Contra Costa County encompasses some of the most diverse environments found in one area. This wide range of environments makes our county one of the most desirable places to live in Northern California. The Contra Costa Mosquito and Vector Control District plays a vital role in maintaining this environment while protecting the residents from insects and animals that can carry disease. The District helps to ensure Contra Costa County remains a great place to live, where people can enjoy life outdoors.
The citizens of Contra Costa County, together with several waterfront industries, formed a committee in 1926 to address the need for mosquito control. In 1926, Noble Stover responded to requests from Contra Costa County and directed – first operations of Contra Costa Mosquito Abatement District #1 (CCMAD #1). The purpose of the District was to control marsh mosquitoes in north central Contra Costa County. CCMAD #1 was formed and work began on April 15. 1927. The District. With two employees, began various engineering projects near the cities of Martinez, Concord, and Pittsburg. Much of the work was contracted out to dredging and construction companies. Mr. Stover was a pioneer in drainage and engineering methods, which were his primary approaches to controlling salt marsh mosquitoes. Many of those early projects still exist and are functional now more than 80 years later. Noble Stover served as manager/engineer for CCMAD #1 until his death on September 17, 1935. Ernest Campbell, who had worked for the District since its conception, was appointed manager/engineer by the Board of Trustees upon the death of Noble Stover.
Until 1941 the District’s jurisdiction only covered the waterfront and marsh areas from Martinez to Antioch. On November 25, 1941 the communities of Saranap, Danville, and the City of Walnut Creek petitioned the CCMAD#1 Board of Trustees, requesting annexation into the District. Annexation took place On December 19, 1941. In November 1943, CCMAD #1 annexed the area comprising – Lafayette and Orinda School Districts upon their request. Oak Grove School District was annexed in July 1946 upon their request.
The Contra Costa Mosquito & Vector Control District is dedicated to the health and welfare of the county's more than 1 million residents covering 736 square miles. In fact, we've been protecting public health since 1927 when residents formed the District. Funded through tax dollars, the District offers free services for mosquitoes, rats and mice, ground-nesting yellow jackets, ticks, and skunks. Our trained and certified employees work daily to reduce the risk of diseases spread by insects and animals by controlling them in a responsible, environmentally-conscious manner. It's all part of our Integrated Vector Management program where we use the most efficient and effective state-of-the-art protocols and products. All products are registered with the Environmental Protection Agency.
