Hi Madeline, We have never applied cryotreatment at Winterthur, however having another tool to your IPM arsenal is not a bad thing IMHO.
I’m very curious to hear from others who might have used this treatment. I would have a lot of questions for the contractor if they approached me haha! A big one that I think about a lot due to crazy architecture is the potential effects any treatment or work in space may have on another. I read their testimonials of having no negative effects on electronics or “sensitive belongings” but I would say conducting some sort of Oddy test-like scenario would be worth it if they can’t provide examples. I can see this being most effective against bedbugs, cockroaches and perhaps silverfish the most, as, again, most of their testimonials attest to. Webbing and case-making cloths moths may be a stretch IMHO. If there is evidence to support their presence, then it makes sense to try a treatment. Carpet beetles as well tend to lay near or on animal matter. I guess I leaning towards: if you’ve tried everything else to resolve a pest issue that it’s worth a try before making an investment in a costly system; for me this would include pheromone trapping and honing in on where the issues lie, sealing building envelope, improving temp and RH, etc. etc. - truly managing the pest issue over treating first, asking questions later. I have heard of purpose-built anoxia rooms, in fact Winterthur had one a very long time ago. I have not heard of dual anoxia/freezing rooms. Freezing/Heating rooms/chamber yes. Again, looking forward to hearing from others. Best, Matt Matthew A.

We are using this time to edit/update our IPM plan and think about the future and two questions came up that I would love to get your collective thoughts on: 1) Something that has been recommended by our IPM contractor is adding localized cryotreatment with CO2 snow (https://www.cryonite.com/) to our pest treatment arsenal (for building structure treatment, not for use on art objects). They are recommending its use to kill sticky eggs and pupal casings (ex. webbing clothes moths and carpet beetles) that are in difficult to vacuum areas like gaps between floors and moldings, in between travertine cladding etc. I hadn't heard of CO2 snow being used in this way before. Has anyone used this type of treatment for this purpose? If so, have you had any successes or problems? 2) Has anyone seen or heard of a purpose-built anoxia treatment room (perhaps even an anoxia/freezer combo) in a museum? If anyone has any experience with this, I would love to hear about it as it is something that we are thinking about while we are planning for future space needs. Thank you in advance!
