The MR450 include a zone of protection indicator that allows users to visually confirm the Repeller is up to temperature and establishing the mosquito zone of protection. Additionally, the indicator light will turn off alerting the user that the Repeller needs attention such as running out of fuel. The new accessory mounting system located on the back of the MR450 allows the seamless attachment of a variety of mounting accessories including belt clips and the new multipurpose clamp. These accessories allow a stable and versatile mounting solution.

The improved design of the MR450 also includes a new rubber armoring, giving it the feel and function of an essential piece of outdoor gear. The armoring provides a confident grip and also deafens the sound when the Repeller is set down or transported.


The ThermaCELL insect repellent appliance with Earth Scent is functional gear for hunters. It is the only butane-operated mosquito repellent and cover-scent system.
