Another advantage of being high in a tree! I noticed when I went from my 15' ladder to the 22' one my mosquito problem is about zero. Seen on a discovery channel show once that was talking about homes down south as to why they always had second story porches and it was because of bugs they said people learned a long time ago most insects stay close to the ground. Early season and high in stand I have very few get to me. I have also heard alot of people like Tom that like the ThermaCell, but I have not used it yet.
