For the backyard and beyond, Thermacell Max Life Refill Mats and Cartridges keep your Patio Shields, Lanterns, and Torches fueled for the long haul, no batteries or cords needed. Max Life Mats last 3X longer than original Thermacell mats, so you replace mats less frequently and run it overnight. Always be prepared by keeping an extra cartridge and mat in your tent, backpack, garage, or tackle box, ready when you need it. Mosquitoes are no small problem - they can ruin a good time with painful bites, bothersome buzzing, and days of itching afterward. 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. Our mission at Thermacell is to change the way the world fights mosquitoes and we’ve been doing it for over 20 years. Headquartered outside Boston with distribution centers in Georgia, we’re leading the way with better 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.
