How to get rid of Silverfish

Silverfish are nuisance pests as they are known for their destructive feeding habits. This includes behaviour such as damaging old books, wallpaper, plaster and other household items.

They survive in most environments but thrive more in high humidity, dark and damp areas such as kitchens, pantries, and bathrooms.

Silverfish are identifiable by their unique silvery-blue colour and carrot shaped body. Their movement mimics that of a fish and are also known to be called fish monks / carpet sharks.

Why do I have silverfish?

Silverfish are attracted to damp, high humidity areas and your home is a good place for them. This is why you will often find them in areas such as kitchens and bathrooms.

How to get rid of silverfish

Silverfish are often found in damp areas of your home and can sometimes be difficult to treat directly.

In these circumstances we recommend puffing a powder such as Residex P Insecticide Powder or Oa2ki Killing Powder.

The powder can be sprinkled into cupboards and cracks and crevices or it can be more accurately applied using a Pest Pistol Powder Duster.

However, if you can easily apply an insecticide directly onto the Silverfish we’d recommend a spray such as Dethlac Insecticidal Lacquer.
