Fuel-ZoneGuard Extreme Mosquito Repeller (MR300)

How large of an area does one fuel powered device protect?:

Thermacell Fuel-Powered Repellers provide effective mosquito repellency for an area up to 15 x 15 feet (225 square feet), the size of an average deck or patio. You may use more devices to protect larger areas.

How do I know the fuel powered device is on and working?:

An orange glow in the view-finder, often on the top of the device, indicates that the Thermacell Repeller is on.

Can I stop and start the unit or do I have to use it all at once?:

You can turn the unit on and off at will. Please allow 10 to 15 minutes for Thermacell to reach maximum effectiveness. You can use a Repellent Mat until it turns completely white.

Can I go on an airplane or fly with my Thermacell?:

You cannot bring Thermacell Fuel Cartridges on a passenger aircraft. We typically suggest bringing your Thermacell Repeller and the mats but purchase the Fuel Cartridges at your destination. Our rechargeable repellers (Radius, E55 Rechargeable, E90, EX series) and Backpacker can be taken on aircraft. Thermacell products are sold internationally and throughout United States and Canada.

Can the repeller be used indoors, in a tent, or in a covered porch?:

Thermacell products are for outdoor use only and should not be used in enclosed spaces. You should always follow label-use instructions.

What is the difference between Fuel powered and battery powered repellers?:

Our devices have a built-in li-ion battery for power and use a single liquid-repellent cartridge. This differs from fuel-powered repellers, which heat and activate the repellent mat using a fuel cartridge. Rechargeable products are also TSA-compliant, so you can bring them on an airplane. When purchasing refills, be sure you are ordering the correct type of refill for your repeller. Battery-powered repellers use the "rechargeable" refills.

What are the main ingredients in your products?:

Our products contain active ingredients that repel mosquitos and inactive ingredients that assist with their release into the air. Our fuel-powered repellent mats use allethrin as the repellent active ingredient.
