Pest Control Operators

Our Pesticide Regulation Division serves to protect public health and safety, pesticide handlers, agricultural workers, and the environment from the harmful effects of pesticide misuse.

Professional pest control operators, advisers, commercial applicators, growers, pesticide dealers, and other users are regulated for the purpose of preventing the inappropriate or illegal use of pesticides.

The Division collects samples to be analyzed by the toxicology laboratory for project monitoring and agricultural or structural pesticide related investigations.

We offer training for other county personnel, governmental agencies, schools and private applicators in the safe and effective use of pesticides. This training is to ensure pesticide usage complies with state and federal laws and regulations, is appropriate, and minimizes risks to humans, animals, and the environment.

Any business that advertises, solicits, or operates as a pest control business in the County of Los Angeles must be registered with our Department. Businesses that perform pest control work incidental to their work, such as a Maintenance Gardener, must also be licensed and registered.


The examination for the Qualified Applicators License or the Qualified Applicators Certificate is given by the California Department of Pesticide Regulation (DPR). The application packet and exam schedule is available at our Department Headquarters or at the DPR website.

The examinations for the Structural Pest Control Operator and Field Representative licenses are given by the Structural Board. Click the button below to visit the Structural Board's website.
