Hi Tim

Yes, we use anoxic treatment with nitrogen. The only consideration is you
have to leave the item in the 'bag' for a period of time, for us, the
process would take on average about 30 days or more.

Just letting you know the time frame so that you be prepared, in case you
need to access the object for some reason during the treatment period, you
might not be able to.

Hi Tim,

Have you considered anoxic treatment?  Several companies sell anoxic
treatment kits online.  You might also check with some of your
neighboring museums.  If they have an anoxic chamber, they may treat
the items for you.  Our museum uses a carbon dioxide chamber to treat
infested material and we do treat items for other museums for a small
fee.
