I bought a thermacell the other day and then a buddy of mine that I alsowork with talk me out of it. He made a good point about the weather in WI getting cold so why would I need one. I should have kept it. I also have the same spray you mentioned and I thought it would smell to much. On windy days I have no problems with bugs. I should have kept the thermacell even if I only used it a couple days. I will be hunting tonight and it is cool out and there is a nice breeze so I am not to worried. But I tell you I was ready to jump out of that stand on Sunday morning. My hands are still all welted up. But I may just bring the sent shield bug spray if you say you have used it with success.
