Silverfish dart across a bathtub or a box of old papers, then disappear. University of Missouri Extension says they like dark, damp spots. Here is what Overland Park and Kansas City homeowners should know.

Quick Answers

  • They like damp, dark places such as basements, closets, attics, and bathrooms.

  • They eat starchy things like paper, book glue, wallpaper paste, and cereal products.

  • They can ride in on cardboard boxes and used furniture.

Why do silverfish show up in Overland Park and Kansas City homes?

A finished basement, a bathroom fan that never runs, or a stack of old cardboard can give silverfish what they want. The extension says they enter through gaps around windows and doors and arrive on infested boxes and furniture. Adults can live for years, so early action matters.

What should you do first?

  1. Check your bathroom fans and basement humidity first.

  2. Swap cardboard storage for sealed plastic containers.

  3. Look over secondhand books, furniture, and boxes before they go inside.

  4. Caulk gaps around windows and doors.

  5. Cool and ventilate the spaces around hot water pipes and water heaters.

What does not help?

Fix the dampness first. Store-bought products only reach what you can see. The extension says to follow the label exactly if you use one.

Common Questions

Do silverfish damage my belongings?

They can. The extension says they eat paper, book glue, wallpaper paste, and some fabrics such as silk.

How long do silverfish live?

The extension says adults can survive for years and keep molting throughout their lives.

Do you use contracts for silverfish control?

No. We do not use contracts.
