Hello, Jessie.
I'm no master but I do consider myself a journeyman. I've always stuck with the good ol' fashion freezing method. I'm not sure that I trust the chemicals that go into a fumigation event.
I take the article, wrap it in heavy-duty trash bag(s) and make certain that everything is airtight. The colder you can get it, the faster it will be effective. In grad school our guidelines were if the freezer was into the low 20s (f) things might need to be stored for months, -20s, and that time was shortened to a few weeks. We were also taught to freeze for the needed amount of time, let thaw for a couple days, and then shove that sucker right back into the freezer. It tricks the bugs into thinking things were warming up and wasting metabolic fuel.
The Canadian Conservation Institute has a nice write-up as does the NPS's Conserve O Gram found here- https://www.nps.gov/museum/publications/conserveogram/03-06.pdf

Jessie,
If you could wrap the pieces in plastic, so that moisture can't get to the cloth, would freezing be feasible then?

Hello Wise Ones!
My museum has received a large fashion collection that we would like to have treated for pests. Our initial plan was to freeze the objects but a veteran Registrar and Collections guru I know has advised against the difficult, time-consuming freezing process and has recommended fumigation. I have been reading about various, safe fumigation methods on museumpests.net but I'm having difficulty finding a company that is well-versed or even able to accommodate us with this process. Does anyone have some tips, know of reputable museum-worthy fumigators, or even other institutions/contacts who have been through this process that could make a recommendation? We are located in the southeastern region of the U.S. and would love to find someone as close by as possible.
Thanks for your time and energy!
Jessie
