ThermaCELL is a portable, battery-less, non-toxic device that dispenses a small amount of heated mosquito repellent into the air over a long period of time. This device is powered by a butane cartridge which provides the cordless, portable heat necessary to vaporize the repellant, which mimics naturally occurring insecticide. The repellant creates an area of 15 x 15 ft (225 sq ft) of protection against mosquitoes. The product promises to keep 98% of biting insects at a distance.
This device was developed under a cooperative research and development agreement between The Schawbel Corporation and Walter Reed Army Institute of Research.
ThermaCELL was tested by the United States Army and it was used by the U.S. Army in Iraq, Kuwait and Afghanistan.
