Actually Amos, I hear spraying the Bear Guard around the campsite is not a wise thing to do. Statistically it seems to attracted the bear. The pepper scent makes the bear curious. To use the jetting spray as a defense is another matter.
Best not to leave the treats in the woods to deter the bear from seeking snacks within your campsite. That will only lure the bear and create a garbage bear out of a wild bear.

The chances of being attacked by a garbage bear or being in the wrong place with the wrong bear is about the same as the chances of being struck by lightening.
