Ways to protect yourself and your family from mosquito bites.

Drain Standing Water
Mosquitoes lay their eggs in standing water so limit the number of places around your home for mosquitoes to breed by getting rid of items that hold water. Bird baths, wheel barrels and puddles are common mosquito breeding grounds.

Install or Repair Screens
Some mosquitoes like to come indoors. Keep them outside by having well-fitting screens on windows and doors.

Avoid Bites
  • Apply insect repellant containing DEET (Look for N,N-diethyl-meta-toluamide) to exposed skin when you go outdoors. Even a short time being outdoors can be long enough to get a mosquito bite. Do not spray repellent containing DEET on the skin under your clothing.
  • Use clothing to help reduce mosquito bites. When possible, wear long-sleeves, long pants and socks when outdoors. Mosquitoes may bite through thin clothing, so spraying clothes with repellent containing permethrin or DEET will give extra protection. Don't apply repellents containing permethrin directly to skin.
  • Be aware of peak mosquito hours. The hours from dusk to dawn are peak mosquito biting times. Take extra care to use repellent and protective clothing during evening and early morning or consider avoiding outdoor activities during these times.
