A pesticide permit, legally referred to as an operator identification numbers, or Op-IDs, allows a CEQA-equivalent review of proposed agricultural and commercial* pesticide. Op-IDs are issued by our office to persons desiring to apply pesticides in agricultural areas (agricultural production, parks, golf courses, cemeteries, rights-of-way). Op-IDs are only issued to the property operator or their authorized representative.
*Commercial use is determined by the label of the pesticide. Not all pesticide manufacturers give both home use and commercial rates on their labels. If you wish to purchase and use a pesticide that only has commercial use rates, you will be required to obtain an operator ID permit from the county before you can purchase that pesticide, even if you are making the application in private, personal use situations.
If you are a maintenance gardener and use herbicides or any other type of pesticides, including those for rodent or ant control, you are required to become licensed by the Department of Pesticide Regulation. Licensing information is available online.
If using a restricted material for the commercial production of an agriculture commodity, including nurseries, vineyards and timber, you will also be required to have a either a QAC/QAL from DPR, or a Private Applicator Certificate from our department to be eligible for a restricted material permit.
