It's Renewal Season!

To avoid penalty fees, renew your pesticide and SPI license by January 1, 2025. You can submit renewals online or by mail. You cannot renew online if you are the Commercial Applicator for more than one company or have not renewed your license in the last two years. For more information about submitting your renewal visit: License Renewal | Washington State Department of Agriculture.
