Silverfish in London Homes: Causes, Risks & Treatment

Silverfish in London Properties

Silverfish (Lepisma saccharina) are small, wingless insects with a distinctive silver, fish-like appearance. They are nocturnal and extremely fast-moving, making them difficult to catch.

Where Silverfish Are Found

Silverfish thrive in humid, warm environments. In London homes, they are most commonly found in:

• Bathrooms and en-suites
• Kitchens (particularly under sinks)
• Airing cupboards
• Basements and cellars
• Around leaking pipes

What Silverfish Eat

Silverfish feed on carbohydrates and proteins, including:

• Paper and cardboard (books, wallpaper, magazines)
• Glue and adhesives
• Natural fabrics (cotton, linen, silk)
• Food debris (flour, cereals, sugar)
• Mould and fungi

Signs of a Silverfish Infestation

• Seeing silverfish at night when turning on lights
• Yellow staining on paper and fabric
• Small, irregular holes in paper and wallpaper
• Pepper-like droppings near feeding areas

Treatment and Prevention

Professional treatment involves residual insecticide applied to harbourage areas. Reducing humidity is equally important:

• Fix leaking pipes and improve ventilation
• Use a dehumidifier in damp areas
• Seal gaps around pipes and cables
• Store books and papers in sealed containers
