Colleagues at the RS Peabody Museum here in Andover have been treating their pest problem (dermestid beetles and moths) with a program of low-temperature treatment followed by vacuuming and inspecting them. There are a few artifacts that continue to display evidence of insect activity after being frozen twice (each for a period of 2 weeks with a temperature of approximately -27C). Are there any lasting negative effects that they need to be wary of by freezing these objects a third time? Or will the artifacts – woolen woven blankets- continue to be fine with multiple freezings? Feel free to write Marla Tyler, Collections Manager, directly at [log in to unmask].
