Silverfish are usually silver or grey in colour, with a metallic sheen.


Silverfish are small insects, usually measuring between 612 mm in length.


Silverfish are small, wingless insects that have a metallic silver or grey body with fish-like movements. They have three long, slender, tail-like appendages at the rear of their body. Silverfish prefer dark, damp, and warm places such as attics, basements, bathrooms, and kitchens. They can also be found in books and closets where they feed on the glue in the bindings. 

Where do silverfish live?

Silverfish are small, wingless insects that thrive in moist, dark environments. They are nocturnal and can be found in a variety of places in the home, such as bathrooms, kitchens, basements, attics, and garages. Silverfish are also found in dark crevices and cracks in walls, under carpets, and in any other area with high humidity. 

These insects feed on a variety of items including paper, glue, and fabrics, so they can often be found in bookcases, closets, and storage boxes. They also love to feed on mould and fungi, so they can be found near plumbing fixtures and damp areas of the home. 

In order to control silverfish, it is important to reduce the humidity in the home and keep the area as dry as possible. This can be done by using dehumidifiers and fans. Additionally, it is important to keep the home clean and clutter-free to reduce the number of potential hiding spots for silverfish. It is also important to seal any cracks and crevices in walls, floors, and ceilings to prevent silverfish from entering the home.

Finally, it may be necessary to contact a professional pest control company to ensure that all potential silverfish breeding sites are eliminated. They can provide targeted treatments to the areas where silverfish are found and help to prevent further infestations.

How long do silverfish bugs live?

Silverfish typically live for 12 years, but some individuals have been known to live up to 8 years. They reproduce by laying eggs, which can hatch in as little as 2 weeks, allowing the population to grow quickly.

What do silverfish eat?

Silverfish feed on a variety of items including paper, glue, and fabrics, as well as mould and fungi. They also feed on starches, such as cereals, flour, and even wallpaper paste.

Why do I have silverfish?

Silverfish often enter the home in search of food and shelter. They love moist, dark environments and can be found in bathrooms, kitchens, basements, attics, and garages. Silverfish also enter through small cracks and crevices in walls, floors, and ceilings. Unsanitary conditions, clutter, and high humidity can all contribute to an infestation.

Habitat, Diet, Life Cycle


Silverfish are found in moist, dark places such as under rocks and logs, in bathrooms, kitchens, basements, and attics. They also live in and around books, as they feed on the glue used to bind them together.


Silverfish are omnivores, meaning that they feed on both plant and animal matter. Their diet consists of carbohydrates such as sugar, flour, and starch, as well as proteins like dead insects, book bindings, and fabrics. 

Life Cycle:

Silverfish undergo an incomplete metamorphosis, which consists of three stages: egg, nymph, and adult. The eggs are laid in groups of up to 200 and take between 2-8 weeks to hatch. The nymphs then moult several times before reaching adulthood, which can take up to a year. Adult silverfish can live up to 3 years.
