Silverfish are nocturnal, elongated and flattened insects typically 13–25 millimetres long. Their abdomen tapers at the end, giving them a fish-like appearance.
Lepisma saccharina is the name given to these pests because of their diet. The feast upon sugars and starches and commonly ruin paper and linen materials.
They live in areas that are high in humidity such as wardrobes, basements, bathrooms and garages.
Silverfish will often be found crawling out from behind tiles next to your tapware because of the humidity created by the pipes.
