Thermacell Mr450 is a handheld, battery-powered device that uses heat to keep mosquitoes away. The mr450 Thermacell mosquito repeller uses an evaporation system for protection lasting up to 4 hours per mat.

When switched on the Mr450 heats the repellent mats releasing allethrin (a synthetic copy of pyrethrum) into the air. This chemical is found in natural pyrethrum, which is a flower extract used in many insect repellents and has been registered with the EPA as an effective mosquito control product since 1956.

The mr450 contains three mats that can be replaced when they run out. The mr450 works by heating up one of these mats to drive off this spray into the air. When released, allethrin will gradually decline to a residual level within 30 minutes of turning off the mr450, but it should not be present for at least 20 hours after switching on the repellent.

What is a Thermacell mosquito repeller?

The Thermacell mosquito repeller creates a 15 by 23-foot zone in order to repel mosquitoes. The device works by releasing “the repelling agent, allethrin,” into the air that effectively masks both odors and carbon dioxide issued from humans and animals. There is no harmful exposure of pyrethrins or other toxic chemicals which often come with conventional pesticides – no risk! This natural repellent is safe for children, pets, and plants to be around.

Thermacell guarantees 100% effectiveness from any bug-borne illness including the Zika virus when used correctly.
