Silverfish Exterminators

Serving St. Louis | St Charles | Belleville | Edwardsville | Champaign

If you’ve seen small, shiny gray bugs darting away when you turn on the lights, you’re likely dealing with silverfish. These moisture-loving insects are wingless and feed on household items like paper, clothing, and adhesives. The best way to eliminate them is by reducing humidity, removing potential food sources, and bringing in pest control experts for lasting results.

Here in St. Louis, the rainy seasons create perfect conditions for silverfish infestations. They thrive in damp environments and tend to appear most often in fall and winter. Though harmless to humans and pets, their quick movements and odd appearance make them one of the most disliked pests homeowners encounter.

When it comes to household pests, Bug Out is here to help you identify and stop them fast. Whether you’re trying to figure out what’s lurking in your bathroom and crawl spaces or you’re used to seeing silverfish, read on.

What Exactly Are Silverfish?

Silverfish are small, wingless insects known for their sleek, silvery appearance and darting, fish-like movement. They measure around ¾ of an inch long, have slender bodies, and use their long antennae to navigate dark, damp areas of your home.

In St. Louis, silverfish can live up to three years if conditions stay humid and food sources remain plentiful. They’re known for eating just about anything that contains starch or cellulose, including paper, fabric, wallpaper, and glue.

Once they find their way inside, they’ll continue to search for new sources of nourishment. That can include household items like clothing, carpet fibers, and even their own shed skins. Seeing them in the bathroom, basement, or under sinks often signals a growing silverfish infestation.

How do Silverfish Find Their Way Into Your Home?

Silverfish often sneak into homes through the tiniest cracks, gaps, and openings around doors, windows, or foundations. Once inside, they seek out moist environments like bathrooms, basements, and kitchens where humidity levels are high. These insects thrive in dark, damp spaces, which makes them especially common in St. Louis homes during the rainy season. If your home tends to stay humid, it can easily attract them.

Because silverfish are nocturnal, you’re unlikely to see them crawling around in daylight. They prefer to stay hidden in crevices or under objects until nightfall. When the lights suddenly switch on, you might catch one darting across the floor or along a wall, disappearing as quickly as it appeared.

Are Silverfish Dangerous?

Silverfish don’t bite humans or transmit diseases, but they can still wreak havoc on your possessions. Their small size and quick movements allow them to hide easily in drawers, closets, and storage boxes. Once they find a food source, they’ll feed quietly, leaving behind small holes and stains. Preventing moisture buildup can help keep them from spreading.

These pests love paper-based items and will happily feast on books, photographs, and important documents. Silverfish are also drawn to fabrics made from natural fibers, such as cotton, silk, or linen. If you find mysterious damage to clothing or paper, these sneaky insects might be the cause.

Effective Ways to Eliminate Silverfish

Getting rid of silverfish starts with making your home uncomfortable for them. Using dehumidifiers in areas like basements or bathrooms will help control humidity. Consistent home maintenance can prevent infestations before they start. Some of the factors that might have drawn them in include:

How to Prevent a Silverfish Infestation

To prevent silverfish from getting inside, fill in gaps around your walls, foundation, and siding. Remove sources of stagnant water and clean up excess yard waste in your yard. Since they can feed on a wide variety of materials, these actions are a good place to begin:

  • Food Storage: Keep carb-heavy foods in airtight containers to prevent silverfish from feeding.
  • Insulation Protection: Limit access to insulation by ensuring it is fully covered.
  • Paper and Books: Store books, paper, and boxes in dry locations to protect them from damage.
  • Fix Leaks: Check plumbing fixtures regularly and repair any leaks to reduce moisture.
  • Bathroom Ventilation: Run the fan during and after showers and wipe up any spilled water to keep the area dry.
  • Crawl Space Ventilation: Ensure crawl spaces are well-ventilated to prevent damp conditions that attract silverfish.
