Final cost depends on severity, property size, and treatment method.
Toronto has more raccoons per square kilometre than any city in North America. That is not a guess — biologists have been tracking them for decades. The Don Valley ravine system runs from the waterfront up through Leaside and into North York, and it functions as a raccoon highway delivering wildlife directly into residential backyards. In the Annex, raccoons den in the attics of 120-year-old Victorians where the original soffits have never been replaced. In Parkdale, mice pour into century semis through crumbling mortar joints every October. In Liberty Village and CityPlace, bed bugs move between condo units through shared plumbing risers faster than property managers can respond. Every Toronto neighbourhood has its own pest profile, shaped by housing age, tree canopy, and how close you are to a ravine.
Our Centipede Control Process in Toronto
Inspection
The technician identifies the prey insect population sustaining the centipedes: spiders, silverfish, cockroaches, or small ants. Moisture levels are measured throughout the basement and bathroom. Entry points along the foundation wall and around utility penetrations are mapped.
Treatment
The prey insect population is treated first — killing the food source causes centipedes to leave. Targeted insecticide is applied along baseboards, in wall voids, and at entry points. Crack sealing along the foundation perimeter prevents centipedes from re-entering from the exterior landscaping.
Prevention
Basement humidity is reduced through dehumidification and ventilation fixes. Entry points around windows, doors, and utility penetrations are sealed. A quarterly pest prevention program that controls spiders and other insects naturally keeps centipede populations low.
Signs You Need Centipede Control in Toronto
-
Fast-moving, multi-legged centipedes visible on basement floors, bathroom tiles, or basement walls at night
-
Centipedes concentrated in specific rooms: bathrooms, laundry rooms, or basement rec rooms
-
Other pest activity in the same areas — centipedes follow their prey insects
-
Damp, humid basement conditions with visible condensation on walls or windows
-
Silverfish, spiders, or small insects visible in the same areas centipedes are found
-
Musty basement smell — indicates excess moisture that both centipedes and their prey insects need
Why Hire a Professional in Toronto
-
Centipedes are a symptom of two problems: excess moisture and other pest activity. Treating only the centipedes without addressing the prey insect population and the humidity is a temporary fix.
-
Basement humidity in GTA homes with older foundations frequently exceeds 75%, which is the threshold centipedes need to survive. A professional moisture assessment identifies exactly where the problem is coming from.
-
GTA ravine-adjacent neighbourhoods in North York, Etobicoke, and Scarborough have higher centipede pressure from the natural environment. Properties in these areas need more robust exclusion and moisture control.
-
Centipedes breed indoors in damp conditions. House centipedes complete their entire life cycle inside, meaning an established population grows on its own without outdoor reinfestation.
-
A quarterly pest prevention program that controls spiders, silverfish, and other insects naturally reduces centipede populations by eliminating their food source.
