West Nile virus is spread through the bite of an infected mosquito. GLACVCD would like to remind parents that mosquitoes are most active between dusk and dawn. Children participating in afterschool activities can protect themselves from mosquito bites by using Center for Disease Control approved insect repellent and wearing long-sleeve shirts and pants.

Residents can follow the Three D’s of West Nile virus prevention to protect themselves and their families:

Dump/Drain: Eliminate standing water on your property because that’s where mosquitoes breed.

Dusk/Dawn: Avoid outdoor activities when mosquitoes are most active.

Defend: Wear CDC approved insect repellent and long-sleeve shirts and pants when outdoors. Use properly fitted and well maintained screens on windows and doors around your home.

Contact the Greater Los Angeles County Vector Control District at (562) 944-9656 or visit to report a green pool or to submit a service request. For additional West Nile virus information, visit or call 1-877-WNV BIRD to report a dead bird or squirrel.
