Product Use

The product works well in outdoor areas where there is minimal air movement, such as decks, yards, and campsites. For best coverage in still air, place the unit close to the ground. This allows repellent to spread over a maximum area.

Thermacell will take 10 to 15 minutes to reach maximum effectiveness. Plan accordingly.

In breezy weather, place the unit upwind of your location so that the repellent is carried by the wind into the area you want to protect.

In normal operation, a small amount of smoke may be visible coming from the device.

Storage & Maintenance

Store your Thermacell in a cool, dry place away from heat sources.  You can put it in a plastic bag to keep dust and dirt out of it.  Always be sure to make sure your Thermacell is working properly if it has been stored for a long period of time.

All Devices

All Devices

Thermacell mosquito appliances and lanterns will not work well at elevations greater than around 2300m (above sea level). Above this altitude, units become difficult to start and run. The lower air density causes the problem.

For best results, start the device and place it outdoors in the area of your intended activity for at least 15 minutes. It needs some time to establish the area of protection.

Rechargeable

  • Check that the device is fully charged
  • Make sure that the top of the device has clicked into place, it will not start unless it is on correctly
  • Make sure that the blue tab has been taken off after purchasing
  • This means that the battery is running low and needs to be recharged
  • Check that there is liquid left in the refill capsule, the device will still turn on and show that it is working even if there is no refill liquid left in the device.
  • Check that the device is fully charged
  • Place the device and power on 15 minutes prior to sitting down
  • Place device at the center of the desired area to be protected
  • Yes, you can still use the device while it is being charged
  • Make sure that there is a refill capsule in the device
  • Occasionally condensation can occur. Wipe clean with a cloth or paper towel
  • Press and HOLD the power button for 2 seconds until you hear the descending chime and all illumination turns off
  • Remove the top and the unit will automatically turn off

Fuel Powered

The fuel supply may be empty. Look at the fuel gauge on the bottom side of the unit. Turn the unit off, replace the butane cartridge, and start it as shown in the directions. Next, turn the on/off switch to the on position and let the butane gas flow for 2 minutes before hitting the start button. This will purge the appliance and often corrects the problem. If the appliance still does not function correctly after trying the above steps, you may return it for a full refund.

Check to be sure that the pad has blue colour left. If not, replace the pad with a fresh one. If the wind is blowing, place the unit so that the wind blows over it first, then the area you want to protect. That way, the wind will carry the repellent to where you want it.

Ensure the Gas Canister is threaded in squarely and properly engaged within the unit. If in doubt, remove and reinsert canister.
