After releasing the list of worst cities in the country, Orkin has recommended some tips to help protect against mosquito bites.

Orkin recommended that before going outside, people should apply an EPA-registered insect repellent to prevent from mosquito bite. One can use candles or torches around their yard, Orkin added. It also said that people should prefer wearing long sleeves and pants outside from dawn to dusk.

Orkin recommended, “Empty any standing water from bird baths, flower planters as well as toys and playground equipment outside the home to help prevent water from collecting. Mosquitoes only need a small amount of water – just a few inches – to breed.” It also suggested people to eliminate standing water inside the home.
