These are agile, fast running, scale-covered insects that are primitively wingless. About 5 species have successfully invaded buildings. These pest species restrict their activities to relatively undisturbed reas (eg. Bookcases, storage rooms), where they may damage paper, fabrics and other materials.
Within buildings, silverfish can be found 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.
Why are they considered a pest?
Silverfish feed on most types of human food but seem to prefer starchy materials. As well as paper they will also feed on book bindings, cotton, linen, and wallpaper. Any source of glue, starch or sizing are likely to be attractive.
