Our Mission

Our mission is to support public health through the suppression of vector populations to reduce outbreaks of human diseases and public nuisances and increase the quality of life for the residents of the District.
To accomplish our mission we will employ integrated vector management techniques which include public education and outreach, surveillance, biological control, physical control and/or habitat modification, chemical control, research, partnering with other agencies and legal action where necessary and as governed by federal and state law.


Our History

For many years, the Los Angeles County Department of Health Services provided mosquito control in the San Gabriel Valley for cities not covered by a mosquito abatement district. The formation of our District was a direct result of a mosquito transmitted disease called St Louis encephalitis (SLE).
In 1983 this disease was reported in Los Angeles County for the first time since the 1940s. In 1984, an epidemic of SLE occurred; sixteen cases and one death were reported. In 1986 three more cases were reported. In order to reduce the threat SLE posed to public health, the San Gabriel Valley Mosquito Abatement District was formed in August 1989 as an independent special district.
Our goal is to protect the health of our residents by providing public education, vector control, and surveillance for vector-borne diseases through environmentally sensitive means such that the health of natural systems is protected.
The District covers 259 square miles and includes 23 cities: Alhambra, Arcadia, Azusa, Bradbury, Claremont, Covina, Duarte, El Monte, Glendora, Industry, Irwindale, La Puente, La Verne, Monterey Park, Monrovia, Pomona, Rosemead, San Dimas, San Gabriel, Sierra Madre, Temple City, West Covina, Walnut, and unincorporated portions of Los Angeles County. The unincorporated areas of Altadena and Kinneloa were annexed to the District in 2002.
As the District has evolved, our services have increased to include the following:

  • 1995 - Africanized honey bee control program.
  • 1996 - Surveillance and control of black flies.
  • 1997 - Full vector surveillance and control program adopted and we changed our name to San Gabriel Valley Mosquito & Vector Control District. 

We now provide surveillance for other vector-borne diseases such as West Nile virus.
We currently employ 19 full time staff and are governed by a board of trustees that consists of 24 members. A trustee is appointed from each of the member cities in our District and a representative from the County of Los Angeles.

In 2014 the district reached a milestone as it celebrated 25 years of protecting the San Gabriel Valley from vector-borne diseases.
