Common Signs of a Silverfish Infestation

Silverfish are nocturnal, elusive, and often hard to spot, but they leave behind certain telltale signs that indicate their presence.

Signs of Silver Fish

Identifying these signs early can help prevent a full-blown infestation, protecting your home or business from potential damage. Here we share the common signs to watch for.

Silverfish are small, silvery-grey insects with a teardrop shape and fish-like movements. They are typically 12–19mm long and are fast, darting away when disturbed. You may notice them around sinks, bathtubs, basements, and other damp areas, especially at night when they are most active.

They tend to be attracted to starchy materials and glue, which they consume for sustenance. Damage to books, important documents, wallpaper, and even clothing is a common sign of a silverfish infestation. Look for tiny holes or irregular, rough edges on paper items and fabrics, as well as yellow stains, which can indicate silverfish activity.

Their droppings are small, black, and pepper-like and are likely to be found in areas where silverfish are feeding or hiding, such as near books, boxes, or pantries. Silverfish also shed their skin as they grow, so you may find translucent, scale-like skin castings in damp, dark areas.

You may also notice slight yellow staining which may have been left behind on materials they have been feeding on. Typically found on infested cardboard, paper, or fabrics, which would be an indication that silverfish have been active in the area.

  • When to Call Vergo Pest Management
    While spotting a few silverfish occasionally may not indicate a serious problem, persistent signs of activity mean that an infestation may be developing. Here’s when it’s time to give us a call:
  • Repeated Sightings
    If you are frequently spotting silverfish, especially in multiple areas of your property, it’s likely they are breeding and hiding nearby.
  • Noticeable Damage
    Ongoing or worsening damage to books, wallpaper, clothing, or stored items is a strong indication that silverfish are actively feeding and multiplying.
  • High Humidity Issues
    If your property struggles with persistent humidity issues (such as damp basements or bathrooms), it can create ideal conditions for a silverfish infestation. Vergo can help identify the sources and provide guidance for moisture control.
  • Presence of Droppings and Shed Skin
    Finding droppings or skin castings in storage areas, basements, or other dark spaces suggests an established silverfish population that requires professional attention.

With Vergo Pest Management, you’ll benefit from expert assessment, targeted treatments, and long-term preventative measures to protect your home or business from silverfish damage. Acting quickly can make a significant difference in preventing costly repairs and safeguarding your property from further infestation.
