This past bow season I went to the thermocell. If your not familiar it is a thermal bug repelant. Many of myfriends suggested andrecommended it to me. However I believe the deer can smell the thermals it produces. As a human I can smell it so whats that say. The company claims it to be scent proof to wildlife. I had 3 occasions w/ my bow that deer walked up on me and began to blow and wheeze and get out of the area. I am areal fan of scent-lock technology so I just find it hard to believe they reacted to my scent. Anyone here use this repelant or have any suggestions? thanks...best of luck to all
