Thermacell E-R236 Rechargeable Mosquito Repeller 36Hr Refill

The Thermacell E-R236 rechargeable mosquito repeller refill delivers 36 hours of continuous protection against mosquitoes and other flying insects. This advanced heat-activated cartridge creates a 15-foot zone of protection without the need for sprays, lotions, or open flames.

What Makes This Different

Unlike traditional DEET-based repellents that require direct skin application, the E-R236 refill uses allethrin, a synthetic copy of a natural repellent found in chrysanthemum flowers. The cartridge activates through the device's heating element, dispersing an odorless vapor that repels mosquitoes at the molecular level. Independent testing shows 98% effectiveness against Aedes, Culex, and Anopheles mosquito species within the protection zone.
