How to Treat Silverfish

Silverfish are considered household pests, due to their consumption and destruction of property. However, although they are responsible for the contamination of food and other types of damage, they do not transmit disease.

What do Silverfish look like?

Silverfish are nocturnal insects typically 13–25 mm (0.5–1.0 in) long.[1] Their abdomens taper at the end, giving them a fish-like appearance.[2] The newly hatched are whitish, but develop a greyish hue and metallic shine as they get older.[3] They have two long cerci and one terminal filament at the tip of the abdomen between the cerci. 

A silverfish (Lepisma saccharina) is a small, primitive, wingless insect in the order Zygentoma. Its common name derives from the animal’s silvery light grey colour, combined with the fish-like appearance of its movements. The scientific name (L. saccharina) indicates the silverfish’s diet consists of carbohydrates such as sugar or starches.

Life Cycle of the Silverfish

Silverfish go through a three-stage life cycle called gradual metamorphosis, whereas most insects have a four-stage life cycle (complete metamorphosis). The life cycle from silverfish egg to adult is three to four months.

Silverfish can lay eggs at any time during the year. The female lays groups in small batches, usually deposited in small crevices in dark places. The eggs take 2 – 8 weeks to hatch.

When the nymphs hatch, they are whitish in colour, and look like smaller adults. As they moult, young silverfish develop a greyish appearance and a metallic shine, eventually becoming adults after three months to three years.


Where do the live?

You find Silverfish inside, usually in dark damp undisturbed areas. You rarely see them outside.

What do they eat?

Silverfish love to eat anything made of  carbohydrates such as sugar or starches. These include book bindings, carpet, clothing, coffee, dandruff, glue, hair, some paints, paper, photos, plaster, and sugar. Other substances they may eat include cotton, dead insects, linen, silk, leftover crumbs. So be aware your library of old books might be under attack!

*Silverfish can live for a year or more without eating if water is available.
