What Are Silverfish?
Silverfish are small, silvery, teardrop-shaped insects that move with a fish-like wriggle. They are nocturnal and hide in humid, dark places such as bathrooms, closets, basements, attics, and storage boxes.
They feed on starches and sugars found in paper, book bindings, wallpaper glue, cardboard, and some fabrics, so damaged papers or yellow stains are common signs.
How to Control Silverfish
Silverfish depend on humidity, so drying out their environment is the most effective step, paired with reducing food and harborage.
- Lower humidity with ventilation and dehumidifiers in damp areas.
- Store papers, books, and dry goods in sealed containers.
- Fix leaks and reduce moisture in bathrooms, attics, and crawl spaces.
- Seal cracks and use targeted treatment in harborage areas if needed.
