Pesticide Control Act and Pesticide Application Act. The Washington State Department of Agriculture (WSDA) administers the state Pesticide Control Act and the state Pesticide Application Act. Its activities include adopting rules requiring the registration and restricted use of pesticides, testing and certifying pesticide applicators, issuing handler and worker pesticide training documentation, and providing technical assistance to pesticide applicators and workers.
All individuals who are licensed, or who are required to be licensed as pesticide applicators, pesticide operators, structural pest inspectors, and pest control consultants, must be certified through examination in the area in which they operate or consult. To be certified, a person must attain a passing score of at least 70 percent on a certification examination.
Examinations are administered by WSDA, and WSDA collects a fee from the applicant for each exam at an amount set in rule. License classifications address the control of a variety of pests, including insects and diseases, pest animals in agricultural situations, aquatic pests, both generally and in irrigation systems, and weeds.
Beginning January 1, 2026, a person may not use neonicotinoid pesticides on outdoor plants in this state, except on non-blossoming plants during the production of an agricultural commodity. Neonicotinoid pesticides must be designated as state restricted use pesticides if the pesticide label contains a section with the heading agricultural use requirements or nonagricultural use requirements.
Upon identification of an urgent pest threat, the Director of WSDA (Director) may authorize the sale, possession, or use of neonicotinoid pesticides by written order. The Director must make reasonable efforts to inform the public of the urgent pest threat identified. The written order must include certain information, including:
The provisions of this act do not apply to appropriately licensed individuals conducting research of neonicotinoid pesticides in accordance with all other pesticide laws and rules.
WSDA must review and update rules related to neonicotinoid pesticides by June 30, 2025, and every four years thereafter.
