I know a lot of guys swear by scent killers. I think a lot of has to do with where you hunt. I hunt in very thick woods covered with leafs. Most of the guys I hunt with don't do much scent control, other than scraping away the leafs around your stand/blind with your boots. You can clearly smell a earthy/musty smell and when you work it around with your boots I guess it masks your boots a little. The leafs are several inchs thick, even scrape away the leafs when I take a leak and then cover it back up after I'm done. Deer don't seem to wind me even up very close. I had a little 4 pointer walk up to me on the first day of bow season last year. I thought I was going to have to ssush him away to get him off me.
