      1. The invention relates to a method of repelling animals, to repellent concentrations and a method of repellent application.  
      2. Repellents have been used in attempts to protect stored agricultural products in containers and in bulk storage.  
      3. The specific repellent varies depending on the species of animal, bird or insect, which it is to repel.  
      4. U.S. Pat. No. 4,668,294 used thujone oil with a liquid or solid carrier such as lacquer, alcohol, sodium silicate, paraffin or sawdust to repel rodents. Thujone oil is a derivative of the cedar tree and is a natural repellent.  
      5. U.S. Pat. No. 5,402,597 uses extract of the herb camomile as a rodent repellent. The form of camomile used or the manner of placing the camomile in the area where rodents are not desired is not critical to the effectiveness of the camomile. The amount of camomile used is not critical. It is only necessary that a sufficient amount be used. The camomile repellent is effective for several months and loses potency with time. Reapplication may be required to maintain repellency.  
      6. U.S. Pat. No. 4,661,504 uses denatronium saccaride, a known bittering agent, as an animal repellent at low concentrations. It is used at 0.001 to 0.5% by weight of the composition. It is applied with a penetrating solvent and water. The bitter taste deters many species of chewing and gnawing animals.  
     BRIEF SUMMARY OF THE INVENTION  
      1. It is the objective of this invention to provide a repellent for chewing and gnawing animals which utilizes a naturally occurring plant derivative.  
      2. This product repels effectively and has minimum toxicity to the animals or to the individuals making the application.  
      3. Clove oil is a natural repellent with a unique strong odor and flavor. The odor is long lasting and not detrimental to the environment.  
      4. The repellent is effective when applied at a concentration of 1 to 10% of the natural concentration of commercial clove oil extract.  
      5. Sprays of the clove oil repellent in a 1 to 10% aqueous solution provided rodent repellency for 3 months in a rodent accessible commercial seed storage facility containing bagged grass seed. Mice and rats were present in the non-treated bags of seed and had chewed the untreated bags of grass seed.  
      6. Paper and plastic seed storage bags containing grass seed were sprayed with the repellent. These bags were undamaged by rodent activity three months later. Untreated bags were damaged by rodent chewing and feeding.  
     BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING  
      ‘Not Applicable’ 
    
    
     DETAILED DESCRIPTION OF THE INVENTION  
      1. Clove oil is a common plant oil. It is used for a variety of topical medicinal purposes. Clove oil has been used in topical applications on diseased teeth to lessen pain. It is used in cooking applications in some SE Asian cultures.  
      2. Clove oil has a strong smell and distinctive taste which chewing and gnawing rodents find undesirable. When a sufficient amount is sprayed in an aqueous solution upon seed in storage bags, bulk containers, and wooden pallets, the rodents will not eat the seed or chew the seed bags. Its odor and taste repel the rodents. The amount of clove oil used in the concentrations useful in this invention are non-toxic to people and domestic animals. The clove oil repels the rodents.  
      3. The form of clove oil used is an aqueous solution of 1 to 10% concentration of the natural concentration of commercial clove oil. This concentration is sold commercially as “one-fold” concentration of natural clove oil.  
      4. The scent and taste are the critical components. The most efficient method to protect seed in bags has been to spray the outside of the bags with the aqueous solution. Wooden pallets containing the treated seed bags also are sprayed with the clove oil.  
      5. The amount of clove oil is not critical. It is only necessary that a sufficient amount be used. Clove oil is the active ingredient of the repellent.  
      6. In seed storage buildings treated with clove oil, rodents have left for other dwelling sites. The repellency has been effective for up to 3 months. Repeated applications will maintain the effectiveness of this repellent over time.  
      It will be understood that the above embodiments are for purposes of illustration only. Changes and modifications may be made without departure from the spirit and scope of the invention.
