Thermacell Fuel-ZoneGuard Mosquito & Multi-Insect Repellent Refills — 96‑Hr (24 Mats, 8 Fuel Cartridges) DEET‑Free Zone Protection

Thermacell Fuel-ZoneGuard Refill pack delivers 96 hours of DEET-free, fuel-powered mosquito and biting insect protection that creates a 15-foot zone around your Thermacell repeller.

When evenings outdoors are interrupted by mosquitoes, black flies or no-see-ums, a reliable zone of protection makes patios, campsites and backyard gatherings far more enjoyable. Thermacell’s Fuel-ZoneGuard refills include repellent mats and butane fuel cartridges designed exclusively for Thermacell fuel-powered repellers. The bundle contains 24 four-hour repellent mats and 8 twelve-hour fuel cartridges — enough material to run the unit for a total of 96 hours — and is formulated to work without direct skin application, smoke, or open flames.

How does this refill pack keep mosquitoes away during outdoor time?

The refill system heats a repellent mat to release a targeted active ingredient that interferes with mosquito sensors, producing a protective radius without needing sprays on skin. Protection begins quickly and reaches full effect within about 15 minutes of operation.

• Creates an EPA-reviewed protection zone up to 15 feet for mosquitoes.
• Also repels black flies and no-see-ums within approximately 10 feet.
• Mat-based, scent-free delivery with no smoke and no open flame required.

What exactly is included and how long will it last?

This pack bundles mats and fuel cartridges sized for Fuel-ZoneGuard repellers so you get complete, compatible supplies in one purchase. Total run time is the sum of all mats and fuel cartridges when used as directed in a Thermacell device.

• 24 repellent mats, each providing roughly four hours of protection.
• 8 butane fuel cartridges, each rated for about twelve hours of heating.
• Combined total of approximately 96 hours of operation from one package.

How do I use the refill components safely and conveniently?

Installation is straightforward and designed for outdoor use: slide a mat under the grill of your repeller, twist in a fuel cartridge, and click the igniter 2–3 times. Turn off the unit when finished and replace mats and cartridges as they are consumed.

• No topical application—nothing applied to skin or clothing.
• Unit heats immediately; expect maximum protection after about 15 minutes.
• Follow all repeller and fuel cartridge safety instructions and use outdoors only.
