I have a pear tree which I believe is a bradford pear. It was here when we moved in over ten years ago so I am not sure how old it is. I read a comment that someone wrote and I have the same problem. I have millions of small round holes all in the bas trunk of the tree. I just found an huge insect coming out of it molted stage on the tree. I have pics and even a video can I send it to you. I really need help. I also found a huge black bug which I believe is a jap beetle. Thanks
