Hello Katie,
I'm not an expert in the process, but the Thermo lignum method (which
combines controlled heat and humidity) has been used on many
composite pieces as far as I am aware.
I don't know if it is available in Canada though.

Hi everyone,
Thanks for all your feedback! My impression is that it wouldn’t be
very practical to use sound right now as an indicator for
infestation. I wasn’t here when the last phosphine treatment was
done, in 2008, but perhaps if I still end up having problems with
Powderpost Beetle I’ll look at different treatment options. I’m not
sure freezing would be the best for this collection though, as many
are fragile wood and composite pieces.
Thanks again,
Katie
