Silverfish<\/a>, with their silvery sheen and nocturnal movements, often go unnoticed by property owners until they discover unexplained holes in photographs, books, or items of clothing. These unassuming creatures can cause damage to property as they munch through starchy items or those containing cellulose like wallpaper, plaster, paintings, books, and damp clothing.  They love dark, damp, and humid areas, so bathrooms, cellars, cloakrooms, basements, and utility rooms are the areas in a home they are commonly found in.<\/p>\n\n\n\n

What do silverfish look like?<\/strong><\/p>\n\n\n\n

Measuring just 10-12 millimetres in length, the silverfish resembles a tiny silver torpedo in its shape. Close-up the wingless silverfish<\/a> can be seen to have very tiny scales and two antennae, but it is their shape that makes them resemble a fish which gave them their name. Silverfish venture indoors seeking warmth, moisture, and shelter with their activity peaking as homes transition into the cooler seasons.<\/p>\n\n\n\n

What do silverfish eat?<\/strong><\/p>\n\n\n\n

While silverfish themselves are not dangerous, they can become a major inconvenience because of their appetite for starch and cellulose, and a common sign of the presence of silverfish to watch out for is finding unexplained holes in books or items of clothing.  Books<\/strong>, paintings<\/strong>, and photographs<\/strong> are all edible to the silverfish.<\/p>\n\n\n\n
