About Us

The Marin/Sonoma Mosquito and Vector Control District protects public health and welfare through an Integrated Vector Management Program (IVMP). A fully equipped laboratory supports the work of certified vector control technicians, who conduct surveillance for mosquitoes throughout Marin and Sonoma Counties (see map). Approximately 5,000 requests for service are received each year from residents and an inventory of over 20,000 known mosquito sources is checked regularly. Surveillance is also conducted regularly for invasive mosquitoes (Yellow Fever, Asian Tiger) that have become established in many areas of California.

The District’s progressive IVMP emphasizes methods such as education, outreach and physical and biological control (mosquito larvae eating fish), which are collectively known as source reduction. Where necessary, control of the 23 species of larval and adult mosquitoes found in the area is accomplished by the use of environmentally compatible materials applied carefully and responsibly by certified technicians (see Labels and SDS tab). District staff  also works cooperatively with local, state and federal agencies, to prevent large populations of aggressively-biting mosquitoes from hatching from the extensive marshlands and restored wetlands found in the area.

Ticks are collected regularly and tested for Lyme and other tick-borne diseases with results provided to the public and the California Department of Public Health. An advice and on-site inspection program offers assistance with rodent infestations, and staff will remove yellowjacket nests found in the ground. An insect identification specialist assists the public in identifying insects. 

The District’s authorizing statute is the California Health & Safety Code, § 2000 et seq., also known as the Mosquito Abatement and Vector Control District Law.
