Siverfish may be found Within buildings, silverfish may be found almost anywhere. While frequently found in roof cavities, they may also occur in wall voids, subfloor areas and many places within the dwelling parts of premises. They feed on most types of human food but seem to prefer starchy materials. When paper or photographs are attacked, it is often the outer, shiny layer that is most damaged. As well, book bindings, cottons, linens and wallpaper are often damaged. Any sources of glue, starch or sizing are likely to be attractive.
