Mosquitoes are a significant issue since their itchy bites, obtrusive buzzing, and painful bites may ruin a good time. Until recently, the only methods for battling mosquitoes were sprays, lotions, torches, DEET, and citronella. We invented Thermacell because we wanted a more effective method of controlling mosquitoes. Our team of entomologists, researchers, and outdoor lovers has over 100 years of combined expertise against mosquitoes and comes from modest origins. Thermacell has been working for more than 20 years to transform the way people combat mosquitoes. We're setting the standard for better solutions to biting insects, with a headquarters outside of Boston and distribution facilities in Georgia. More and more people across the world rely on Thermacell to improve their outdoor time thanks to its widespread distribution in more than 30 countries and the sale of tens of millions of repellers.
