Mosquitoes are attracted to lactic acid, a chemical found in sweat, so as you and your family become active, be sure to use OFF! Active repellent. It provides hours of protection for your active lifestyle. Protects against mosquitoes, biting flies, gnats, ticks, chiggers, and fleas. It works on skin and clothing and is perfect for running, hiking, playing, and outdoor activities. Product label may vary.
Says its sweat resistant and it sure is! My daughter plays softball at a park and I think there's a creek nearby or something? The mosquitoes are BAD, they've complained other sprays wipe right off and mosquitoes still bite through their socks. I turned to this one and haven't turned back. It stays on them for a 3+ hour nights of playing around. Recommended for outdoor athletes!
