In our backyard we have a pine tree that we transplanted about 8 years ago. Just recently we discovered that the tree is infested with these weird black bugs. If you walk past the tree you can sometimes hear them making a clicking sound. There is also constanly bee's on this tree. I'm pretty sure the bee's live right underneath the tree in the ground. My dilemma is, I have no idea what these bugs are. There is probably thousands of them if I had to guess. Will they kill my other tree's? Here are some pictures: Thank you!
