Hello. I was hoping to get feedback from those of you who have experienced
freezing textile collections to kill pests.
A few months ago we discovered live carpet beetles (and plenty of dead ones)
in our costume/clothing collection (95% dresses, mostly from late 19th c.,
mostly silk or cotton) . Our pest control people need us to clean
everything out of our three infested, small textile/costume storage rooms so
that they can do a "crack and crevice" treatment. In the meantime, we plan
on freezing our costume collection to kill the pests. This is our plan:
--place each item in a thick poly bag, making sure to pad the shoulders and
folds with acid free tissue. Try to get out all of the air without
squishing the textile. Seal bag.
--place a few bags in a box; seal, label, and inventory the box.
--place box in freezer for two weeks to kill the pests (the local grocery
store is donating space in their huge freezer which maintains a constant
temp way below freezing). We will have about 25 boxes of textiles to
freeze.
--remove box after two weeks and keep in cool room until we place the
textiles back in the pest-free storage rooms.
These are my basic questions:
--should I freeze the textiles for two weeks? what is the minimum amount of
time to freeze pests so they die?
--should I take special precaution with freezing costumes made of certain
materials?
--is there a rust danger when freezing and thawing costumes that contain
metal elements (like buttons, clasps, etc.)?
--anything else I should know or be aware of before implementing my plan?
Sincerely,
