A few years ago, I was called is to solve a booklice (psocoptera) problem in an exhibition of photographs. After touring the building, checking out the mechanical system, discussing staff activities for matting and framing, checking the condition report forms and data associated with the environment in the photographs' "home institution, investigating packing and handling techniques, and checking the hygrothermograph and weather data for the period in which this infestation "bloomed", I could find nothing (except an RH spike) that would indicate why these materials were infested. I then checked housekeeping and sanitation records and discovered that the carpeting in the gallery space had been steam cleaned a couple of days before the infestation was discovered. This was the cause of the RH spike and subsequent psocid activity. Interesting how housekeeping impacts real-life practical issues! I'd be interested in hearing of other folks' experiences along these lines.
