How can I protect myself?

ADHS says the best way to protect yourself from mosquito bites is to use an EPA-registered repellent, wear long-sleeved shirts and long pants, and have door and window screens installed to keep the insect out of your home.

How do I keep them away from my home?

The best way to keep mosquitoes away from your home is to cover areas that can hold water. "Mosquitoes lay their eggs near water. Some species only need small amounts of water, such as the amount that can accumulate in flower pots, buckets, bird baths, and children’s toys," ADHS says.

  • At least once a week, empty and scrub, toss or cover any items that can hold water.
  • Keep your yard clean and clear from debris, to reduce potential breeding sites.
  • If you cannot dump the water (and it’s not drinking water), consider treating it with larvicides, like Mosquito Dunks.
