What do you need today?


Commercial Operator

The purpose is to license employees of companies that commercially apply pesticides. Pesticides include herbicides, insecticides, fungicides, rodenticides, fumigants, etc.
Applying pesticides to the lands/property of another while employed by a Commercial Applicator company requires the license.
Because exams are required, you must make your initial application at a WSDA testing session. These are offered at a number of statewide testing locations. WSDA does reciprocate with some state and federal licenses so testing may not be necessary. Go to the online reciprocal licensing information for details.
The license costs $85. In addition, the applicant must pay a $25 testing fee each time they take pesticide exams.

License application fees are non-refundable.

Effective November 1st, 2021, all pesticide license fees increased as a result of Senate Bill 5317. $7 of every license paid will help support the Washington State University's pesticide safet education program.
Applications are completed at the time of testing. The first time an application is submitted in a calendar year, the license fee of $85 is required. Each time tests are taken, a $25 testing fee and picture ID is required.
Applicant must pass required exams and have paid all fees before a license is issued. The license is only valid while making pesticide applications as an employee of a WSDA licensed Commercial Applicator.
Once all requirements have been met (complete application submitted including fee and appropriate exams passed), the license is normally issued within 1 week. However, the work unit experiences a heavier than normal workload from December – March and licenses can take 2 – 4 weeks to issue.
The license is annually renewed but in a five-year recertification cycle during which time continuing education credits must be earned. An alternative to recertification is to retest every five year.
The requirements for Commercial Operator licensing are found in the Washington Pesticide Application Act (chapter 17.21 RCW) and the General Pesticide Rules (WAC 16-228).
