ThermaCELL Mosquito Repellent
Repels mosquitoes, midges and black flies.
ThermaCELL® uses revolutionary, patented technology to dispense a small amount of repellent into the air over a long period of time.
ThermaCELL® is powered by a butane cartridge which provides the cordless, portable heat necessary to operate the device (batteries are not needed).
The heat is directed to a metal grill. A mat saturated with Allethrin, a copy of a naturally occurring insecticide found in chrysanthemum flowers, is placed on top of the metal grill.
The heat generated by the butane cartridge vaporizes the repellent allowing it to rise into the air, creating a 15 x 15 ft (225 sq ft) mosquito and midge-free-zone in minutes.
