Hello all,
I have a powder post beetle problem I just discovered.  25 years ago, I stripped an old western North Carolina barn of Chestnut planks, 2x’s, and beams.  The wood was used in a variety of projects including paneling a basement in Atlanta.  Many years ago I moved to California and moved several 100 board feet of the remaining lumber/beams with me.  Recently I dug through the lumber to find a 2×4 to slice up into thin strips for a kayak project and discovered powder post beetle dust all over and around the chestnut barn wood.  Since it is in my garage loft and since the garage is attached to the house, I want to get rid of the pests before significant damage is spread.  So, my questions are about how to get rid of the pests.  I doubt that tenting the house will work as the wood is dry and stacked without stickers.  Many years ago I also bought some European antiques, some of which had powder post beetles and to get rid of the PPB in the antiques they had to be moved into a chamber and poisoned.  Thus, even if the Chestnut was stickered, I doubt that normal tenting would kill them all.  There is also other wood sliced and stickered in other parts of the garage which, to date do not have evidence of the PPBs.  I believe a normal tenting service may have experience with termites, but likely not powder post beetles.  Has anyone solved this problem?  And if so, what did you do?
