This would certainly work if materials are in cases, containers, boxes, isolated rooms, etc. Sealing (as Tom noted) is key to restrict movement from areas of poor condition to better condition; from foci of infestations to other places such as commodities, containers, cases, closets or rooms. These insects do have legs and are able to crawl or stay in more hospitable places and not stay where conditions are less favorable. If a reservoir population exists within the walls, the microclimate conditions are not deleterious to their lives, but those in your storage case collections are. Here is where sealing comes into play. You are managing the populations this way, but not totally exterminating them. I remember a psocid researcher told me that under excessively dry conditions certain booklice will dry up, but when conditions are more hospitable and RH increases, the insect will "wake up" and not really be dead.

Nearly every collections storage area that I have visited in the US has had some presence of psocids. Generally, the museums that say they do not have them are either not monitoring or they are overlooking the tiny specks on the edge of their sticky traps and assume that anything that small must be dust. Even though an institution may have psocids, this does not mean that there is a major concern. Documented damage occurs when the numbers are extremely large (100's to 1,000's) in isolated areas. Capturing a couple on a sticky trap every few weeks means that you should stay alert and continue monitoring, but is not a cause to be overly concerned. As both Tom and Gretchen stated, small increases in temperature or decreases in RH will cause these soft-bodied, moisture loving insects to dry up and die. Here is the link to the psocid fact sheet on museumpests.net: http://www.museumpests.net/pdfholder/27image.pdf It offers good information. Good luck, Pat Kelley Insects Limited, Inc.

I've just discovered psocids in an insect and herbarium cabinet and am interested in finding out if anyone else has had this issue and how it was corrected. Thank you, Amy K.
