DEET is a common ingredient in insect repellents, and sprays with DEET are probably the way to go if you know you’re at risk of bites, Piliang said. Despite the controversy over the health effects of DEET, a 2014 review by the Environmental Protection Agency re-concluded that normal use of DEET products does not pose a risk to one’s health, including children, pregnant women and breastfeeding women.
“DEET is the most effective,” Piliang said. “If you are going to be in a mosquito-prone place, knowing that they carry disease, it is your best bet. Take a shower later to wash it off, and put on just a little bit.” Always read the directions on a spray before using it, and help children apply products by following the U.S. Centers for Disease Control and Prevention guidelines.
And while you may have heard that candles containing natural repellents like citronella oil can be useful, there is no research to support it yet. Instead, keep the fan on or hang out in a breezy area.
“Mosquitoes can’t get around very much,” especially in wind, Piliang said. “You can run a fan to keep air moving.”
If you do end up with a bite, you may or may not be bothered. “This all depends on how allergic you are to the chemicals in the saliva of the mosquito, and that can vary based on the type of the mosquito or how reactive you and your skin are to things in the environment,” Piliang said.
If it is itchy, the worst possible thing you can do is scratch it.
