What do Silverfish look like?

Silverfish have a flattened tear-drop shaped body with a long pair of antennae and 3 long bristle-like appendages coming off the back of their body. Their body is silver to brown in color, and they have silvery grayish scales covering their body giving them a silvery metallic appearance. Adult silverfish grow to be about ¾ of an inch in length and are not winged.

What are the signs of Silverfish?

Silverfish require a high humidity environment to live in; they can live without food for long periods of time, but cannot survive without humidity. Silverfish are most often introduced into a home or other building in boxes or piles of paper that are already infested and are brought inside; they will also enter into a home through cracks and crevices in foundations while foraging for food sources or a humid environment to live in.

Silverfish are nocturnal pests and move very quickly from location to location in a fish-like manner. During the day, silverfish will hide in basements, underneath sinks, in bathrooms, in kitchens, in laundry rooms, and in crawl spaces. At night when silverfish come out from their hiding spaces, they feed on paper, wallpaper, glue, clothing, dead insects, and food items like flour, cereals, and rolled oats.

What Damage do Silverfish cause?

Silverfish can contaminate food sources stored in homes. They can also cause damage to personal items like books, clothing, and papers by staining them yellow and eating small holes.

How do you prevent Silverfish?

There are some easy steps that homeowners can take, in addition to putting into place a year-round pest control program, to help prevent a silverfish infestation:

  • Reduce humidity levels by installing dehumidifiers in the high humidity areas of your home.
  • Routinely wipe out moisture from sinks and tubs and regularly vacuum your home to remove dust and hair.
  • Seal cracks and crevices found in your home’s foundation and/or exterior walls.
  • Install door sweeps underneath all exterior doors.
  • Store clothing and other items in sealed plastic containers instead of cardboard boxes; inspect boxes and packages for signs of silverfish before bringing them into your home.

How do I get rid of Silverfish?

Removing silverfish begins with taking preventative measures. Clean and declutter your house, reduce moisture, and seal all cracks to prevent additional silverfish from entering and will create environments silverfish do not like. To successfully remove all silverfish though, call a professional. These pests are good hiders and their dark color may make them difficult to find.

Can Silverfish hurt me?

Silverfish are not dangerous to people. They cannot bite and are not known to spread diseases. They can, however, contaminate food with their urine and feces.
