About the San Gabriel Valley Mosquito and Vector Control District

The San Gabriel Valley Mosquito and Vector Control District provides mosquito and vector control services in Los Angeles County, protecting over 1.5 million residents across 26 cities in the San Gabriel Valley. Our mission is to provide the highest level of protection from vectors and vector-borne diseases in the San Gabriel Valley. Our team works year-round to monitor, control, and prevent mosquitoes, black flies, and other vectors through science-based strategies, community education, and responsive service.

What Does a Vector Control District Do?

Under the California Health and Safety Code, the San Gabriel Valley Mosquito and Vector Control District  ("The District”, “SGVMVCD” or “SGVmosquito”) is a public health agency responsible for managing organisms called vectors. Vectors can transmit diseases to humans and animals.

At SGV Mosquito, we focus on:

• Mosquito surveillance and control
• Prevention of mosquito-borne diseases
• Inspection of standing water sources
• Public education and outreach
• Responding to service requests from residents

Our work helps reduce health risks and improve the quality of life throughout the San Gabriel Valley.

How Is Mosquito and Vector Control Funded?

The San Gabriel Valley Mosquito and Vector Control District is a public agency funded primarily through local property taxes and benefit assessments within Los Angeles County. This funding allows us to provide mosquito control and vector control services to residents at no additional cost at the time of service. 

All funding is used to protect public health and reduce the risk of mosquito-borne diseases in the communities we serve. We are committed to transparency and responsible use of public funds, with oversight and accountability built into our operations.

Integrated Vector Management (IVM)

Our work is guided by an Integrated Vector Management (IVM) program, a comprehensive strategy that uses multiple methods to control mosquitoes efficiently and responsibly.

IVM includes:

• Biological control (e.g., mosquito fish)
• Environmental management (eliminating breeding sites)
• Public education
• Area-wide pesticide use when necessary

This balanced approach ensures effective mosquito control while minimizing environmental impact.
