When does the Sacramento-Yolo Mosquito and Vector Control District use chemical mosquito control?

A. Chemical control is the use of specific chemical compounds (insecticides) that reduce adult and immature mosquitoes. It is applied when biological and physical control methods are unable to maintain mosquito numbers below a level that is considered tolerable or when emergency control measures are needed to rapidly disrupt or terminate the transmission of disease to humans. Larvicides target mosquito larvae and pupae. Adulticides are insecticides that reduce adult mosquito populations. All products are registered with the California Environmental Protection Agency (EPA) and are applied by trained and state-certified technicians.  more
