Protect Your Documents and Clothes: How to Get Rid of Silverfish

Silverfish, scientifically known as Lepisma saccharina, are among the most common household pests. The small, wingless insects do not directly transmit pathogens to people, but they can damage books, printed documents, cardboard boxes and clothing made from natural fibers.

They seek dark, humid microclimates, including bathrooms, kitchens, basements and closets. Their diet centers on complex carbohydrates such as starch, cellulose and sugar. Their presence may also signal excessive moisture or accumulated dirt inside a home.

Several control methods are recommended in urban pest-management guidance. Diatomaceous earth can be spread in cracks, along baseboards and in corners. The powder works mechanically by absorbing lipids from the insects’ outer layer, causing dehydration without volatile toxins. Boric acid can act as a poison when insects ingest it, but it should be handled with gloves and kept away from children and pets.

Lavender, citrus, cinnamon and bay-leaf oils may repel silverfish through their aromatic compounds. White-vinegar water can also be applied in problem corners. Commercial adhesive traps placed along areas where the insects travel can help interrupt their reproductive cycle.

The main preventive measure is to change the environment that supports them. Dehumidifiers and prompt plumbing repairs reduce moisture, while sealing cracks removes potential hiding places.
