A silvery, fish-shaped insect darting for cover the moment you flip on a bathroom light in a Burnaby or Vancouver home is a silverfish, and by the time you spot one, it’s usually been active for a while. Silverfish are nocturnal and genuinely fast, which is why sightings are rare even in an established infestation — most of the evidence people actually notice is the damage left behind: thinning pages and chewed bindings in books, yellowish stains and small irregular holes in wallpaper, or fine scale-like droppings tucked into cracks and cabinet corners.
What makes silverfish stubborn is their dependence on moisture. They can’t survive without consistently damp conditions, which is why they cluster in bathrooms, basements, laundry rooms, and any crawl space in a Coquitlam or Richmond home with poor ventilation or a slow leak. Spraying visible insects without addressing the humidity behind them rarely holds — new silverfish simply move into the same damp conditions within weeks, and a single female can lay dozens of eggs tucked into cracks where they go completely unnoticed until they hatch.
We start by identifying the moisture sources actually sustaining the population — a leaking pipe, poor bathroom ventilation, a damp crawl space — since treating silverfish without addressing that source is only a temporary fix. From there we apply targeted crack-and-crevice treatment to hiding spots in bookcases, closets, baseboards, and cabinet voids, paired with practical recommendations for reducing humidity long-term.
