History of the District

In 1915, the California Legislature adopted the “Mosquito Abatement Act” to help protect people from health risks associated with mosquitoes. This provided the basis for creating Mosquito Abatement Districts throughout the state. Click HERE to view mosquito abatement's governing laws of the California Health and Safety Code.

The Lake County Mosquito Abatement District was formed in 1947. The driving force behind the formation of the District was a need to control the pestiferous Clear Lake Gnat (Chaoborus astictopus). By 1976, Clear Lake Gnat populations were in decline, although the exact reason for their sudden disappearance from the lake remains a mystery to this day. In the 1980's, with the gnat populations under control, the District's research and control efforts shifted to protect the public against diseases transmitted by mosquitoes and relief from serious pest nuisance.

In July of 1990, the District Board voted to change the name of the District to the Lake County Mosquito and Vector Control District.

The District is governed by a Board of Trustees, each representing one of the incorporated cities within the District’s boundaries.  Each Trustee is appointed by a City Council Member or by the County Board of Supervisors.  Board meetings are held at 1:00pm on the second Wednesday of each month in the Lake County Vector Control Board Room (Click HERE for location).
