The silverfish (or fishmoth) is a small, wingless, nocturnal insect. Silverfish are considered a household pest, due to their consumption and destruction of property. Although they are responsible for the contamination of food and other types of damage, they do not transmit disease.

• The silverfish’s common name derives from the animal's silvery light grey and blue color, combined with the fish-like appearance of its movements.
• Their abdomens taper at the end, giving them a fish-like appearance, and they also have two small compound eyes.
• Newly hatched silverfish are whitish but develop a greyish hue and metallic shine as they get older.
