What is everyone doin to keep moths at bay?

This kind of thing - https://www.spacebag.com/ - protects the kilt and stops any "escapees"...

Just remember that water that was in the kilt stays there. If you store that package at considerably lower temperatures you might get a moldy kilt. (There is a reason why we don't have archive documents in such bags.)
To get an idea how little a temperature difference might be considerable check the graphic in this link and remember, that with it being a vaccumed bag, there is nearly now air in it so that any drop of water will be a threat (it might be a mild one but it is a threat).
