Covering an effective distance of 15 feet the refills create a zone of protection around the user rather than relying on a sprayed-on repellent that wears off with sweat or water exposure. Being unscented the refills avoid introducing competing odors that could alert game to a hunter s presence an important consideration for anyone using them in the field. This makes the R2 refills particularly well suited to hunting applications where scent control matters.

The convenience of a refill-based system means users do not need to reapply repellent to their skin or clothing throughout the day.

Thermacell has built a strong reputation in outdoor pest control and these refills keep that protection going session after session.
