Pesticide active ingredients are formulated in many ways. Choose the formulation best suited to your site and the pest you are trying to control. Aerosols, which contain one or more active ingredients and a solvent. They are ready for immediate use as is. Dusts, which contain active ingredients plus a very fine dry inert carrier such as clay, talc, or volcanic ash.
Dusts are ready for immediate use and are applied dry.
Granulars, which are similar to dusts, but with larger and heavier particles for broadcast applications. Baits, which are active ingredients mixed with food or other substances to attract the pest. Some also may be used as dusts. Depending on the type of formulation you choose, you may need to dilute or mix the product. Once you have identified the pest, selected the right pesticide, and determined proper dosage, you are ready to use the product.
