I am having trouble at my mountain home in Mineral Bluff with a bear. I have about 1/3 of an acre covered with mulch around my cabin. It appears that a bear has developed a taste for grubs that are in the mulch layer. The problem begins when the bear encounters the corrugated plastic gutter tubes buried in the ground under the mulch. They are ripping them in small pieces and pulling them out of the ground when they run into them. This has happened three times. The tubes are tore into small pieces, have bite marks on them and the bottom of the gutters are damaged when they rip the tube up. I am getting tired of replacing them. Is there something I could spread around the yard to deter this activity?
