In Sutter County, a local government agency has been suppressing mosquito populations for 7 decades

The Sutter-Yuba Mosquito and Vector Control District Facebook page has a lot of information presented in a fun way. (If you guessed midgut, you were right.)

The Sutter-Yuba Mosquito & Vector Control District is a local government agency that is not well known, despite its role in making the valley floor along the lower Feather River tolerable for human beings year-round. Since 1946, the District has interrupted mosquito breeding cycles and educated the public about the relationship between standing water, mosquitoes, and disease. 

The mission of the District is clear in the first paragraph of its online history ( “Before California was settled by pioneers and gold seekers, thousands of seasonally flooded acres of lowlands, marshes and other wetlands produced hoards of mosquitoes impacting the lives of Native Americans. Certain evidence of an archeological and anthropological nature suggest that these native cultures were seasonally compelled to move or abandon coastal and lowland areas. Unmitigated mosquito breeding resulted in unlivable conditions. Similarly, other tribes inhabiting mountain environments would face springtime hatches of snow pool and floodwater mosquitoes. As the Gold Rush drew miners to California in the 1850’s, the prospectors were quickly introduced to the mosquitoes, their bites and the pathogens they transmit.”

The District’s boundaries comprise almost all of Sutter County and all of the valley floor in Yuba County. Its board of directors is comprised of two members appointed by the Sutter County Board of Supervisors, and one each by the cities of Live Oak, Marysville, Yuba City, and Wheatland, and the Yuba County Board of Supervisors. The District is funded by property taxes.


Today, the District has an array of programs, including providing free mosquito fish, to limit mosquito breeding. They also have an online map showing the location of West Nile activity in birds, mosquitoes and horses.

The District office and yard is located at 701 Bogue Road, Yuba City.

District staff operates and maintains a fleet of surveillance and specialty vehicles used for the surveillance and treatment of mosquitoes and mosquito sources. The District is a member of the Mosquito and Vector Control Association and works in cooperation with such agencies and institutions as: other California Mosquito Abatement and Mosquito and Vector Control Districts; the local Health Departments; County Agricultural Commissioner offices; the University of California labs and research departments and the California Department of Health Services.

The primary goal of the District is to conduct field surveillance to facilitate the detection and control of mosquitoes in order to suppress their populations and prevent the transmission of mosquito-borne diseases. The District also provides consultation and assistance for other vectors of public health importance such as; flies, fleas, ticks, and their associated diseases as resources allow.
