After moving into our new home we noticed a pine tree in the backyard which had holes around the perimeter of the trunk in circles around the trunk.Thought it might be woodpeckers at first but today I saw lots of bees at the holes. They just seemed to climb in a short way and then come out. Can someone tell me what's going on? Will this kill my evergreen? Do they need to be exterminated? If so, how?
Any help would be appreciated?
