Landowners in the U.S. are now permitted by the Fish and Wildlife Service to shoot menacing grizzly bears with a paintball gun. This was previously prohibited and considered harassment. Previously allowed measures included banging pots and pans, and shooting marbles at the bears with slingshots to ward them off livestock. The new guidelines do require those to clean up any paintball residue however, because the bears are allegedly attracted to the smell. You are also now permitted to use cracker shells, as long as they explode before reaching the bear. Any of these measures taken to ward off a grizzly bear must be aimed toward the rump and away from their face.
