Its funny to me how much money we spend on hunting items. The $25 you'll spend on the thermocell kit will be some of the best $25 you'll ever spend. Sometimes the best and most practical items cost the least.
I go back home (SW FL) to hunt hogs in the winter. If temps are warm, skeeters are out and if they're are hungry....There's no stopping them. I had two thermo cells with me last year in the stand and just about gave up they were so bad. Glad I didn't, shot a good bar. But that's just me, maybe I taste better than everyone else that's commented on them
