Tim -

You should consider anoxic eradication. It's a simple technique of 
bagging the object in an airtight bag and scavenging all of the oxygen 
out of the enclosure for a sustained period of time.

You can contact CCI there in Canada (The Candadian Conservation 
Institute) or drop me a line and I'll dig up some resources on this for 
you.

Subject: Insect eradication on large artefacts

   Hi all;

We've got some large pieces (taxidermed animal heads, including a
whoppin' big elk) that are/may be infested.  We usually freeze suspect
pieces, but these ones are too large to fit in our chest freezer.  None
of the commercial freezers in town want anything to do with bugs coming
in their facilities, which all store food items.  There are no freezer
trucks available in town (we're waiting on a quote to rent one from 2
1/2 hours down the highway)--I suspect that cost may be prohibitive, and
I understand they may not be cold enough to do what we want them to
anyway.

I've looked into treating these pieces with chemicals, but I'd rather
stay away from stuff with names like chlorpyritos, diazinon or
pyrethrins....

So, rather than kicking myself for not having been on the ball to take
advantage of some days of our cold Canadian winter just passed, does
anyone have suggestions for non-chemical means of eradicating our
unwelcome residents?

Thanks,
