ThermaCell Moquito Repellent Refils

Make sure your Therma CELL Mosquito Repellent keeps protecting you from those pesky bugs. Pack consists of 1 Terma Cell Butane cartridge and 3 Therma Cell Mosquito Repellent Mats. Don't run out of refills! Product Features All Therma CELL models use the same refills. Each cartridge lasts up to 12 hours, and each mat lasts up to 4 hours. Refills can be stored for long periods of time. Cartridges and mats don't need to be used all at one time. For example, one could use the cartridge and mat for an hour a day. Simply turn the unit off and restart when ready. If time between use will be more than a 1 week, store the mat in a dry, dark place. The repellent, allethrin, is a synthetic analogue (chemical copy) of a naturally occurring insecticide, pyrethrin, found in the pyrethrum flower, a member of the chrysanthemum family.
