I live and hunt in Florida..mosquitos are a real problem during bowseason and sometimes gun season here. The Thermacell is the greatest thing invented since sliced bread. Yes, there is a smell associated with it, but because it is being heated it rises. I guess it cools and eventually comes down, but I have had deer less than 10 yrds away and have never been winded. Good Luck, I don't go in the woods without mine during bowseason.
