Well i check my trail camera without using cover scent and deer are back in front of the camera in a couple hours, so it might bug the mature bucks a little bit but as long as you don't go and fill it up every other day and give your scent time to get out of the area then you should be ok. I know some people are crazy about using scent control and i understand that during deer season but every time you step out into the woods is a little crazy. That's my opinion anyway
