The Scent Away spray in Fresh Earth has given me very good results. I've used that successfully many times.

Scent Killer unscented, on the other hand is horrible in my opinion. The three or four times I've used that I couldn't believe the number of deer that busted me from 60+ yards away. At first I thought it was just a coincidence, but there's no doubt in my mind that getting winded by that many deer is a result of that spray. I'm much better off wearing nothing on my clothing than I am wearing Scent Killer. [:@]
