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. From humble beginnings, our team of entomologists, researchers, and outdoor enthusiasts has over 100 years of combined experience fighting mosquitoes.
