A full-grown silverfish is about 1/4 a 1/2 inch long. They lack wings and have carrot -shaped bodies, thick at the front and tapering towards the posterior. The young look identical to the adults, but are smaller. Silverfish have two long antennae on their heads and three tail-like appendages on the tip of their abdomens. The five appendages are approximately as long as the body. Silverfish have uniformly colored silver bodies. The silverfish can move very fast which to the untrained eye, can lead to them being mistaken for a cockroach.
Silverfish can be accidentally brought into buildings with boxes of materials that have been stored in infested area. They can also move indoors from the outside. Once inside structures, they move quickly through buildings and search for food. When they find a source, they will generally stay close to it. The silverfish lay eggs in cracks, crevices and other confined spaces. Silverfish prefer cool, moist, dark places with temperatures between 70° to 80° and a relative humidity between 75% to 95%. They can be found nesting in the following areas; basements, closets, bookcases, storage areas, damp areas, boiler and furnace rooms, steam tunnels, insulation around hot water or heating pipes and bakeries.
Silverfish are primarily nuisance insects usually causing little damage. Although very uncommon, potential exists for large, uncontrolled infestations of silverfish to damage paper, book bindings, wallpaper, cereals, starch fabrics, leather, silk and rayon. Silverfish are not associated with the spread of any disease.
