A Glimpse Into Silverfish
Silverfish are wingless, having a fish-like appearance with a flat body, which is tapered at both ends and covered by overlapping scales. They prefer damp, moderate temperature places such as basements, kitchens, sinks, bathtubs, behind baseboards or wallpaper, window or door frames, and wall voids. This insect is about 1/2 inch long, named for the tiny silver scales on its body.
Silverfish require a large supply of starchy foods or molds. They are considered a nuisance pest that can feed on wallpaper pastes, natural textiles, books and papers. They also feed on mold or fungi that can grow on various surfaces. Silverfish are fast-moving and can travel throughout buildings. Silverfish are active at night or in dark places found throughout the structure. You may see silverfish trapped in sinks and bathtubs because they enter seeking moisture and are unable to climb a slick vertical surface to escape.
Silverfish go through a three stage life cycle called gradual metamorphosis. Many insects have a four stage life cycle called complete metamorphosis. Silverfish lay eggs throughout the year, and take 19-43 days to hatch. The life cycle from silverfish egg to adult is three to four months.
