the electric fence isn't strong enough to stop a bear. Its for raccoons and dogs and things like that. Does anyone have any suggestions?
I have seen the suggestion to put some bait on the electric fence wire (smear of peanut butter, or tie a strip of bacon around it, or stick a hotdog on it, or something of the sort.) That would encourage a bear to sniff or bite, so it gets shocked on the nose or mouth (sensitive areas), instead of just pushing through the fence with a furry shoulder that won't feel anything.
(I haven't tried it, but I've seen this type of suggestion frequently.)
