I was wondering whether the deer would be able to smell bug repellent if you are wearing some while out hunting. Is there a specific type of bug repellent that can be used that is less likely to make deer shy away from the area?
Yes, deer will smell your bug spray. Even if you use all the fancy scent-eliminating sprays, soaps, and clothing detergents they can still smell you if you are sweaty. Most important is the wind factor: Deer will smell you if they are downwind of you.

I would say use the bug spray you would have used anyway. Just make sure you carefully monitor the wind and plan your hunting spot carefully.
