Thank you Mr. Sorkin, this is valuable information especially for small herbaria that don't have staff trained in IPM management. I'm changing my sticky traps to reflect your suggestion and taking my occasional silverfish more seriously. On Thu, Jan 23, 2020 at 12:25 PM Louis Sorkin <sor...@amnh.org<mailto:sor...@amnh.org>> wrote: It’s interesting that most people associate starchy compounds with silverfish rather than proteins. So searching for potential infested materials should include protein sources such as dried animal matter including dead insects. Dead insects could be from other infested materials and the silverfish are your cleaning crew. Some pest control websites usually pay more attention to non-proteins: Capable of thriving in most climates, silverfish prefer to dwell in dark, damp areas such as basements, attics, kitchens and bathrooms. They are especially attracted to paper and damp clothing. Commonly found in stored boxes in garages and sheds. Silverfish are known for their destructive feeding habits, oftentimes ruining papers, clothing and wallpaper. Silverfish eat carbohydrates<http://ento.psu.edu/extension/factsheets/bristletails-silverfish-and-firebrats> like flour, rolled oats and starches in cardboard boxes, paper, book bindings, glue and insulation. Silverfish feed on carbohydrates, particularly sugars and starches. Cellulose, shampoos, glue in books, linen, silk and dead insects may be food sources. They also eat protein, such as dried beef and dead insects. They have been found in unopened food packages. Don't keep old books and magazines in areas where silverfish are usually found like basements, attics and garages. And it's important to keep food items such as flour and sugar in tight containers.

I have noticed that in some of my storage areas that are prone to silverfish, I have often found silverfish stuck to the underside glue strip (the one that holds the blunder trap to the floor). In some cases I have had many small silverfish on that underside glue strip and none at all on the main glue surface on the upper side. I assume that means they like to stick close to the floor surface and sheltered areas, especially when they are young. I am going to experiment with this method, though I’ll have to invest a whole 25 cents per trap rather than 5 cents as Canada has stopped using pennies! ; ) Dee Dee A.

Silverfish love to squeeze themselves into dark cracks and crevices. The pennies give them a perimeter of crevices around the entire glueboard. It's particularly helpful in situations on shelving where starchy items are stored. It's also great around the perimeter of a basement concrete floor where silverfish like to hide in the expansion joints.

The trap is not directly near paper, but there is a lot of paper-based historic materials in that room. First, is this a silverfish like a think it is? Next, what should I do in terms of notifying my supervisors and what are the best practices for next steps? Should a professional pest management company come in to inspect the space. I only found one silverfish, so does that mean there is an infestation or only a small amount (which is still problematic but not as big a cause for alarm). I look forward to hearing from you all.
