Hi all, The freezer that we have access to has a lowest capable temperature of minus 9 degrees F. I know that this is higher than the parameters for low temperature freezing on the MuseumPests page that Gretchen kindly linked. For this particular beetle, is there any way to utilize our freezer to eradicate the pests?
Thank you for the advice.
