Thermacell works by heating a mosquito repellent chemical and releasing it into the air. This creates an invisible protection zone around the user. Mosquitoes avoid the area because the vapor blocks their ability to find people. The Eucalyptus Citriodiora oil is nature's most effective insect repellent. It is a naturally sourced active ingredient derived from the oil of the Eucalyptus Citriodora tree which is a natural and renewable resource grown in several parts of the world. Citriodiol has passed the most rigorous safety and efficacy tests.
