Jack,
I'm not exactly sure about the configuration you speak about of the area where the silverfish are appearing, but they might wish to try a product we at the library, and I, personally, have used for many years that functions extremely well in keeping those creatures away. What I am talking about is called DekkoPak. These are small 'sandwiches' that have borax in the center. We tape them to the uprights of our shelves and change them about every year. You can buy them at Vermont Country Store and many other places, e.g. here we get them at some Home Depot, and Longs Drug Store locations. You might want to read the article I wrote years ago: http://www.archival.com/newsletters/apnewsvol10no1.pdf, it gives a bit more information. I also believe that humidity is more important to keep in check than temperature, but both should be monitored. Humidity of around 45-50% would be best. Since these pests are found worldwide they've become acclimated to just about any condition. Good luck! Margit Margit J.

The area is on the second floor of the building and is maintained at 49-70 degrees. I've asked them to step up their monitoring program but was wondering if or how any pesticidal applications might be beneficial? We're discussing use of aerosolized silica dust but are open to other thoughts. The storage area is quite large and access to the perimeter is limited for the most part by the collection itself. Any thoughts? Jack Wiler Accounts Manager Acme Exterminating Corp. 365 W. 36 St. New York, NY 10018 212-594-9230 Office 347-834-1576 Mobile 212-736-2746 FAX No virus found in this outgoing message.
