Until now, mosquito 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.So all you have to do is TURN IT ON...MOSQUITOES GONE.
