Why silverfish appear
Silverfish need moisture and hide in dark, undisturbed spots — bathrooms, cupboards, roof spaces and bookshelves. They feed on paper, starches and some fabrics, which is why books and stored clothing can be damaged.
How treatment works
Treatment targets harbourage areas and cracks, combined with advice on reducing the moisture that silverfish rely on. Improving ventilation and storage is part of a lasting fix.
Practical prevention tips
- Reduce humidity with ventilation or a dehumidifier
- Store books and papers in dry, sealed containers
- Keep cupboards clean and dry
- Seal cracks and gaps in damp areas
