There are a couple of thingsyou coulddo to prevent that. 1) never let the person handling the bait touch the camera. The bears can smell the bait and think there is a treat inside the little box. 2) climb up the tree and hang the camera from a limb aiming down at the bait. 3) cut a jalpenio pepper in half just before you leave and rub it the juice on the outside of the camera.
