Thermacell Refill set mosquito repellent

All Thermacell devices use the same refills. A gas cartridge lasts up to 12 hours, while an active ingredient tablet lasts up to 4 hours. Refills can be stored for long periods. The gas cartridge and active ingredient tablet do not need to be used at the same time. For example, you can use them for just one hour a day. Simply turn it off and use it again at another time. If there is a longer interval of more than 2 days in between, store the active ingredient tablet in a dry and cool place, preferably in an airtight package.
