West Nile Virus

West Nile Virus (WNV) is spread by infected mosquitoes, and can cause serious, life-altering and even fatal disease. Enjoy the warm weather, but remember to protect yourself and your family against WNV infection.

Prevention
  • Be aware that many mosquitoes are most active at dusk and dawn.
  • Change the water in pet dishes daily.
  • Drill holes in tire swings so water drains out.
  • Get rid of mosquito breeding sites by emptying standing water from around your home.
  • Keep children's wading pools empty and on their sides when they aren't being used.
  • Make sure you have intact screens on your windows and doors to keep mosquitoes out.
  • Replace the water in bird baths weekly.
  • Use insect repellent and wear long sleeves and pants when outdoors at these times or consider staying indoors during these hours.
  • When you are outdoors, use insect repellent containing an EPA-registered active ingredient. Follow the directions on the package.
