Adult Mosquito Control Information

The Vector Control Program (VCP) monitors mosquito-related public health risks throughout the County. If an elevated public health risk exists that cannot be reduced by other means, such as eliminating mosquito breeding or preventing larval growth, then the VCP may use adult mosquito control treatments to reduce the number of infected adult mosquitoes. Depending on the situation, these adulticides may be applied with hand-held, backpack, portable, and/or truck mounted equipment by skilled vector control technicians certified by the California Department of Public Health. Larvicides may also be used in situations where mosquito breeding is detected. Every attempt will be made to contact residents in affected areas at least 24 hours prior to treatment.
