Silverfish (Lespisma saccharina)



Silverfish are small, wingless insects usually measuring 20mm or less in length. They have three tails (or cerci) and their body is covered in tiny silver scales.


Silverfish do not have wings, but are able to run very fast. They are usually seen in moist, humid areas in the home, such as bathrooms, basements, and attics.

They feed off moulds and starchy materials like cereals, flour, sweet foods, paper, curtains and wallpaper items. Silverfish can live up to a year without food, but require an environment of high humidity. They move fast and are by nature nocturnal.


While silverfish are mainly a nuisance pest, because they can contaminate food and damage paper goods such as wall paper

and books.

DIY Silverfish Treatments - Get Rid of Silverfish 

If you have a small silverfish infestation and have already repaired the issues with humidity, you may decide to treat the areas yourself to get rid of the remaining silverfish. You can spray the floor/wall junctions with a residual insecticide such as Protector C to kill silverfish as they move along the structure.

Once applied, Protector C is odourless and leaves a residue that kill silverfish for up to 3 months. Click on the picture for more details on Protector C or to buy online.

For more widespread silverfish infestations in wall cavities, attics or under floor boards, you can take further action using some insecticide dust. Diatomaceous Earth such as Desi-Dust is a natural, non-toxic clay that is ideal to use in such areas. If kept dry it will be effective for many months. Dust is also recommended where liquid sprays cannot be used, e.g. behind ovens & refrigerators, at electrical outlets, attic insulation, etc.
