County Registration for Pest Control Companies and Pest Control Advisors

Beginning in 2022 we moved to an online registration system on CalAgPermits. Please log in to your CalAgPermits online account to find a new registration option on the dashboard. If you need an online account or help logging-in, please contact us at (650) 363-4700 or via email at 

Online registration is strongly encouraged. However, mail-in registration forms will also still be accepted by our department.
