I live in the woods. Killing a few animals won’t solve the problem. I harvested the pears today. I found that a bear cub had slipped through the electric fence, somehow made it through the poncirus branches that I guess were scanty on one side of pear tree, climbed it and tore off several branches trying to get to the fruit. Most of the fruit were shaken off the tree onto the ground and most were not chewed on as they were covered by the pile of poncirus branches around the tree. I think the bear fell into the poncirus branches as the long frail limbs of the young pear broke, he couldn’t get under the pile of thorns to get the fallen fruit, and he left. At least I got enough fruit to make some pear preserves. Lot of work though.
