Thermacell MR300 Mosquito & Midge Protector

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
