We put it out from the start. That will keep the bucks looking. I put it on my shoes as soon as I'm out of the truck. anything that crosses my path will follow the scent. I only use Ambush scent by Moccasin Joe. I've had a buck chasing a doe cut off and follow my scent to the tree I'm up in and got shot at 10 yards. They're in the rut heavy right now. go get one!
