The Alameda County Agriculture Department is responsible for enforcing laws and regulations pertaining to the use of pesticides. We inspect businesses and those who apply pesticides in and around homes, offices, parks, streets, farms, and ranches. Pest means anything that is or may become dangerous or detrimental to the agricultural or non-agricultural environment. Pest can be any insect, predatory animal, rodent, nematode, or weed. It can mean plants and/or animal pests on and, in the water, or in the air. It can also include virus, fungus, bacteria and other microorganisms. Pesticides are any substances which are used for preventing, destroying, repelling, or controlling any pest which may infest or be detrimental to vegetation, man, animals, or households.

Our staff provides training and advice on pesticide use, pest control, and pesticide safety. We do about 1,500 inspections a year. We also investigate complaints of pesticide misuse and follow up on doctors' reports of suspected pesticide exposure.
