If you have pesticides (liquid or solid) that you no longer need, they must be disposed of properly so that they do not harm you or the environment. Any leftover pesticides must be taken to your local household hazardous waste (HHW) facility. You can find your nearest HHW location by calling the California Environmental Hotline (1-800-253-2687). Residents may only dispose of empty pesticide containers in the trash without rinsing them.
TAKE ACTION! Any amount of unused pesticide must be disposed of at your local household hazardous waste facility or event. Regardless of what the label may say, it is illegal in California to dispose of any amount of pesticide in the trash. To properly dispose of your unused chemicals, take them to the San Joaquin County Household Hazardous Waste Consolidation Facility (7850 R. A. Bridgeford Street, Stockton, CA 95206). This facility is open to the public, free of charge on Thursdays, Fridays, Saturdays, and Sundays from 9 AM – 3 PM. For more information, call the County Solid Waste Office at (209) 468-3066 or visit their website: https://www.sjgov.org/department/pwk/solid-waste/san-joaquin-county-solid-waste-facilities/san-joaquin-county-household-hazardous-waste-facility
