Therma Cell works very well - use what ever wind you have to your advantage and place it up wind. I did attach a string loop to the back to make it easier to hang on trees at times.
OFF! brands also has a similar type device but it is not heat activated as a Therma-cell and that works too.

Turkey Hunting! ~ One Turkey Calling Another!
the therma-cell is a live saver. We hunt by a river a lot and sometime we got pushed out because of the misquitos and then we got these and they work amazingly.
I did a poll on here a few years ago and there was only 1 vote saying they didn't work. I think that person just must not have been using it right.
Here's a link to the thread, the poll part must have been lost in the conversion to the new format last year, but in the very last post it sounds like it was at 98% saying that it works.
