Good luck with the bears. Bears don't scare easy, since they are usually the meanest critter in the forest (except, a drunken redneck with a gun, or a semi truck). They tend to be more curious, than fearful. If bee stings don't deter them, doubt loud noises will either. I heard many times as kid, that even an electric fence doesn't phase them. If you really want to see scary, let momma bear see you messing with a cub, you feel the earth shake (maybe it's just your legs...). Bears like the honey, because it's sweet, nutritious, and has some anti-bacterial qualities. They'll destroy anything to get at it. These are very strong and persistent animals, maybe not particularly smart, but they make up for it in other ways. About the only thing that works, is to trap and relocate. Don't believe in killing for convenience, least not for animals like this.
