Thermacell MI5 Multi-Insect Repellent Refill 60-Hour

The Thermacell MI5 Multi-Insect Repellent Refill delivers 60 hours of DEET-free, scent-free protection against mosquitoes, black flies, and no-see-ums. Designed as the replacement cartridge set for Thermacell's family of fuel-powered repellers, each refill creates a 15-foot zone of mosquito protection and a 10-foot zone against biting flies and gnats around the user or any outdoor seating area.

Each refill uses Thermacell's proprietary Prallethrin-based repellent mats that, when heated by a compatible Thermacell repeller, disperse a small amount of active ingredient into the air to keep biting insects at bay without sprays, lotions, or open flames. The MI5 refill is compatible with all Thermacell mat-style repellers, making it an easy, drop-in way to keep your existing Thermacell unit ready for backyard, deck, campsite, hunting blind, or patio use.

This listing is for the replacement refill only and does not include a repeller device. Stock up on MI5 refills so your Thermacell is always ready to go when you head outdoors.
