Private Applicator Licensing

Individuals who apply Restricted Use Pesticides (RUPs) must be certified to do so under the Federal Insecticide, Fungicide and Rodenticides Act (FIFRA) and the Wyoming Environmental Pesticide Control Act of 1973. Amendments to FIFRA require that applicators be continually re-certified. Safety Education programs are conducted by the University of Wyoming Extension. Licensing is conferred by the Wyoming Department of Agriculture (WDA), which enforces FIFRA and the state act (statutes) in Wyoming.

A Private Pesticide Applicator is an individual sixteen (16) years of age or older who is licensed to apply or supervise the application of RESTRICTED USE PESTICIDES (RUP) to their own properties, either owned or leased, or who may apply restricted-use pesticides for other individuals on their properties, owned or leased either for no charge, or as an exchange of services, but not for pay, in the production of an agricultural commodity. Applicator classification is not related to either the amount of pesticides applied, or to the amount of acreage treated.
