The Contra Costa Mosquito & Vector Control District utilizes an integrated vector management program which means we use a variety of protocols for controlling mosquitoes. These protocols include public education, physical control such as managing vector habitat, biological control such as mosquitofish, and chemical control such as pesticides.

The majority of the District’s mosquito control is completed when mosquitoes are still in their aquatic form, in their water source. Once mosquitoes emerge from the water as adults, the only effective method to control them is by adult mosquito control. We use only those products registered with the Environmental Protection Agency (EPA) for the use of mosquito control and protecting public health. They are applied by our trained and certified technicians.
