All, I know is I hunt blackwater swamp in MD. Its the nastiest swamp north of a Lousiana Bayou. Two years ago, I littlerly thought my buddy needed to go the hospital. His whole head was swelled up, and arms. I bet he had 500 bites on him. He didn't see on sika because of all the arm flinging he did fighting off the bugs. I used pure deet and it ate the face of my ironman watch. And I even got ate up. My other buddy did't have one bite and had a thermalcell. From now on, I don't go into that swamp in October without one.

I won't use one in your regular hardwoods hunting, but if its a choice between being miserable and scenting deer. I will take scenting deer anyday. We hunt for fun.
