The Pesticide and Pest Management Division is comprised of three main programs, Pesticide Enforcement, Pest Management and Pest Eradication, and two minor programs, Native Plant Protection and Apiary Regulation.

The Pesticide Enforcement program focuses its efforts on protecting the public and the environment from improper pesticide use. Pesticide use in agricultural and urban settings is routinely inspected to ensure that the pesticide is used correctly. Prior to any agricultural use, growers must pass an exam on safety, proper use and applicable regulations. Use permits are issued to growers after evaluating the impact on the surrounding area and restrictions placed on use to minimize the hazards of the pesticide. In the urban settings, all pest control companies and their employees are required to be licensed by the state. Audits and inspections verify that only qualified people apply pesticides in and around homes. Homeowners are exempt from this requirement.

Employees of businesses using pesticides are required to be trained prior to using pesticides or working in agricultural areas where pesticides have been applied. Record audits and interviews with agricultural laborers verify compliance. In addition, all pesticide use is reported to us which allows another means of monitoring usage.

The Pest Management program’s staff manufacture rodent baits for sale and spray herbicides along roads and flood channels to eliminate weeds. By the careful application of herbicides by our licensed staff, roadside fire hazards are eliminated, visibility is improved and maintenance costs are reduced. Last year, over 6,500 acres of land were treated. Other department staff provide free pest control advice and pest identification service to the general public.

Despite the best efforts of the people in the Pest Exclusion Division, some pests become established in the County. When this happens, the Department evaluates the situation and launches an eradication program when feasible. Currently the Pest Eradication program is dealing primarily with weeds such as halogeton, knapweeds and yellow star thistle. You can learn more about these pests in Pest Prevention section.

Beekeepers are required to have permission to use the property where they place their colonies of bees and to provide water for the bees. Often, the water source dries up and the bees invade local residential areas in search of water. The Apiary program resolves complaints regarding commercial beekeepers and provides disease inspection services for beekeepers moving bees out of state.

The Native Plant program regulates the removal of cactus, yuccas and other desert plants. Commercial harvesting of these plants has not occurred in over ten years because the harvested areas were not recovering as expected. Property owners can remove five or fewer native plants without a permit provided that they are not selling the plants. In situations involving building sites, removal permits are issued with the building permit.
