Integrated Vector Management (IVM) is an ecosystem-based strategy, that focuses on the long-term prevention of pests or their damage through a combination of techniques such as public education, biological control, physical control (habitat manipulation), vegetation management, microbial control, vector surveillance, and chemical control. Pesticides are used only after monitoring indicates they are needed according to established guidelines, and treatments are made with the goal of removing only the target organism. Pest control methods are selected and applied in a manner that minimizes risks to human health, beneficial and non-target organisms, and the environment.

All pesticides used by the District have been tested and approved by the Federal and State Environmental Protection Agencies for use in public health mosquito control programs and are applied by trained and licensed technicians as part of an integrated vector management (IVM) program. Our program is in full compliance with all applicable Federal and State regulations including the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), the Clean Water Act (CWA), the California Environmental Quality Act (CEQA) and the California Health and Safety Code. The use of source reduction, biological control, and biorational pesticides minimizes impact on the environment while protecting the public from mosquito-borne disease and nuisance problems.

The US Environmental Protection Agency website has detailed information on pesticides used in mosquito control.
