Silverfish are nocturnal insects with a fish-like appearance. Silverfish are completely wingless and have a long antennae. When walking, silverfish move in a wiggling motion that resembles the movement of a fish. That, coupled with their silver color, earned them their common name.
They may be scary-looking, but silverfish don’t bite humans. They also have not been known to carry diseases. Silverfish are really just a nuisance pest, as they can feed on starch and are often found in books, papers, and carpet.
