The ThermaCELL® Mosquito Lantern works by heating a mat saturated with mosquito repellent. As the mat is heated the repellent is released into the surrounding area providing an area of protection (about 225 sq. feet).
The lantern utilizes the active ingredient known as allethrin. It belongs to a class of materials called pyrethroids, which are synthetic analogs of pyrethrin, a naturally occurring insecticide found in certain types of chrysanthemum (pyrethrum flowers). Mosquitoes really dislike this material.
The allethrin is contained in the blue mats, and when they are heated it causes the allethrin to "volatilize", which is similar to evaporation. The volatilized allethrin forms a zone of protection around the unit. The amount of active ingredient (0.018 0z. on a mat) that is released is small - not enough to kill mosquitoes, but enough to repel them, keeping your family safe.
