Introducing from Thermacell the MR300 Portable Mosquito Repeller, this compact repeller is perfect for home and garden use as well offering mosquito protection at the campsite. With thanks to its flat design the MR300 can be placed on any table-top and in use this silent and convenient flying insect repellent provides a 15-foot zone protection.

Thermacell Repellers use a single butane cartridge that heats up a repellent mat once up to temperature the mat releases the repellent allethrin and creates a 15ft x 15ft zone of protection against the mosquitoes. The butane provides you with a cordless device that makes the unit extremely ease to store and transport. The allethrin repellent, is a synthetic copy of a natural repellent found in chrysanthemum plants. The heat generated by the butane cartridge is transferred onto a metal grill that sits over the repellent mat, heat disperses the repellent from the mat into the air, creating the zone of protection. To use the MR300 simply follow the seven steps below:

  1. Insert the mat on top of the metal grill
  2. Remove the bottom cover
  3. Screw in the butane cartridge
  4. Clip in the bottom cover
  5. Turn the switch to the ON position
  6. Wait 5 seconds
  7. Press START Button

About Thermacell

Leisure Outlet welcomes Thermacell, a new brand of us and for the UK! Originally an American brand Thermacell has been proven popular and now spreading their knowledge and product range through Europe.

So what do Thermacell do? Thermacell has one objective, they offer us campers, hikers and homeowners portable and easy to use solutions that provide us with mosquito and midge free zones. Though a range of products from Portable Mosquito Repellers (such as the MR300) to Camping Lanterns with built-in mosquito repellent functionality (such as the Scout or the Bristol Lanterns) we can all enjoy the great outdoors with that extra comfort – whether dining at the campsite or dining on the patio at home.

Each product is designed to provide a 15 x 15-foot zone of protection against mosquitos and midges - protect you and everyone around in a 20m2 area. No need to use smelly, harmful sprays or oily lotions! Thermacell technology uses heat uses heat to disperse a repellent into the air creating a zone of protection from those unwelcomed mosquitoes, midges and other small flying insects. Other than the Thermacell Backpacker, each Mosquito Repeller you would simply insert the repellent mat, insert a butane cartridge and turn on the device. The Backpacker Mosquito Repeller still uses the repellent mats but, runs off standard camping gas canisters (isobutane / propane fuel mix).

Silent in use, no exposed flame and odourless are three benefits of using a Thermacell Mosquito Repeller, with no exposed flames makes Thermacell Repellers that much safer for family camping.


Scientific testing has been done on the Thermacell Mosquito Repellent unit for effectiveness against mosquitoes and other biting insects. The following entities carried out field tests on four continents in areas of high infestation:

  • The Department of Defense, Armed Forces Pest Management Board in Costa Rica
  • The Department of Defense, Walter Reed Army Institute of Research in Korea
  • Hacettepe University – SE Anatolia of Turkey
  • Scientific Coordination, Inc., in Maine, USA

Findings for Mosquitos, Sand Flies and No-See-Ums

  • Protection extends up to 25 feet away from the unit
  • Protection is greatest 7.5 feet away from the unit (15 feet in diameter) and the unit is 95 to 98% effective at this distance.
  • Findings for Black Files:

    • Protection is greatest 3.75 feet away from the unit, where 79% protection was provided
    • The test conducted by Scientific Coordination in Maine was done under windy conditions
    • The report states that in no-wind conditions, the protection level would most likely have been higher
