If you can’t use anoxia I would see if you can get permission from the artist
to use boracare which is a mild boric acid solution that uses a form of glycol
to transport the boric acid into the cells of the timber. This product is used
on construction and log homes. Mixed 3 parts water to one part boracare. Drys
clear. Dusting cracks may miss powder post beetles. JTV

Hi All!
I have a question about book lice and the treatment boractin that I was hoping
to pose to the group. We have a set of works that were lent to our museum that
it became clear are infested. The works are trees that have been partially
carved. So part of the work is the raw outside of a tree, moss still attached
in some instances. Supposedly they were heat treated in the past, but it is
clear that either didn't work or they have been reinfested at some point. We
have seen the presence of book lice and possibly some moths. I found an
additional casing from a yet un-identified insect this morning. One problem is
that the trees are very large and need to remain on view for this exhibition if
possible.
We have consulted an IPM specialist who recommends treating the trees with
boractin dust. I have not heard of this treatment used on museum objects
before and was hoping to get a little insight from the community. Our IPM
specialist says that the boractin will leave no trace on the trees and only be
inserted into the cracks and crevices using a bulb duster. Does anyone have
any thoughts on this? Should I be concerned about any long term effects of
using it on the trees?
Thanks so much for your help,
Ariana
