Hi Tamar, So there is a good chance they aren’t feeding directly on the feathers and skin. They are more likely feeding on the molds and fungi that has grown on the surfaces of them due to the humid environment. That’s not to say they aren’t limited to mold and fungi as a food source however.

Thanks Joseph, I had no idea booklice would feed on feathers or skin (fooled by the name!). I will try to be more vigilant for them. Unfortunately we are in a humid environment, with no humidity controls in our collection room. Interesting that the info sheet from MuseumPests says this species is not killed by freezing below -18C. Does anyone know if there is a low temperature below which they succumb, or should I heat treat?

Booklice tend to like warm, humid places to live, maybe this is something you can have a look at? I’d also recommend checking other parts of your collection, where there’s a few booklice, there are usually more nearby. In the meantime I’d keep this object separate from unaffected collections.

List, Recently I pulled a raven out of a cabinet and saw it was covered with dust, then I saw the dust was moving! It turned out to be a mixture of what I assume are feather lice and what I assume are eggs (they have crystalline texture, but smooth shape). I would love identification confirmation. Photos attached. Length is about 0.9mm. I am very concerned because I never would have noticed the "dust" if it wasn't on a black background. I would very much appreciate any advice on how to monitor for these nearly invisible beasts and any control or prevention measures beyond the usual monitor/isolate/freeze/clean. thanks, Tamar ****************************************************** Tamar Danufsky Museum Curator and Marine Wildlife Care Center Coordinator Wildlife Department Humboldt State University Arcata, CA 95521 phone (707)826-4034 fax (707)826-4060 www.humboldt.edu/wildmuseum<http://www.humboldt.edu/wildmuseum> www.humboldt.edu/mwcc<http://www.humboldt.edu/mwcc> -- You received this message because you are subscribed to the Google Groups "Museumpests" group.
