Thermacell Fuel-ZoneGuard Backpacker Mosquito Repellent Mat Refills, 48-Hr DEET-Free 12-Pack

Thermacell Fuel-ZoneGuard Backpacker Mosquito Repellent Mat Refills are DEET-free mat cartridges that deliver up to 48 hours of protection for a 15-foot mosquito-free zone when used with compatible Backpacker repellers.

These replacement mats are made specifically for Thermacell Fuel-ZoneGuard Backpacker devices and contain a proprietary repellent formulation designed to deter mosquitoes without applying lotions or sprays to skin. Each pack includes twelve 4-hour mats (totaling 48 hours) engineered to heat and disperse the active ingredients evenly, creating a scent-free, smoke-free protection area. They are easy to install and intended for outdoor use with Thermacell Backpacker repellers only.

How long does a single mat last and how much coverage does it create?

Each mat provides roughly four hours of continuous repellent action when the Backpacker device is operating at normal temperature. When used as directed, the mat’s heated formula disperses to form a roughly 15-foot radius protective zone around the device, helping reduce mosquito presence in that area.

• One mat = ~4 hours of protection.
• 12 mats included = approximately 48 hours total.
• Effective zone size: about 15 feet in radius.

Are these mats safe for people and pets, and do they contain DEET?

Thermacell Fuel-ZoneGuard mats are DEET-free and designed for outdoor use; they have been independently tested and reviewed for safety and effectiveness with Thermacell repellers. Because the mats release repellent through a heated diffusion process, they avoid skin application and minimize direct contact.

• DEET-free formulation.
• For outdoor use only; keep out of reach of children and pets when handling.
• Independently tested and EPA reviewed for repeller use.

How do I install and use these replacement mats with my Backpacker repeller?

Installation is straightforward: slide a mat under the grill of the Backpacker unit, secure the fuel canister, and click the device 2–3 times to start heating. The repeller reaches maximum dispersion in about 15 minutes; switch it off when finished and replace mats as needed.

• Slide mat under the unit’s grill before inserting fuel canister.
• Twist fuel canister into place; click 2–3 times to activate heating.
• Allow ~15 minutes for full protection; replace mats after four hours of use.

Will these mats work with other Thermacell repellers or non-Thermacell units?

These mats are formulated for compatibility with all Thermacell Fuel-ZoneGuard Backpacker repellers and are scientifically validated for use with Thermacell devices. They are not guaranteed to function correctly in non-compatible or third-party units.

• Compatible with all Thermacell Fuel-ZoneGuard Backpacker models.
• Only genuine Thermacell refills are proven to work with Thermacell repellers.
• Packaging may vary but product fit and performance remain consistent.

Who is this for? These refill mats are ideal for campers, hikers, patio hosts, and outdoor workers who already own a Thermacell Fuel-ZoneGuard Backpacker repeller and want a convenient, DEET-free substitute to keep mosquitoes away. If you prefer a hands-off, scent-free approach to creating a small protective perimeter without sprays or lotions, this 12-pack gives you multiple outings’ worth of coverage and straightforward upkeep. For any performance concerns, Thermacell offers customer support for repair, replacement, or refund.
