ThermaCell Grey Mosquito Repellent Appliance

ThermaCell Silver Mosquito Repellent Appliance is the only butane-operated mosquito repellent system that is also a cover scent, offering concealment in the spring and early fall when mosquitoes are at their worst. This system creates a 15' x 15' area of protection that is up to 98% effective against mosquitoes and other biting insects.

The ThermaCell Silver Appliance operates on a single butane cartridge, that heats a mat and releases allethrin, a synthetic copy of a naturally occurring insect repellent. Each mat contains enough repellent for four hours of protection, and each butane cartridge will operate the unit for 12 hours.

ThermaCELL appliances are for outdoor use only.

Note: Must be shipped via ground, no air shipments and NO SHIPPING TO Hawaii, Alaska, or Puerto Rico, sorry.

ThermaCELL Mosquito Repellent Appliance Instructions

1. Remove one ThermaCELL Mosquito Repellent mat from wrapper. One mat lasts up to 4 hours. Mat turns from pale blue to white when active ingredient has been exhausted.


2. Make sure the 'On/Off' switch on the appliance is in the 'Off' position. Insert the mat under the appliance's black grill. To change mats, slide the 'On/Off' switch to 'Off' and allow the appliance to cool completely. Push the used mat out by inserting a fresh one.


3. Remove the appliance cover and butane cartridge cap.


4. Screw the cartridge into the opening of the appliance. Make sure the cartridge is fully inserted by turning it clockwise until it stops. Replace the appliance cover. One ThermaCell butane cartridge lasts 8 to 12 hours. If your appliance fails to heat, it may be out of fuel. Check the fuel level by holding the appliance vertically and looking at the fuel gauge on the bottom. You can see the amount of butane in the cartridge. Replace if empty.


5. Slide the 'On/Off'switch to the 'On' position; the butane gas will begin to flow.


6. Wait approximately 5-10 seconds then depress the start button three to five times in rapid succession.


7. To verify the appliance is operating, pick it up and check the lens on the end of the appliance. The light at the end of the appliance glows when the appliance is heating. If the light is not glowing, check to make sure the appliance is 'On' and the cartridge is completely screwed into place; then once again depress the start button three to five times in rapid succession. Check to make sure the light is glowing.


8. Place the appliance on a flat, stable area with the grill side facing up. Do not touch the grill; it will be hot after a couple of minutes. When finished using the appliance, slide the 'On/Off' switch to the 'Off' position, and allow the appliance to cool completely. Appliance is now ready for storage.
