, is similar to, takes on a false appearance of, is camouflaged as, and the like, that may occur in the environment in which the object is placed. As used herein, “blends” and “integrates into” refers to the ability of an object to appear natural or normal or native, incorporate, merge, mingle, assimilate, combine, coordinate, unite, and the like, with its environment.
Devices and means for application of the formulations as pest management systems include, but are not limited to, plant pots, plant pot saucers, vases, door jams, buckets, cans, pans, glass bottles, plastic bottles, used household container items, food container, any empty container, food items, articles of clothing such as socks, stockings, and the like, cardboard or degradable boxes, paper, newspaper, books, deck of cards, logs, rocks, outdoor equipment such as tents, tent stakes and the like.
A further embodiment is a pest management system which includes a signal to alert that a pest has been captured in or come close to the device. “Signal” as used herein refers to a sign, indication, indicator, gesture or object that conveys a notice to a person. A “signal” can include, but is not limited to, a flag, sound, smell (odor), motion, blinking light and the like. For example, a device may be a container configured to resemble a log with a compartment inside the log housing an attractant formulation and an opening to allow a pest to enter the device. Once a pest enters the device, the pest triggers a mechanism that closes the opening and the same or another mechanism causes a signal, such as a flag, to rise out of the device.
Formulations which function in a timed-release, extended release and/or controlled release manner are also contemplated by the devices of the present invention. As used herein “time release” or “timed release” refers to a composition which exerts its effect over a period of time. The period of time may be measured in days, weeks or months. “Extended release” refers to compositions which have been formulated to exert their effects over an extended period of time. Extended release compositions are by definition time-release compositions. Extended release compositions are those which exert their effects over a period of time greater than one week. As used herein “controlled release” means the liberation of the repellent composition of the invention into the intended environment in a regular manner or pattern. Controlled release formulations are often timed release formulations although the amount released in any one time across a gradient may vary.
Controlled release formulations in polymeric vehicles have been used for delivery of pesticides, insecticides, fertilizer, detergents, perfumes and in drug delivery. U.S. Pat. No. 5,017,377 to Sikinama et al. discloses a controlled release insect pest repellent used in many settings including p-menthane-3,8-diol blended with an ethylene vinyl acetate copolymer, and is herein incorporated by reference in its entirety.
Controlled release formulations of the present invention can be formulated using either non-degradable or degradable materials. In one type of polymeric delivery system, a polymeric capsule is formed around or incorporating the agent to be delivered. The type of agent being delivered and the environment in which the agent is intended to be used determine the composition of the polymer or polymers used and the method that can be used to incorporate the agent. Alternatively, the polymer can be in the form of a sheet, pellets, a film, or a shaped article.
Examples of controlled release devices and methods are disclosed in “Controlled-Release Delivery Systems for Pesticides” edited by Herbert Scher, 1999 CRC Press.
Timed release formulations of the invention may be prepared in any of several ways. They may be prepared and coated onto, contained within or encapsulated in a physical container, granule, polymer, substrate or barrier which breaks down, corrodes or erodes to release the repellent. When formulated in this manner, the granule, substrate or barrier composition need not be homogeneous in size or content. Hence the time release can be controlled by the size or make-up of the material or materials used as a substrate.
They may also be encapsulated within a coating or chemical layer which, upon contact with water, oxygen, or other environment, chemically reacts to dissolve or degrade the coating or layer thereby releasing the repellent.
Where encapsulation of a repellent formulation is desired, such as where the formulation is to be used in a time release manner or where direct contact with the repellent composition is undesirable, compression within a tablet or cake or containment within a capsule may be employed.
In the tablet/cake embodiment, the tablet formulation may comprise multiple layers comprising a different concentration of formulation in each. Layers may be the same size or vary in size based on the amount of formulation to be released. For example, a binary base formulation, with no additional ingredients may be used in the outer layer or layers for an early concentrated release of repellent while a more dilute formulation having longer release characteristics may be contained deeper within the tablet for extended release effect. In this embodiment, tablets or cakes may be formed in any shape or size suitable to the application. It is well within the skill of one in the agricultural art to form tablets or cakes.
