All Thermacell Mosquito Repellers, Mosquito Repellent Lanterns, and Mosquito Repellent Torches work the same way and all are able to use any Thermacell repellent mats and refill cartridges. Thermacell repellent devices repel mosquitoes by creating a 15ft x 15ft zone of area repellent. This repellent, allethrin, is a synthetic copy of a natural repellent found in chrysanthemum plants. Thermacell repellent devices are powered by a butane cartridge. Butane provides the cordless, portable heat that activates the devices. The heat generated by the butane cartridge is directed to a metal grill. A small mat saturated with repellent is inserted on top of the metal grill. Heat disperses the repellent from the mat into the air, creating the zone of protection.
