Mosquito bite prevention is key, because there is no cure for West Nile virus. Residents can follow the 3 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.