For encapsulation, any number of biodegradable polymers or substrates may be used to surround an effective amount of repellent. The repellent compositions of the present invention may be encapsulated into a matrix by the methods disclosed in U.S. Pat. No. 6,500,463, the contents of which are incorporated herein by reference in their entirety. They may also be incorporated into hydrophobic thermoplastic polymers such as those described in U.S. Pat. No. 6,852,328 to form controlled release matrices. U.S. Pat. No. 6,852,328 is herein incorporated by reference in its entirety.
The repellent compositions of the present invention may also be formulated in hydrogel microbeads each comprising a plurality of active material droplets entrained within a hydrophilic matrix that is cured chemically as disclosed in U.S. Pat. No. 6,793,937, the contents of which are incorporated herein by reference in their entirety.
The repellent compositions of the present invention may be incorporated into inorganic polymer complexes for controlled release as in U.S. Pat. No. 6,391,336; employed in granulation methods alone or as an additive as in the methods of U.S. Pat. Nos. 6,331,193 and 6,299,663; combined with insecticidal proteins such as by the methods disclosed in U.S. Pat. Nos. 6,221,649 and 6,110,463; incorporated into biodegradable plastic products made of coconut mesocarp as disclosed in U.S. Pat. No. 6,083,621; combined with microencapsulated phase change materials such as those described in U.S. Pat. No. 6,057,266 to improve time release; may be incorporated into coated granular pesticide formulations such as those disclosed in U.S. Pat. No. 6,036,971; incorporated into the time release systems described in U.S. Pat. No. 6,004,572; encapsulated in thermoplastic resins such as those described in U.S. Pat. No. 5,679,129; layered into slow release granules such as those in U.S. Pat. No. 4,971,796; or adsorbed in organoclay controlled release formulations such as those disclosed in U.S. Pat. No. 4,849,006, the contents of each patent of which is incorporated herein by reference in its entirety.
Repellent formulations may also be formulated as granular beads or particles for use in post-sale encapsulation by the consumer. In this regard, the repellent formulation may be manufactured such that it may be poured into any fabric or wrapped in a material such as a stocking, sack, sachet, bag, garbage bag and the like. These allow the formulation to be hung or elevated. Alternatively, kits may be provided which include the formulation in combination with a means for application of the time release formulation.
The repellent compositions of the present invention may by applied using global positioning system (GPS) technology as disclosed in U.S. Pat. No. 6,199,000, the contents of which is incorporated by reference herein in its entirety.
The compositions of the present invention may be applied or delivered using osmotic devices such as those described in U.S. Pat. No. 6,491,949, the contents of which are incorporated herein by reference in their entirety.
Controlled delivery of the repellents of the present invention may be to a body of water such as is disclosed in U.S. Pat. Nos. 5,902,596, 5,885,605 and 5,858,384, the contents of each which are incorporated by reference in their entirety.
They may also be formulated for controlled release on land by incorporation into superabsorbent polymers such as those described in U.S. Pat. No. 4,983,390, the contents of which are incorporated by reference in their entirety. Time release may be effected via wicking of the repellent into the atmosphere. As used herein “wicking” is the process by which the repellent composition is moved via capillary action up a tube or along a material. In the present invention, the repellents may be formulated in candles or simply placed in a container with one or more materials used to “wick” the repellent out of the container into the atmosphere. Wicking can be facilitated or non-facilitated. Facilitated wicking occurs via the use of one or more external energy sources such as via the application of heat or use of a fan or both. Non-facilitated wicking occurs naturally in the absence of any applied external energy source, e.g., evaporation.
Time release may be effected by the direct application of heat to either the repellent alone or to the container in which the repellent is placed.
