Thermacell C-4 Fuel Cartridge Refill, 4-Pack

The Thermacell C-4 Fuel Cartridge Refill 4-Pack effectively repels mosquitoes for up to 48 hours by creating a 15-foot zone of protection when used with Thermacell devices and Thermacell Repellent Mats. Use this Fuel-only refill for when you have spare Thermacell Repellent Mats. Heat produced by a Thermacell Fuel Cartridge is directed to a small mat infused with the repellent Allethrin, a synthetic version of a naturally occurring repellent found in chrysanthemum flowers. Heat disperses the repellent creating the 15-foot zone of protection. Thermacell protects millions of people from mosquitoes with no messy sprays or lotions, no scent, no noise, no DEET, and no open flames. For best results, use on days with light or no wind (bugs are at their worst on these days), and allow 10-15 minutes to form a complete zone of protection around the unit. Thermacell products are safe, effective, and come with a 100% Satisfaction Guarantee. With Thermacell, Turn it on… Mosquitoes GONE!
