I am going to hunt 2 cyprus swamps early bow season here in Mississippi. Last year I got hammered by mosquitoes, literally ran me out of the woods. This year I purchased a Underbrush Bug suit and a Thermacell. I am going to mount the thermacell on my stand and crank it up when I get situated in the stand. I have read they can take time to work. For those of you that have used a Thermacell in the past what are the pros and cons.
