Final cost depends on severity, property size, and treatment method.
North York spans a wide swath of Toronto's northern half, from the high-density corridors of Willowdale and Bayview Village to the quieter residential pockets of Bathurst Manor and Newtonbrook. Older post-war bungalows in Don Mills and York Mills are prime targets for mice and carpenter ants that exploit crumbling mortar and aging soffits. Raccoons thrive along the Don River ravine system that cuts through the district, regularly denning in attics across the area. The Yonge Street corridor hosts clusters of high-rise apartments and condos where bed bug and cockroach issues are prevalent. PestRecord connects North York residents with licensed pest control professionals who understand these varied neighbourhood conditions.
Our Silverfish Control Process in North York
Inspection
The technician uses a moisture meter to find the wet areas driving the infestation: leaking pipes, condensation on cold walls, poor basement ventilation, or water damage behind bathroom tiles. Silverfish need humidity above 75% to survive — moisture reduction is the foundation of control.
Treatment
Professional dust insecticide is applied into wall voids, behind baseboards, inside electrical boxes, and under bathroom tiles through small drilled holes. This reaches silverfish in their harbourage areas where surface sprays cannot penetrate. IGRs are applied to prevent juvenile silverfish from reaching adulthood.
Prevention
A residual insecticide is applied along baseboards, behind bathroom fixtures, and at entry points from the exterior. Dehumidification guidance is provided — maintaining basement humidity below 60% makes the environment hostile to silverfish and prevents their return.

Why Hire a Professional in North York
-
Silverfish infestations are driven by moisture. A professional identifies and addresses the humidity source that is sustaining the population, not just the silverfish themselves.
-
Surface sprays do not reach silverfish in wall voids and behind tiles. Professional void treatment with insecticide dust is the only way to eliminate the population hiding in the structure.
-
Silverfish can survive for months without food, so baiting is ineffective. Only direct void treatment and residual barriers work against established populations.
-
GTA older homes with stone foundations and limited basement ventilation are especially prone to silverfish. A professional identifies the specific moisture pathways driving the infestation.
-
Silverfish signal a moisture problem that, if left untreated, leads to mould, rot, and more serious pest issues.
