Sam Noble: I was basing -20F on the Museum Pests Recommendation: https://museumpests.net/solutions-low-temperature-treatment/#:~:text=While%20infested%20items%20can%20be,temperature%20treatment%20in%20your%20freezer .
"A freezer capable of reaching minus 20 degrees F (minus 29 degrees C) will sufficiently lower the materials to the freezing point within four hours, which kills adult insects as well as their eggs. If the temperature drop takes much longer, some insects are capable of producing an ‘anti-freeze’ that allows them to survive freezing." Thanks Sandra! I've spent way more time on this, than I care to admit, before thinking to ask this group!

In 1817, the Ojibwe, Odawa, and Bodewadami Nations made the largest single gift to the early University, when they ceded land through the Treaty at the Foot of the Rapids so that their children could be educated. Through these words of acknowledgment, their contemporary and ancestral ties to the land and their contributions to the University are renewed and reaffirmed. -- You received this message because you are subscribed to the Google Groups "MuseumPests" group.
