Silverfish in the House

How Do Silverfish Get Inside?

Fast-moving scavengers, silverfish find their way into homes in search of new food sources with some regularity. Silverfish are carrot-shaped and wingless, with flat, silver bodies as their name suggests.

The pest insects move quickly and can be found hidden under:

  • Rocks
  • Logs
  • Leaf litter outdoors

They can also make their way into homes accidentally.

Entry Points
Common entry points include:

  • Cracks in foundations.
  • Gaps in both windows and doors.

Other times, the insects enter homes as stowaways in boxes affected by moisture or even delivered during construction on green lumber.

Where Are Silverfish Found in the Home?

Common Silverfish Locations
Silverfish in the house are commonly found:

The nuisance pests regularly try to avoid light and will dart for areas of darkness when discovered.

Overly damp areas are perfect places to find silverfish such as:

  • Around plumbing pipes
  • Cellars
  • Basements
  • Bathrooms


Once inside, silverfish feed on:

  • Book bindings
  • Wallpaper paste
  • Linen drapes
  • Foods rich in starch

They can also be found taking bites out of various fabrics, including cottons, rayon, and silk, which leaves draperies, upholsteries, and linens susceptible to damage.

Silverfish populations left unchecked will result in noticeable damages and destruction to items made of paper or fabric. They are not known to bite humans or pets, nor do they spread disease.
