Contra Costa Mosquito & Vector Control District

What Contra Costa Mosquito & Vector Control District does

Contra Costa Mosquito and Vector Control District is a California special district established in 1927 that delivers mosquito and vector control services to all residents of Contra Costa County, California. The District operates from its headquarters in Concord and provides free services including property inspections, mosquito treatments, mosquitofish distribution, unmaintained-pool remediation, tick and stinging-insect identification, rodent and skunk inspection, yellowjacket nest treatment, and bee swarm management. Its operational footprint covers over 10,000 acres of marshland, irrigated farmland, ponds, creeks, and residential sources across the county.

The District's technical core is Integrated Vector Management (IVM), an ecosystem-based pest-control strategy combining biological control, habitat manipulation, cultural practices, and targeted pesticide application. Distinct technical capabilities include the Innovative Mosquito Reduction (IMR) program using Wolbachia-treated sterile male Aedes aegypti releases, unmanned aerial drone surveillance and treatment in hard-to-reach areas, and the in-house Marilyn Milby Entomology Laboratory, which conducts West Nile virus surveillance, invasive-species monitoring, and specimen identification. Service delivery combines a self-serve online portal, phone intake, walk-in pest identification, field inspections, and active community education outreach including Spanish-language resources.

The District is funded entirely through Contra Costa County property taxes and special benefit assessments on benefiting properties, with services provided at no additional charge to residents. There is no commercial revenue stream, no equity investors, and no parent company; the entity is governed by a Board of Trustees under California special-district law. Its customer base is the entire county population (~1.1M residents), segmented geographically, with no per-unit pricing and no churn risk in the conventional sense.

Public Affairs staff engage with media, communities, and the public to advance mosquito-borne disease prevention.
• Integrated Vector Management (IVM) Program Ecosystem-based pest control strategy focusing on long-term prevention of pests and their damage through biological control, habitat manipulation, modification of cultural practices, and use of resistant varieties, with pesticides applied only when monitoring indicates they are needed.
• West Nile Virus Activity Tracking Interactive mapping service tracking mosquitoes, dead birds, chickens, and horses that have tested positive for West Nile virus throughout Contra Costa County. Residents and stakeholders can zoom, pan, and click place-markers for detailed activity information.
• Tick and Biting Insect Identification Identification service for ticks, mosquitoes, and other stinging or biting pests submitted by Contra Costa County residents. Residents can bring samples to the District office, with results typically provided within two business days.

• Lee County Mosquito Control District: Florida mosquito control district also operating as an independent special district with property-tax funding; relevant peer for biological control methods, aerial/drone operations, and Aedes-borne disease response.
• San Diego County Vector Control Program: County-run mosquito and vector control program serving San Diego County residents with surveillance, control operations, and disease testing — directly comparable in mandate and geographic scope.

Broad incumbents

• Orkin (Rollins, Inc.): Largest U.S. pest control operator with broad residential and commercial mosquito/vector service offerings; relevant as the private-sector incumbent whose services are effectively replaced by public districts like Contra Costa in their jurisdictions.

Emerging players

• MosquitoMate: Commercial provider of Wolbachia-based mosquito control technology — directly comparable because Contra Costa's IMR program uses the same biological mechanism; useful as a technology vendor/adoption peer.
