Thermacell Mosquito Repellent Refills 60-Hour Pack — 15 Mats & 5 Fuel Cartridges, Scent-Free Protection

Thermacell Mosquito Repellent Refills provide up to 60 hours of scent-free, fuel-powered mosquito protection for a 15-foot radius without spraying on skin.

Keep outdoor time comfortable and bite-free with this refill kit designed for Thermacell fuel-powered repellers (excluding the Backpacker model). The pack contains 15 repellent mats and 5 fuel cartridges that work together to create a consistent protective zone around campsites, patios, fishing spots, and backyard gatherings. Because the system is fuel-powered and mat-based, it delivers continuous protection without DEET, sticky lotions, or airborne sprays directly on people.

How quickly will these refills start protecting me?

The repellent system reaches full effectiveness in about 15 minutes after you install a fuel cartridge and mat. Each mat releases the active repellent gradually and lasts up to about four hours, while fuel cartridges keep the heating element operating for multiple mat cycles. Replacement indicators are simple: mats change color when they're spent, so you know when to swap them out.

• Protection begins in ~15 minutes
• Mats last up to 4 hours each
• Fuel cartridges power several mats before needing replacement
• Mats change color as a visual replacement cue

Will this pack work with my Thermacell device?

These refills are compatible with all Thermacell models that use fuel cartridges and repellent mats, except the Backpacker model. If your repeller is fuel-powered, the mats and cartridges in this pack will fit and perform as expected. Always confirm your device type before purchasing to ensure compatibility.

• Compatible with fuel-powered Thermacell repellers
• Not compatible with the Thermacell Backpacker
• Designed to fit standard Thermacell mat and cartridge housings
• Works with home, campsite, and portable Thermacell units (non-Backpacker)

How do I use and store the refills safely?

Using the refills is a simple swap of a fresh mat and a new fuel cartridge into your Thermacell repeller; follow your device’s instructions for proper seating and ignition. Store unused mats and cartridges in a cool, dry place away from direct sunlight and open flame. These refills are for outdoor use only and should be kept out of reach of children and pets until installed.

• Insert a mat, then a fuel cartridge per device instructions
• Store refills cool and dry, away from heat sources
• Use outdoors only; keep out of children’s reach
• No flame or smoke produced by the repeller during normal operation

What can I expect in terms of scent, safety, and effectiveness?

The repellent mats are formulated to be scent-free during normal use, offering mosquito defense without strong odors on your skin or clothes. Thermacell’s proprietary formula is designed to deter mosquitoes within the device’s coverage area rather than relying on topical application. Independently reviewed for safety and effectiveness, these refills provide a people- and pet-friendly option for outdoor mosquito control when used as directed.

• Unscented operation—no DEET applied to skin
• Designed to repel mosquitoes within the 15-foot zone
• Independently tested and EPA-reviewed for outdoor use
• Easy, low-mess replacement with visual mat color-change indicator

Who is this for? This 60-hour refill pack is ideal for campers, backyard hosts, anglers, and anyone who uses a fuel-powered Thermacell repeller and wants hassle-free, consistent mosquito protection. It’s especially useful for people who prefer not to apply topical insect repellents, for those who want ready stockpiles for outdoor gear, or for households that frequently entertain outside. If you need reliable, scent-free coverage without sprays or lotions, keep a box of these Thermacell refills on hand.
