there's no easy way to get out of your stand when hunting over bait. I read in bowhunting magazine where Bill Winke a well known bowhunter would lower his bow to the ground and bounce it in the leaves to try to scare them off but that isnt fullproof either. Another way he's used to scare them off was to take a sling shot with him and some rocks and shoot at the deer or the ground in front of them, which worked really good and they didnt pose it as human threat.
