Ways to protect yourself from mosquitoes and West Nile virus: 
Reduce outdoor exposure to mosquitoes:
  • Limit outdoor activities during peak mosquito activity (dawn and dusk).
  • Properly use mosquito repellents containing DEET, picaridin, IR3535 or oil of lemon eucalyptus (always read the label carefully).
  • Wear protective clothing such as long sleeves and long pants.

Reduce indoor exposure to mosquitoes:

  • Keep doors and windows closed whenever possible.
  • Check and maintain all window and door screens.

Prevent mosquitoes from breeding near your home:

  • Flip, dump or drain all temporary sources of standing water.
  • Check septic tank lids to ensure a tight seal and repair any visible cracks.
  • Screen septic tank vent pipes using a fine mesh screen.
  • Eliminate standing water in rain barrels, old tires, buckets, kiddie pools or any other item that can hold water for more than a week.

West Nile virus is a mosquito-borne disease that is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread the disease to humans and other animals.
