Mosquitoes are no small problem - they can ruin a good time with painful bites, bothersome buzzing, and days of afterward. Until now, DEET bug sprays, lotions, torches, 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 repelling mosquitoes, and for 20 years our mission at Thermacell has been to change the way the world fights mosquitoes. Headquartered outside of 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 insect repellents sold, more and more people around the world count on Thermacell to make outdoor activities even better. * Thermacell Patio Shield Mosquito Repeller creates a 15-foot zone of protection against mosquitoes * Heat-activated technology powered by a safe and compact fuel cartridge that emits scent-free mosquito repellent to drive away mosquitoes * No mess, easy refill with included unscented mosquito repellent mats that last up to 4 hours each and change color when it's time to replace * Repels mosquitoes without DEET bug sprays or lotions on your skin, smoke, flames, or strong scents, like citronella, with maximum protection in 15 minutes and no cords or batteries needed * People- and pet-friendly, synthetic allethrin formula inspired by natural repellent extracts and independently tested and EPA-reviewed for safety and effectiveness * Keep enjoying outdoor activities with this sleek mosquito repeller on the porch, by the pool, while camping, at the lake, and more * Automatic 1-year warranty included, with 2-year extended warranty available with registration, backed by the Thermacell Satisfaction Guarantee * Includes one mosquito repeller, one 12-hour fuel cartridge, and three 4-hour repellent mats