Time released repellent formulations may be placed around or inside buildings, garden areas, vineyards, turf areas, sports fields, parks, campsites, barns, farms, greenhouses, hung on stands or trees and the like. These may also be placed along side roads or other throughways such and walkways and entrances to limit animal entry. They may also be installed on or within vehicles such as under the hood to deter or prevent animal collision.
In one embodiment time release devices include porous bodies or other bodies that can contain a repellent composition and release the composition over time. One such device is a tube with a permeable wall. The tube is filled with a repellent composition such as, but not limited to, a repellent composition of the present invention. The tube is then used to form a boundary. For example, a garden prone to pests may be protected by placing the time release device around the garden. The device may be surface positioned or buried. The effect of the time release device is to deter insects and/or birds.
An exemplary container includes a formulation that comprises a repellent composition of the present invention wherein the container allows for time release of the formulation over a period of one month or more.
Patterned applications are also contemplated. Such applications may be in any shape or may be random. Application may occur in a circular, radial, oval, square, oblong or any other geometric shape necessary to effect coverage of the intended surface, area or substrate. Coverage of the repellent need not be complete or uniform in order to be effective. Coverage levels may be titrated based on the needed repellent effect. For example, coverage may be at the level of at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95% or 100%.
Repellents and Attractants
The pest management systems of the present invention may be used in combination with the repellents or with attractants known in the art. Attractant formulations of the present invention may comprise of one or a combination of the following natural substances: sugar, honey, molasses, pheromones, plant oils, plant extracts, floral odors, proteins, salt, animal oils such as fish oil and the like, seeds, animal feed, livestock feed, and sticky agents, adhesives including substances such as tanglewood and the like. They may also include commercial pest attractants including poisons. Attractants include compositions and formulations such as those known to those skilled in the art and also disclosed in U.S. Patent Publication Nos. 20100074860 and 20090258950, the contents of which are incorporated herein by reference in their entirety.
As an alternate procedure, the composition can be impregnated into or coated onto a surface to be protected. In this embodiment, a thickener or thixotropic agent is added to the composition.
In another embodiment, the repellent formulations of the present invention may be combined with the urine or one or more animals such as is disclosed in US pre-grant publication number US20100260862 entitled “Time release formulations and methods of making same” the contents of which are incorporated herein by reference in their entirety. The dot delivery apparatus and systems disclosed in US 20100260862 may also be employed using the composition of the present invention.
Both repellent and attractant composition may be applied to or installed in the devices in the form of aerosol, balm, cream, gel, lotion, mousse, patch, pump spray, roll on, solution, gel stick, solid stick, towelette, salve, ointment, powder, liquid, granules, candle, vapor, beads and the like. It is known to those in the art that “towelette” can also be known as a “wet wipe.” As an alternate procedure, the composition can be impregnated into crushed eggshells, nutshells or corncobs, wood chips, clay structures (such as clay balls, clay sheets, clay bricks, clay boats, or any other geometric shape), wood based cellulose granules, agglomerized cellulose or other particulate substrates and spread evenly over the area to be protected. For example, in order to produce a sustained release formulation, the repellent compositions of the present invention may act as the “pest control agents” in the compositions disclosed in U.S. Pat. No. 7,846,463, the contents of which are incorporated herein by reference in their entirety.
It should be clear that the particle size of these materials can vary. Particle size may range from dust sized particles to approximately 1 foot in diameter. In one embodiment, particulate substrates are heterogeneous in size and range from the size of a kernel of corn to that of standard wood chips. In one embodiment particulate substrates are from about 1 inch to 10 inches, 1 inch to 5 inches, 1 inch to 3 inches, or approximately 2 inches. Typically 1 to 10, 1 to 5, or 1 to 3 ounces of concentrated formula is used to wet 1 pound of granular or particulate material. In another embodiment, the particulate substrates may be soaked in either a concentrated formula or one which has been diluted according to the invention. Once dry, the 1 pound of granular or particulate product can be applied to 1000 square feet of surface area. Depending on the desired coverage, more than one application may be made.
In another embodiment, the composition can be left in containers which are distributed in a uniform manner around the area being treated.
