Why Are Silverfish a Nuisance?

Even though they won’t harm you, silverfish are pests for good reasons. They are active at night and hide in dark, damp places. Their sneaky nature means an infestation can grow without you noticing right away.
Silverfish Damage to Belongings
Silverfish love to eat things that have starch or sugar. This includes many items you have around your house.
- Paper and Books: They will chew on the glue in book bindings, wallpaper, and even eat the paper itself. This can ruin your favorite books, important papers, and family photos.
- Clothing and Fabrics: Silverfish are attracted to natural fibers. They can make tiny holes in clothes made of cotton, linen, and silk, especially if they are stored in damp closets.
- Food Contamination: These bugs can get into your pantry. They might crawl into open boxes of cereal, flour, and oats. If they get into your food, they can leave behind tiny droppings. It is always best to throw away any food that has bugs in it. We published a latest post on Best Silverfish Traps and Prevention Tips. 2025 Guide
Silverfish Health Risks and Other Concerns
While not directly harmful, there are some minor silverfish health risks and other problems to be aware of.
- Allergies: Some people can be allergic to the scales that silverfish shed as they grow. A protein in these scales can mix with dust in the air and may trigger allergy symptoms like a runny nose or itchy eyes, similar to dust mite allergies.
- Sign of Moisture Problems: Finding silverfish is a big clue that you have a damp area in your home. These bugs need high humidity to live. According to pest experts at Orkin, their presence can point to hidden leaks or moisture issues that could lead to bigger problems like mold.

How to Get Rid of Silverfish in Your Home

Finding silverfish doesn’t mean you have a dirty home. They can sneak in through tiny cracks or be brought inside in cardboard boxes. The good news is that you can take steps to get them out and keep them away.
- Reduce Humidity: The most important step is to make your home less friendly for them. Use a dehumidifier in damp areas like basements and bathrooms. Fix any leaky pipes and make sure your rooms have good airflow.
- Seal Cracks: Look for small gaps around windows, doors, and pipes. Use caulk to seal these entry points so silverfish can’t get in.
- Store Items Properly: Keep dry foods like flour and cereal in airtight containers. Store old books and seasonal clothing in sealed plastic bins instead of cardboard boxes.
- Clean Up: Vacuum your floors and carpets regularly to pick up food crumbs and silverfish eggs. Getting rid of clutter, like stacks of old newspapers or magazines, removes their hiding spots and food sources. As noted by health resources like WebMD, keeping your home clean and dry is a top defense against these pests.
