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. View our governing laws of the California Health and Safety Code..

On June 18, 1946, the Sacramento County-Yolo County Mosquito Abatement District was formed. The driving force behind the formation of the District was the need 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 Sacramento-Yolo Mosquito and Vector Control District to better reflect the expanded services regarding ticks, yellow jackets and other vectors.

The District is governed by a Board of Trustees, each representing one of the incorporated cities or one of the counties 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 10:00am on the third Tuesday of each month in Elk Grove.
