Silverfish are teardrop-shaped and white to brown-grey or bluish-silver in colour, they can measure up to 12-19 mm in length and have three long bristles on the rear of their body.
Silverfish are capable of thriving in most climates, but prefer to dwell in dark, damp areas such as basements, attics, kitchens and bathrooms. Silverfish feed on carbohydrates, particularly sugars and starches, cellulose, shampoos, glue in books, linen, silk and dead insects may be food sources and they have even been found in unopened food packages. They are especially attracted to paper and damp clothing. So are commonly found in stored boxes in garages and shed.
