I had to remove two evergreen trees from my property this week that were completely dead. I could hear loud wood chewing sounds coming from the trunks, so I peeled back some of the bark and saw what I believe to be some kind of bark beetle or borer. I can hear similar chewing sounds, less active, coming from a mostly live tree near where the others died.
Is there anything to be done to save trees from these bugs? Or once they are in the bole is there no choice but to count them as good as dead, cut them down, and burn as quick as possible like the others?
