(Lepisma saccharina )

A cigar-shaped, silver-grey wingless insect about 12mm long. It is commonly found in damp areas such as kitchens and bathroom.

Can cause damage to paper but feed on residues of starchy substances uch as glues, wallpapers, paste and carbohydrate food debris.

Mature adults lay their eggs in cracks and crevices. The nymphs grow by an indefinite number of moults. Adults known to live for over three years.

Silverfish are commonly associated to a damp issue.


Silverfish are nocturnal, so problems may go unnoticed for long periods. Prevention is usually better than treating with insecticides, as this will only ever provide a short-term solution to the underlying damp problem. Look carefully at the location where the problem is occurring to identify where conditions of high humidity might build up. An open window or a de-humidifier may then be able to solve the problem more permanently.

Treatment, if required, would firstly require the removal of any infested items, such as food packets, books or wallpaper. A residual insecticide can then be applied to cracks, crevices, floorboards and skirting boards.

We recommend treated rooms are vacated for at least 3 hours following the treatment.

Please note that water, such as rain, can wash away our insecticide and thus make the treatment ineffective.
