If you have ever spent any time outside in the summer, you know how quickly deer flies can ruin your day. Conventional insect repellents like DEET work on mosquitoes and other bugs by disrupting their ability to sense carbon dioxide. But deer flies are also attracted by the movement, warmth, and the size of warm-blooded animals, rendering conventional repellents ineffective and making active humans a perfect target for these bloodsucking pests. Foggy Mountain® Deer Fly Stoppers make outdoor recreation pleasant again. Simply apply one of the adhesive strips to the back of a hat and you’re good to go on that run, hike, walk or other outdoor summer activity. The flies can’t resist the flesh-colored deer fly traps – they land, they’re stuck, they’re done. Take back your outdoor fun with Deer Fly Stoppers!
