Mosquitos are no small problem - they can ruin a good time with painful bites, bothersome buzzing, and days of itching afterwards. Until now, sprays, lotions, torches, DEET and citronella have been the only options for fighting mosquitoes. We started Thermacell because we wanted a better way to fight mosquitoes. From humble beginnings, our team of entomologists, researchers, and outdoor enthusiasts has over 100 years of combined experience fighting mosquitoes. Enter Thermacell. For the backyard and beyond, Thermacell Refills keep your Patio Shields, Lanterns, Torches, and other fuel-powered Thermacell Repellers fueled for the long haul, no batteries or cords needed. Always be prepared by keeping extra cartridges and mats in your tent, backpack, garage, or tackle box ready when you need it. At Thermacell, our mission is to change the way the world fights mosquitoes, and we've been doing it for over 20 years. Headquartered outside Boston, US, we're leading the way with better, worry-free, more environmentally friendly solutions to biting insects. With global distribution in 30+ countries and tens of millions of repellers sold, more and more people around the world count on Thermacell to make outdoor time even better.
