White to brown-grey or bluish-silver in color, silverfish are teardrop-shaped insects that measure up to12-19 mm in length. Three long bristles on rear. Grow from egg to adult without visible change in appearance. Capable of thriving in most climates, silverfish prefer to dwell in dark, damp areas such as basements, attics, kitchens and bathrooms. They are especially attracted to paper and damp clothing. Commonly found in stored boxes in garages and sheds. Silverfish feed on carbohydrates, particularly sugars and starches. Cellulose, shampoos, glue in books, linen, silk and dead insects may be food sources. Have been found in unopened food packages.