Various types of solid materials may be protected by the disclosed repellent compositions. Plant material, including woody plants may be protected from browsing animals. Plant material including grasses, may be sprayed to prevent insects from alighting on the plant. Seed, including bird, vegetable, flower, plant, may be protected from wandering animals such as rodents, by mixing the repellent of the present invention with the seed to be protected.
Exterior surfaces of buildings, walls, concrete and asphalt and other solid non-living surfaces may be sprayed to prevent animals from alighting on, approaching or otherwise contacting such surfaces.
The repellent formulations may be applied to clothing or other fabric or sheet goods to prevent insects from alighting on the material or biting through the material. The fabric may be permeable or impermeable and may be woven or non-woven. Examples of materials to which the compositions may be applied are cottons and other natural fibers or synthetic fibers or sheet goods such as nylon, polyester or polypropylene. If the material is permeable the composition may be absorbed; if impermeable the composition will act as a coating on the surface of the fiber or sheet goods. In one embodiment, the repellent compositions may be mixed in a paper slurry and pressed into paper sheets such as napkins or tablecloths for outdoor use to deter insects. Paper products made in this way may be used to wrap around plants (stems, trunks or other parts) or cover physical structures to deter pest ingress or egress. They may also be mixed in screen printing fluids and printed onto articles of manufacture such as shirts or any fabric amenable to screen printing.
The formulations may be applied to articles of adornment such as jewelry or bands such as wrist bands, hats, caps or any head covering, covering for the hands such as gloves or mittens, as well as shoes, boots, waders, suspenders and the like. They may also be incorporated into systems having butane heated cartridges such as those designed to emit odors to ward off pests. The formulations of the present invention may be used in personalized pest repellent devices such as those worn around the neck, wrist, waist or ankle or those attached to clothing. The personalized pest repellent devices may be motorized or they may be passively activated. The motorized devices may depend on battery or solar power to run the devices. The personalized pest repellent devices may attach to a belt, hat, suspenders, backpack, purse, bag, pocket, shoe, boot, pants, shirt or jacket, or hang around the neck, waist, shoulder, or wrist.
The formulations may be applied to or mixed into candles. These candles may be citronella candles or decorative candles. The wax of the candle may be selected from the group consisting of but not limited to carnauba wax, candelilla wax, beeswax, synthetic wax, shellac wax, spermaceti, lanolin wax, ozokerite, bran wax, ceresin wax, bayberry wax, paraffin, rice wax, jojoba wax, soy wax, palm wax, candle gel and a combination thereof.
In one embodiment, the formulation may be applied to the skin, fur or pelt of pets and domestic or other animals such as, but not limited to, livestock in order to minimize insect problems. The formulation may be applied directly to the animal's coat or pelt by spraying, pouring or massaging the liquid formulation into the coat or pelt. Emulsions of polymers comprising the repellents of the present invention may also be used on the skin of animals as described in U.S. Pat. No. 4,783,335 the contents of which are incorporated herein by reference in their entirety. Pet accessories or adornments such as clothing, leashes, tags, or collars may also be treated with the formulations of the invention. Use of the composition on the surface of various farm structures, particularly on surfaces inside barns where animals are kept or milked will minimize insect interference with farm operations and animals. Livestock accessories or adornments such as harnesses, ear tags, saddles, reins, or blankets may also be treated with the formulations of the invention. The repellent compositions of the present invention may be used to improve cultivation methods and employed in methods such as those described in U.S. Pat. No. 6,887,828, the contents of which are incorporated herein by reference in their entirety.
In one embodiment, the formulation may be applied to the skin, fur or pelt of pets and domestic or other animals such as, but not limited to, livestock in order to repel predators.

An animal or insect repellent may be prepared by coating about 4 ounces of repellent formulation selected from formulations A-M of Tables 6 and 7 onto about one pound weight of straw, hay, seeds, grains, ground corncob, mulch, wood particles and/or compressed wood, and the mixture is then freeze-dried.
