Finding small, shiny insects crawling across your bathroom floor could be a sign of silverfish. These tiny, wingless insects move quickly and prefer dark, damp environments such as bathrooms, basements, kitchens, and closets. They feed on materials containing starch and carbohydrates, including books, cardboard, wallpaper glue, paper, and certain fabrics. Although silverfish do not bite people or spread known diseases, they can damage household belongings if left undisturbed.
The best way to discourage silverfish is to reduce moisture throughout your home. Repair leaking pipes, improve bathroom ventilation, use a dehumidifier when necessary, and keep damp areas dry. Removing clutter is equally important because piles of cardboard, paper, and clothing provide convenient hiding places. Store belongings in sealed containers, vacuum regularly, and seal cracks and gaps around baseboards and pipes to limit their hiding spots.
Sticky traps can also help monitor silverfish activity and catch insects in areas where they frequently appear, such as bathrooms, cupboards, and along walls. Check the traps regularly to identify where the problem is most active. If silverfish continue appearing despite these preventive measures, consider contacting a professional pest-control service for further assessment. Keeping your home clean, dry, and properly sealed can help protect your belongings and make your living space less attractive to these unwanted visitors.
