Mosquitos 

Spring Valley & La Presa Residents should report mosquito activity or stagnant water sources including green swimming pools and other mosquito breeding sources, as well as dead birds (crows, ravens, hawks & owls) to the County Vector Control Program at 858-694-2888 or emailing vector@sdcounty.ca.gov

Female mosquitoes lay their eggs in standing water sources. When the eggs hatch, they become mosquito larvae. Larvae can mature into biting adult mosquitoes in as few as 5 days. Under ideal conditions, mosquitoes can complete their life cycle from egg to adult in as few as 7 days.
