Want to know how to protect yourself from Zika virus and other mosquito-borne illnesses?

1.  "Tip & Toss" or "Drain & Cover" - Prevent or Reduce Mosquitoes around Your Property.

  • Mosquitoes must have stagnant (standing) water to breed.  Eggs can develop in something as small as a bottle cap of water.
  • By eliminating stagnant water sources, you reduce the number of mosquitoes that could carry illness.
  • Pick up and dispose of any trash or unwanted containers that could hold water.
  • For containers you want to keep, insure that the water is emptied & scrubbed out once weekly (eg, bird baths, flower pot trays, pet bowls, etc).
  • For water you cannot "tip" or "drain," keep it covered or use commercially bought mosquito "dunks" (dissolving larvicide). Follow the directions. 
  • For nuisance sources such as abandoned swimming pools, overgrown yards, illegal dumps, or abandoned tires, call our Environmental Health & Safety Board at 209-8110 (for unincorporated areas of Hamilton County ONLY, City of Chattanooga call 311, or other municipalities call your City Hall).

2.  "Fight the Bite" - Prevent or Reduce Your Chances of Being Bitten by Mosquitoes.

  • Protect yourself from being bitten by mosquitoes by using EPA-approved insect repellents.
  • Keep skin covered with long sleeves and pants, hats, and closed-toed shoes, especially when going to high density mosquito areas (dense vegetation, swampy, low areas, etc.).
  • When using insect repellent and sunscreen, apply sunscreen first, then the repellent.
  • Always follow repellent label directions before using on infants and children. Use no more than 30% DEET on children. Do not use insect repellent containing oil of lemon eucalyptus as the active ingredient on children or infants younger than 3 years.  Do not use insect repellent on babies younger than 2 months of age.
  • Treat clothing and gear with permethrin.  Follow the directions.  Do not apply directly to skin or pets.
  • Keep mosquitoes out of your home.  Use air conditioning if possible, but if you can't, insure screens are in good order and that windows and doors shut, and use mosquito nets over beds during sleep.

  • Know that the Zika virus infection in pregnant women has been associated with poor birth outcomes, particularly microcephaly.
