Thermacell - Multi-Insect Repellent Refills

For your yard and beyond, Thermacell Multi-Insect Repellent Refills keep your patio repellents, lanterns, and handheld devices running for long periods of time—without batteries or cords. Compatible with all gas-powered Thermacell repellents (except the Backpacker). The first and only EPA-registered area repellent for black flies and gnats, these refills protect against mosquitoes, black flies, and gnats. Not suitable for house flies.

Thermacell Multi-Insect Repellent creates a 4.5-meter zone of protection against mosquitoes and a 3-meter zone of protection against black flies and midges. Ideal for camping, in your garden, or whenever you need protection.

Proven to repel only mosquitoes, black flies, and midges—no DEET spray or lotion on skin. No smoke, flames, or strong odors like citronella. Get maximum protection in 15 minutes. Thermacell portable fuel-powered devices require no cords or batteries. They emit a fragrance-free repellent that keeps mosquitoes, black flies, and midges away. Powered by a compact, safe 12-hour fuel cartridge (included).

Our synthetic prallethrin formula is inspired by repellent extracts found in plants. Independently tested and approved by the EPA for safety and effectiveness. Safe for people and pets.
