Thermacell in­tro­duced the first bu­tane-pow­ered per­sonal bug re­peller about 10 years ago. A bu­tane car­tridge ig­nites a small, pro­tected heat­ing el­e­ment that in turn heats a wafer with the se­cret sauce touted to es­tab­lish a dome of pro­tec­tion about 10 feet around it. As the wafer is heated, it emits gases that re­pel bugs. As the wafer de­pletes, it turns from an indigo blue to a whitish-gray color. Once it’s fully white, re­place the wafer. There is also a sight glass to peek in to make sure the bu­tane el­e­ment is burn­ing.

TIPS: Be sure to turn it off when not in use or risk fully con­sum­ing the pre­cious bu­tane car­tridges, leav­ing you un­pro­tected.

RE­SULTS: This and the Back­packer were our go-to gad­gets for keep­ing bugs at bay. It takes about 15 min­utes for the re­pel­lent to cre­ate a pro­tec­tive dome of nearly bug-free bliss.
