Silverfish are fast, elusive, and destructive to books, clothing, wallpaper, and stored food — and Surrey’s damp coastal climate makes them one of the most common household pests in the region. If you’re finding silverfish in your bathroom, basement, or bookcases, Top Line Pest Control offers effective silverfish control across Surrey, Langley, and the Lower Mainland. Call (604) 551-6504.
Signs of a silverfish infestation
- Live silverfish — fast-moving, silver-grey, teardrop-shaped insects 12–20mm long, typically seen at night in bathrooms, kitchens, or basements
- Yellow staining on paper, books, wallpaper, or fabric where silverfish have fed
- Irregular feeding damage — surface etching, holes, or scraped areas on paper, cardboard, and natural fabrics
- Small pepper-like droppings near feeding areas
- Shed skins — tiny translucent casings in dark, humid corners
What silverfish damage in your Surrey home
- Books, newspapers, and cardboard boxes — they eat the starch in paper and binding glue
- Clothing, linen, and natural fabrics (cotton, silk, linen) — they feed on fabric sizing and natural fibres
- Wallpaper — both the paper and the paste behind it
- Stored dry food — cereals, flour, pasta, and pet food in cardboard packaging
- Photographs and documents
Why Surrey homes get silverfish
Silverfish need three things: humidity, darkness, and starch. Surrey’s wet climate — wet winters, damp crawlspaces, and older homes with moisture issues — provides ideal conditions. They’re most common in:
- Bathrooms and laundry rooms with poor ventilation
- Basements and crawlspaces with moisture problems
- Attics where humid air collects
- Kitchen pantries near stored dry food
- Storage rooms with cardboard boxes
How Top Line treats silverfish in Surrey
- Inspection. We identify the main harborage areas and assess the extent of the infestation and the moisture conditions driving it.
- Targeted treatment. We apply residual insecticide to cracks, crevices, wall voids, and harborage areas — along with insect dust in attics, crawlspaces, and wall cavities where silverfish shelter.
- Prevention advice. We identify and advise on the moisture issues — leaks, poor ventilation, damp crawlspaces — that are sustaining the silverfish population. Treating without addressing moisture only provides temporary relief.

Frequently asked questions — silverfish control Surrey BC
Are silverfish harmful to humans?
Silverfish don’t bite and don’t transmit disease. However, their shed skins and droppings can trigger allergic reactions in sensitive individuals. Their primary damage is to property — books, clothing, and stored food.
Why do I keep finding silverfish in my bathroom?
Bathrooms combine the two things silverfish need most — humidity and darkness. Poor ventilation, dripping taps, and unsealed gaps around pipes all contribute. Improving bathroom ventilation and fixing any drips reduces the conditions that attract them, alongside professional treatment.
Can silverfish infestations spread through a whole house?
Yes. Silverfish spread through wall voids, plumbing chases, and gaps in flooring. A bathroom infestation left untreated will eventually spread to adjacent rooms, the basement, and any area with stored paper or fabric. Early treatment prevents this.
