The success of the Thermacell personal device led the makers to introduce the Backpacker repeller. It uses a similar protected butane-fired element to heat the repellant wafer. It is fueled by a large camp-stove butane tank, giving coverage for days, not hours, which is a primary advantage over the personal device because it provides comparable coverage without changing butane cartridges.
TIPS: You will be covering the campsite with this gadget, so take plenty of replacement wafers. One tank should offer protection for several days.
RESULTS: The Backpacker’s larger fuel source is a great benefit. We had comparably good results with it, enjoyed the ability to burn it longer and weren’t as concerned about shutting it off when we went inside.
