Silverfish eat paper and glue with great gusto. Damage inflicted by
silverfish ranges from sight abrasion to actually eating through pages
of books and other paper based artefacts. They also eat rayon and
cellophane. Unlike messy powders, these silverfish traps are clean and
won’t leave residue on your hands or locations where they are placed.
By infusing boric acid, paper pack and glue with an attractant that is
irrestible to these damaging insects, the silverfish will crawl inside
the corrugated package to eat, and are quickly killed.
