[Nhcoll-l] [EXTERN] Clean Boxes in Pest Infested Room

[Simon Moore]

I agree that Anoxia would work very well if freezer space is an issue.  Try ZerO2 anoxia on google also if you cannot find someone who has a nitrogen tank.  That should find you a nearby source.

With all good wishes, Simon

This can take several month without noticing, and suddenly you get the unexpected pest again. Freezing (two times, with at least a week in between freezing's) is the only certain way to go. There is always the anoxia treatment with nitrogen as a very efficient alternative.

However, I have a number of bins with animal pelts/ taxidermy and while assessing damage of these bins I have found no frass or evidence of pest damage is some of them. I am severely limited on my freezer space, so I was wondering how inadvisable/ risky it would be to not do a freeze treatment for them if they were inspected thoroughly and found no evidence of pests?