Example 11
Personal Repellent Apparatus for Humans
An animal or insect repellent to be worn by humans may be prepared where the about one ounce of the liquid repellent formulation selected from the formulations A-M of Tables 6 and 7 is coated onto an inch-square polymer, cloth, or paper and stored in an apparatus which may attach to clothing, fabric or a person. For example the apparatus can attach to a belt, hat, suspenders, backpack, purse, bag, pocket, shoe, boot, pants, shirt, and/or jacket, or hang around the neck, waist, shoulder or wrist.
Example 12
Candle Repellent Formulation
A candle of the animal or insect repellent formulation may be prepared by mixing about three ounces of the repellent formulation selected from the formulations A-M of Tables 6 and 7 and about two ounces of citronella into about a half of a pound of melted soy wax, pouring the wax around a wick, and allowing the wax mixture to dry creating a candle. The candle may be lit so the flame melt the wax and disperse the formulation into the air. The formulation may also be released by using a warming plate to melt the wax and disperse the formulation into the air.
Example 13
Gel Repellent Formulation
A gel of the animal or insect repellent formulation may be prepared by mixing about four ounces of the repellent formulation selected from the formulations A-M of Tables 6 and 7 and about two ounces of citronella into about a quarter of a pound of liquid gel wax and the mixture is poured into a mold to solidify after which the solidified mixture may be exposed to air to disperse the formulation.
Example 14
Repellent Formulation for Pets
A liquid formulation of the repellent formulation selected from the formulations A-M of Tables 6 and 7 may be prepared by mixing about two ounces of solvent with about one ounce of the selected repellent formulation. The formulation may be used to coat pet collars, tags, or pet clothing which is then attached to the pet or the liquid formulation may be applied directly to the pets coat by spraying, pouring or massaging the liquid formulation into the coat.
Example 15

Repellent Seed Composition
Formulation Q, described previously, is combined with seeds in the amount of 10 g of Formulation Q per pound of seeds to produce a repellent seed composition. Treated seeds are resistant to consumption and destruction by birds, rodents and insects.
Example 28
Rodent Repellent Assay
In a warehouse situation, a repellent seed composition was prepared by treating birdseed with Formulation Q (10 g of Formulation Q/pound of seed) and then used as bait. Treated seeds were placed in a dish and a light film of fine sand was spread around the dish for a distance of 3 to 4 inches around the dish. The sand around the dish was used to detect mouse visitation to the baited seed in the dish. In the following mornings, the test site was visited to see if there was any mouse or rat activity in the test dish and sand preparation. The test site was replicated 6 times including a control site with a dish of seeds that were not treated. Although all test sites were visited by mice (as shown by their footprints in the sand), none of the test dishes with treated seeds had noticeable seed missing, whereas the untreated seeds in the control site were totally missing. Test site inspection continued every morning for about 2 weeks showing little or no treated seed missing. Although mice visited the treated seed, surprisingly, they were highly repelled by the seed treatment.
Example 29
Granular Repellent Composition
A granular repellent composition is prepared. Formulation C3, described previously, is combined with crushed walnut shells in the amount of 19.5 g of Formulation C3 per pound of crushed walnut shells. The treated material is allowed to dry. The treated walnut shells are used to repel rodents and other pests.
Example 29
Groundhog Repellent Assay
In a natural field situation, a groundhog hole (e.g. borough) was found and sealed with soil to verify that the hole was actively used. If the soil was removed within 24 hours, then the hole or entry was an “active site” being used by the groundhog. In active sites, 8 ounces of a granular repellent composition (comprising crushed walnut shells treated with the concentrated formulation of C3 at a ratio of 19.5 g of C3 per pound of crushed walnut shells) was thrown into the hole and covered with soil. An additional 8 ounces of treated material was spread around the entry hole. This was replicated in 2 other holes that were found in the area. After 14 days had passed, only one of the 3 entries was breached by the groundhog. It was retreated and no further entry into any of the holes was observed for the remainder of the summer.
