There is a lot of down time during the season. Early on when the weather is still hot, that down time brings a whole host of annoying biting bugs to camp which make getting rest a challenge. We have to admit that we had our doubts with the plastic appearance of the ThermaCELL ($26.99). At our wit’s end we were willing to try anything and this little unit delivered. Biting flies and mosquitos hate it, which guarantees we love it. You can’t put DEET on the dogs and it’s probably not a great idea to cake it on yourself either and with the ThermaCELL you no longer have to. Purchase a ThermaCELL.
