Both methods work well when done correctly. My preference is always for freezing (or heating) because it takes less time to achieve results than anoxia and it is easier to set up. Follow the guidelines for freezing on MuseumPests.net and you should have no problems. When the object is well sealed in a double bag there will be very little fluctuation in the RH in the immediate environment. If you are concerned you can place a sorbent of some kind, (Silica gel etc) in the bag. Try it on scrap cardboard if you are concerned. Freezing has been used successfully to mitigate pest issues on books and other paper products for many years - it is very successful. Good luck!

There is a risk of damage to any binders if present (i.e. glue/paste), so if that is the case I'd use low oxygen.

The piece is a chair by architect Frank Gehry and it has silverfish. Freezing? Anoxia? Is one better than the other for these critters? I would think freezing might be damaging to the cardboard but I'm not sure.
