These are about 1/2 inch bluish-silver wingless insects with hard exoskeleton. They look like fish and their movements are very similar. They have 2 long antennas on their head and 3 prominent “tails” on rear.
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
