Per the title. A client was on the job with us yesterday, and talking about his tree woes. EAB was one, but he was also talking about oak die off. A tree would dies within one or two years, and there would be fine sawdust around the tree, with little bugs causing it? Not carpenter ants. This guy wasn't particularly knowledgeable, so I didn't question him, but I was curious. Oaks seem to be doing poorly as of late, but I haven't been hearing much around about it. The big problems I read online about are always elsewhere.
