Vector Control


It is critical that residents remove all standing water on their property to prevent mosquito production. Mosquitoes lay their eggs on stagnant water such as neglected pools, buckets, miscellaneous containers, puddles, and ponds. Eggs can hatch and develop into biting adults in four to seven days.

Dead Birds are often the first indication of West Nile Virus activity in a given area. Residents are encouraged to help identify WNV “hot spots” by reporting dead birds to the WNV Hotline at 877.968.2473 or online at | California West Nile Virus Website. Residents can protect themselves from mosquito bites by using mosquito repellents, wearing long-sleeve shirts and long pants when outdoors between dusk and dawn, and ensuring windows and doors are properly screened to keep mosquitoes out.

Vacant homes with inoperable pools pose a very real risk to neighborhoods. One ‘green’ pool can breed thousands of mosquitoes per week that affect properties for blocks around. Residents are encouraged to report hazardous conditions to the San Gabriel Valley Mosquito and Vector Control District at 626.814.9466 or
