SAN DIEGO COUNTY – San Diego County is scheduled to conduct routine aerial larvicide drops four times this month: Aug. 9, 10, 30 and 31 on up to 51 local waterways, including Lake Rancho Viejo, to help stop mosquitoes from potentially spreading diseases like West Nile virus.
The county uses helicopters to drop solid, granular larvicide on hard-to-reach areas of standing water in rivers, streams, ponds and other waterways where mosquitoes can breed. The county conducts the aerial larvicide drops roughly once a month from April through October.
The larvicide does not hurt people or pets but kills mosquito larvae before they can grow into biting mosquitoes.
Report increased mosquito activity, or stagnant, unmaintained swimming pools and other mosquito-breeding sources, as well as dead birds – dead crows, ravens, jays, hawks and owls – to the County Department of Environmental Health and Quality’s Vector Control Program by calling 858-694-2888 or emailing [email protected].
Also report if anyone is being bitten by mosquitoes during daylight hours, or if they find mosquitoes that look like invasive Aedes mosquitoes – small, black with white stripes on legs and backs – by contacting the Vector Control Program at 858-694-2888.
Submitted by the County of San Diego.
