Powder post beetles in beam?
Hi, not sure if this is the correct forum, but thought I'd try for your expertise with wood. I found some little piles of fine sawdust in an exposed Douglas fir beam used to build my home in 1983. The beam has some kind of finish on it, but I have no idea what..oil maybe?
I searched and read about powder post beetles and everything says the wood should be removed/replaced, or the house fumigated - UGH!!! Treatments I see say they can't be used on finished wood. Heat treatment? Could I wrap the beam in something (heat tape, or ?) to create enough heat to kill them? It's a 3.5 x 9" solid beam and my whole house is post and beam construction, so I am really worried about them.
Any suggestions? Thank you!
