Silverfish thrive in humid, dark spaces — bathrooms, basements, closets — feeding on starches in paper, book bindings, wallpaper glue, and cardboard, and can go months between feedings while staying well hidden.
Left unchecked, silverfish can damage stored documents, books, and wallpaper, and their presence usually points to a humidity level worth correcting.
We treat active harbourage areas and recommend humidity control — a dehumidifier, improved bathroom ventilation — since reducing moisture is what stops silverfish from establishing long-term.
Silverfish control across Toronto, Durham Region, and York Region, including North York, Thornhill, and Maple. Call (647) 945-9602.

No, they're not known to spread disease or bite — the concern is property damage to paper, books, and fabric.
Bathrooms are typically the most humid room in the house, and silverfish need high humidity to survive.
It significantly reduces the conditions they need to thrive, and combined with treatment it's an effective long-term fix.
