My scent control is washing clothes in home made soap or baking soda and using the wind to my advantage.
My camo is usually a dark brown or dark green shirt and faded blue jeans. In cool weather I will wear a camo sweat shirt on top.
I've killed my share of deer and seldom get "busted" unless the wind shifts or swirls.
I do a good bit of hunting in archery season and most of my shots are well under 20 yards.

The last one I killed was a small racked buck that walked within 5 yards of my 12' ladder stand and I shot him at about 10 yards.
He came in from a quartering angle to the wind and walked downwind of me, but being 12' up kept my scent from reaching him when he was that close.
