The agricultural areas, rice fields, and marshes of West Placer County are scheduled for an aerial larvicide treatment tonight, June 25th.
Larval treatments involve an EPA-registered biorational mosquito larvicide applied by a low-flying aircraft to prevent the emergence of adult mosquitoes and reduce the risk of mosquito-transmitted diseases. Treatments will occur during the daylight hours, most commonly in the early morning through the early afternoon.
Placer Mosquito and Vector Control District conducts aerial larvicide and adulticide applications to manage mosquito populations and protect public health in Placer County. Aerial applications are an important part of our comprehensive, integrated vector management program.
Aircraft often fly over Elverta to allow for the prevailing winds to carry the spray into Placer County.
Chemical control involves using natural, microbial, or synthetic insecticides registered for public health use by the Environmental Protection Agency and the California Department of Pesticide Regulation to manage mosquitoes and yellowjackets. In California, large-scale insecticide treatments for tick control are generally unnecessary and ineffective. Chemical control can be utilized independently or in conjunction with biological or physical control methods to reduce mosquito populations.
The District ensures that all public health insecticides are applied according to their labels and follow best practices. Depending on the operation, target, and timing, insecticides may be applied using hand equipment, ground vehicles, or manned and unmanned aircraft. Chemical control is also employed in emergency situations to quickly disrupt or stop the transmission of mosquito-borne diseases to humans. These treatments are carried out by trained and state-certified District technicians.
