How to Get Rid of Silverfish Insects

May 18, 2026

Silverfish are easy to overlook because they hide in quiet, dark, damp areas. But for a prevention minded homeowner, spotting one is a warning sign worth taking seriously. These small, fast-moving insects can quietly damage stored items like old family photos, books, important documents, clothing, and keepsakes.

Silverfish are not harmful until they destroy your documents. They do not bite, sting, or spread disease like some pests, but they feed on materials many Wisconsin homeowners store away for years.

What Is Silverfish Insects?

Silverfish are small, wingless insects. They have flat, silver-gray bodies and long antennae and they move quickly and wiggle. They prefer damp, dark spaces such as basements, bathrooms, laundry rooms, closets, wall voids, and attics.

They feed on starches, sugars, and proteins found in paper, glue, wallpaper paste, cardboard, fabric, book bindings, cereal, and stored clothing. That is why they are often found near storage boxes, bookshelves, filing areas, and old keepsake bins.

Why This Information Matters

Silverfish are a property protection issue. A single sighting may not seem urgent, but the damage often happens slowly and out of sight. By the time you notice chewed paper edges, yellow stains, tiny holes in clothing, or damaged book bindings, the insects may have been active for a while.

Wisconsin homes can create ideal conditions when humid summer air, damp basements, poor ventilation, or small roofline and soffit gaps allow moisture to build. Attics and storage areas are especially vulnerable because they are checked less often.

The sooner you act, the better chance you have of protecting sentimental and valuable belongings.

DIY Tips for Homeowners

Start by reducing moisture. Run a dehumidifier in damp areas, use bathroom fans, improve airflow, and repair leaks around pipes, windows, roofing, and exterior entry points.

Then, safeguard your stored items. Remove photos, papers, books and clothing from cardboard boxes and place them in plastic bins that are sealed shut. Also, keep items off the floor of the basement and away from walls where moisture tends to collect.

Vacuum baseboards, closets, storage shelves, attic access areas, and laundry spaces. This helps remove crumbs, eggs, shed skins, and hidden insects.

Seal small gaps around trim, plumbing lines, utility openings, attic entry points, roofline gaps, and soffit areas. Silverfish do not need much space to get inside or move between rooms.
