This chemical, also called BioUD, comes from tomatoes. It’s available in BiteBlocker, and some studies say it works as well as products with 30% DEET.
Foggers and sprays can temporarily banish mosquitoes from outdoor areas — foggers can last for hours, sprays for days. But the chemicals can be harmful if you, or your pets, come into contact with them while they’re still wet or in the air. Keep windows closed during treatment, and stay out of your yard until everything is dry. Bees and butterflies can also be wiped out, so it’s best to avoid treating the places they hang out.
If mosquitoes can’t get to skin, they can’t bite it. When possible, wear long sleeves, pants, and a hat when you know you’ll be in a mosquito-infested area. Tuck your shirttail into your pants and your pant legs into your socks for maximum bite blockage.
Stop mosquitoes before they hatch by ridding your yard of standing water, their favorite breeding ground. It doesn’t take much moisture for them to set up shop — even an overturned Frisbee filled with rainwater is enough. Drain pooled water where you can, and clear out anything that might collect it, like tires or pots.
