Silverfish are small, wingless insects known for their metallic appearance and quick, wriggling movements. They get their name from their silvery scales and fish-like movement.
Silverfish live in dark, damp places like basements, bathrooms, kitchens, and attics. They prefer environments with high humidity and can often be found in old books, paper, and stored clothing.
Silverfish eat a variety of materials, including paper, glue, textiles, and food crumbs. They particularly enjoy starchy substances and proteins, making them common in kitchens and pantries.
Silverfish are nocturnal and very fast. They move quickly in a wriggling motion, similar to a fish. Silverfish are secretive and avoid light, which is why they are often found in hidden, dark areas of the home.
Female silverfish lay eggs in cracks and crevices. The eggs hatch into nymphs, which look like smaller versions of the adults. Silverfish grow slowly, taking several months to a year to reach adulthood.
To control silverfish, reduce humidity in your home with dehumidifiers and proper ventilation. Keep areas clean and free of food crumbs. Seal cracks and crevices to prevent entry. Use traps or insecticides as needed to reduce silverfish populations.
Silverfish are not harmful to humans but can be a nuisance. They can damage books, wallpaper, clothing, and food packaging. Keeping your home dry and clean can help prevent silverfish infestations.
