Don't let dumpster garbage overflow. Chain the lid down. Bears can easily open most dumpsters. Fruit trees are a common problem during the fall in Montana. Bar the windows.
Bears can easily push through a glass window.
Deodorize with ammonia. Further discourage bears from approaching dumpsters or storage sheds by using loud noise making devices. Fruit Trees and Gardens Fruits and vegetables are not only tasty for humans but among the many natural foods that bears search out in the wild. Even though fruits and vegetables are better for a bear than garbage, these areas are usually close to homes and will quickly habituate a bear to humans. Store grills basement or other secure location when not in use.
