I cannot give you the exact species; I can tell you this was in a canyon about
40 miles NW of Santa Fe, NM. It may not have been a true PPB, but what else
could possibly be raining down powdered frass from the split cedar logs in the
ceiling of a heated building indoors?

Interesting experience. Could you say something about the species of the
powderpost beetles, you found on “cedar” as softwood ? Because most of all
experiences withLyctus sp. like L. cavicollis / planicollis, L. brunneus and
more,are only on starchy hardwood. Best Stephan Consultant Expert for

Betreff: Re: [PestList] Teaching Lodge Powderpost beetles absolutely will
attack cedar sapwood. The "outer bark" may have some sapwood attached to it.
If it is just bark and no sapwood, then you'll be OK. If there will be some
sapwood attached to the bark, then I suggest heating the bark to at least 130
degrees F. for a period of 3 or 4 hours to insure there will be nothing living
in the sapwood before you install it. I had a significant infestation in a
split cedar log ceiling of an historic building of the US Park Service in New
Mexico some years ago. We had to tarp the entire building and fumigate it with
Vikane. Tom Parker

Subject: [PestList] Teaching Lodge All: We're in the process of renovating
and redoing our 10,000sf history gallery and one section talks about the
Anishinabek history of our area. We've commissioned Native American artists to
make a teaching lodge, which will be not only an immersive exhibit space but
also a classroom for school groups. I'm so stoked about how this will look, but
I am concerned about pest issues. According to the artists, it will be made
with Maple saplings, cedar framing and cedar bark outer shell, tied together
with rawhide. The plant materials will be gathered from the Upper Peninsula of
Michigan this spring and summer, the frame will be installed over the summer,
and the cedar bark outer layers installed in late summer/early fall. One
thing working for us is that install of this piece will finish up 3-4 months
before the first artifacts go into the space. From what I can tell,
powderpost beetles don't attack cedar or maple, but what other pests do I need
to look out for? Any suggestions for how to mitigate the risks? I look
forward to your input and suggestions. Geoff Woodcox Curator of Collections
