Silverfish can be destructive. They feed on most types of human food but seem to prefer starchy materials. Damage can occur when silverfish feed on items such as paper, photographs, books, wallpaper, cottons and linens.
They can be found in all areas of a dwelling and usually prefer dark undisturbed areas such as roof voids and storage cupboards. They are also often found in wet areas such as the bathroom, kitchen and laundry. When managing silverfish infestations particular attention needs to be paid to voids such as the roof and subfloor, skirting boards, cracks and crevices around storage areas as well as wall cavities where possible.
