Silverfish Identification

What are silverfish?

Silverfish are curious-looking insects that find their way into our homes, where they regularly startle us as they move quickly across the floors of our bathrooms, basements, or kitchens. The wriggling, fish-like motion in which they move and their carrot-shaped bodies covered in silvery scales gave these insects their name.

Though these insects have a name that would make you think they are at least partially aquatic, they are not. They have high moisture needs, and a lack of moisture outdoors often drives these pests into our St. Louis area homes. Two other identifying features of silverfish include long antennae and three long bristle-like structures that extend from their backends.

Are silverfish dangerous?

Silverfish are harmless to people, but they will feed on starchy materials and fabrics within our homes, making them a damaging pest. When in our homes, silverfish contaminate or damage things like:

  • Stored foods
  • Shampoo and toothpaste
  • Paper
  • Wallpaper
  • Books
  • Clothing
  • Upholstered furniture

Why do I have a silverfish problem?

Excess moisture in your home and a lack of moisture outside are likely the reason silverfish have become a problem in your house.

Things like leaky pipes, clogged gutters and downspouts, and dense vegetation growing next to your home's exterior cause a buildup of moisture in the soil that silverfish just can't resist. If the weather becomes hot and dry, they will migrate into our homes, seeking cooler, damper living conditions.

They will move into your home through spaces they find in the foundation, under doors, and through or around vents or basement windows.

Where will I find silverfish?

Silverfish that have moved into our homes will seek out areas that mimic their outdoor living conditions. Areas that often provide the excess moisture and food sources these pests are looking for include basements, bathrooms, kitchens, basements, crawlspaces, pantries, and cabinets under sinks.

Silverfish prefer to infest dark areas of a house, making it possible for these pests to live within a home for many months before you realize they're there.

How can I prevent silverfish in the future?

Take the time to make changes around your St. Louis yard and home to make it less attractive to silverfish and help prevent problems with these common household pests.

Below is a list of our most helpful silverfish prevention tips.

  • Inspect your home's exterior, patching any openings you discover in your foundation to keep silverfish and other pests out.
  • Place door sweeps on exterior doors to eliminate any space between the bottom of the door and the ground.
  • Use dehumidifiers and air conditioners to make the climate in your house less appealing to silverfish.
  • Declutter your house; silverfish regularly hide in things like boxes, stacks of papers, and stored clothing.
  • In your kitchen, remove as many stored foods from their original containers and place them inside plastic or glass containers with airtight lids.
  • Store clothing, blankets, and other fabrics inside large plastic bins with lids instead of cardboard boxes that are easily accessible to silverfish and other pests.
