ADULT MOSQUITO TREATMENT INFORMATION
There are currently no adult mosquito treatments scheduled in San Diego County.
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 an ultra-low-volume insecticide spray (ULV) and other treatments to reduce the number of infected adult mosquitoes. Insecticides that may be used for ULV adult mosquito treatment include Pyrenone 25-5. Truck mounted or backpack sprayers are used to deliver the ULV. Residents in affected areas will be notified at least 1 day prior to ULV treatment.
