Tips to Protect Yourself

Vector Services & Information

The best defense against disease transmission is being proactive and taking precautions to protect from mosquito bites. Follow these simple steps to protect yourself and your family:

  • Avoid outdoor activities between dusk and dawn when mosquitoes are most active.
  • Wear long sleeve shirts and pants when engaging in outdoor activities during these hours.
  • Apply approved insect repellents containing active ingredients such as DEET, Picaridin, or oil of lemon eucalyptus.
  • Keep tight-fitting screens on doors and windows to prevent mosquitoes from entering your home.
  • Eliminate all sources of standing water around your home and property and properly maintain ornamental ponds, pools, and spas.
  • Request FREE mosquitofish from your local vector control district for placement in out-of-order swimming pools, spas, and ponds to control mosquito breeding.
  • Contact the Greater Los Angeles County Vector Control District at (562)944-9656 or online HERE to report any significant mosquito problems in your neighborhood. The District strongly encourages you to report any mosquito activity near vacant or foreclosed homes and abandoned swimming pools in your neighborhood.

The public is encouraged to report dead birds to help with West Nile virus surveillance and control efforts, as birds play an important role in maintaining and spreading the virus. The CA Department of Public Health's toll-free hotline is 877-WNV BIRD or visit on-line at:
