Silverfish are nocturnal and they move and reproduce quickly. They prefer damp, dark areas such as basements, attics, kitchens, and bathroom cabinets. They seek out areas around paper and linen food sources. You can typically find them in stored boxes in garages and sheds. They feed on carbohydrates, particularly sugars and starches, such as shampoos, glue in books, linen, silk and dead insects, making them a destructive pest, as they often ruin papers, clothing and wallpaper. Their natural predators are centipedes, earwigs and spiders.
