I'm cleaning up things and organizing what to keep and what to donate as I
settle my Mom's estate. Tonight I was finally tackling the garage, where she
stored her antiques and craft items until she got around to cleaning, restoring,
etc. I have found quite a few piles of what sure looks like powder post beetle
barf.

The garage is about 20 years old. Stick frame construction, then horizontal
nailers were put on to allow installation of board and batten siding. Siding is
rough sawn poplar as are the battens, and are well painted. The inside is raw
wood. Because of snake intrusion via warped battens, Mom had the inside sealed
with some 1-1/2 x 1/2 poplar strips to help keep out those of a scaley
persuasion. Spot checking shows that most of the beetle holes are in these
interior strips.

I will do some more research tonight, but I figured if anyone out there had a
solution it would be on this group. I had planned to fog the garage this
weekend, although that probably will not be much help with the PPB problem. Any
suggestions? The garage is actually mostly empty (at least compared to my
garashop). I will do some heavy inspecting in the daylight of the building and
contents. Just hoping for some (relatively) easy solutions to this problem, but
think it will actually involve many applications of a nasty insecticide.

Thanks for any input.

Roy

I have used Timbor and it works, though you may have to retreat
