Fuel-powered refill pack with six 4-hour repellent mats and two 12-hour fuel cartridges. Creates a 15-foot protection zone without DEET, smoke, or flames. EPA-reviewed formula repels mosquitoes including West Nile and Zika vectors.
The Thermacell Original Refill Pack R2 delivers reliable mosquito protection for outdoor enthusiasts who prefer not to apply insect repellent directly to their skin.
This refill system uses a proprietary allethrin-based formula that creates an effective 15-foot protection zone around your position. The fuel-powered design requires no flames, produces no smoke, and generates no offensive odors—making it ideal for hunting camps, fishing trips, backyard gatherings, and camping.
Each repellent mat provides up to 4 hours of continuous protection, while each fuel cartridge lasts up to 12 hours. The formula has been independently tested and EPA-reviewed for both safety and effectiveness. It repels mosquitoes that may transmit serious illnesses including West Nile Virus and Zika Virus.
These refills are designed for use with Thermacell fuel-powered repellers, lanterns, and torches. This is an outdoor-use-only product suitable for people and pets.
No DEET. No skin applications. No flames. Just effective mosquito control.
