Thermacell R4 Mosquito Repellent Refill Value Pack

Thermacell R4 Mosquito Repellent Refill Value Pack

The Thermacell R4 Refill Value Pack delivers effective, hassle-free mosquito protection for outdoor enthusiasts who demand reliability without compromise. This refill set is designed to keep biting insects at bay while you focus on what matters—hunting, fishing, camping, or simply enjoying your backyard.

How It Works

Thermacell uses heat-activated technology to create a 15-foot zone of protection around your position. The system requires no batteries, cords, or open flames. Simply insert a fuel cartridge, add a repellent mat, and let the device work. The active ingredient is allethrin, a synthetic compound modeled after a naturally occurring repellent found in chrysanthemum flowers.

What's Included

• 12 repellent mats (4 hours of protection each)
• 4 fuel cartridges (12 hours of protection each)
• Total coverage: up to 48 hours of mosquito defense

Key Features

• DEET-free formula — safe for families, children, and pets
• Scent-free operation — no smoke, flames, or harsh odors
• Color-changing mats — indicate when replacement is needed
• Plant-inspired technology — allethrin is derived from natural plant compounds
• EPA-tested — independently reviewed for safety and effectiveness
• Compatible with all fuel-powered Thermacell repellers (except Backpacker model)

Ideal For
