Interesting. Got pictures? I normally leave any wood with no bark and wet, saggy, rotted, and in your case, « infested » with beetles, for biodiversity and the ecosystem. Or if possible, salvage what I can for outdoor fires.So I have some standing dead Maple that are in the bottom of the slough/gully. Tall few branches nice to work with.
But... They seem to be infested with powder beetles. I cut some last year and it was 1st in last out. Was like handling flour bags and my fear was infesting the wood shed.
Is there a way to kill them? My guess is best leave em to the wood peckers...
