PEST CONTROL
Spider Control in Toronto & the GTA
While most spiders are harmless, infestations are unsettling and some species can bite. We treat entry points, basements, and crawl spaces to eliminate existing populations and prevent re-entry.
OUR APPROACH
How We Eliminate Spiders
Find What They Are Eating
Spiders concentrate where their prey concentrates, so a spider problem is usually a symptom. We identify the insect population sustaining them, because removing the food source does more than repeatedly clearing webs.
Treat Entry and Harbourage
Application targets the places spiders actually live and enter — foundation gaps, window frames, basements, crawl spaces, garages, and the sheltered exterior corners where webs are re-spun.
Clear Webs and Egg Sacs
Existing webs and egg sacs are removed rather than left in place. An untouched egg sac is next season's population, and clearing them makes it obvious whether new activity is genuinely new.
How to Identify Spiders
Most spiders found in Ontario homes are harmless — cellar spiders, cobweb spiders, and wolf spiders are the most common indoor species. Webs in corners, basements, and window frames are the clearest sign of an established population.
Seasonal Behaviour in Ontario
Spider activity increases in late summer and early fall as males wander in search of mates, which is when most indoor sightings occur. Populations concentrate wherever their prey — other insects — is most abundant, so a spider problem is often a symptom of a different pest issue.
DIY or Call a Professional?
Occasional single spiders can be swept up without concern. Recurring webs in the same areas, a visible increase in numbers, or finding egg sacs indicate an established population worth having assessed, particularly since treating the entry points and food source is more effective than repeatedly clearing webs.

COMMON QUESTIONS
Spider Control — Questions We Get
Are house spiders in Ontario dangerous?
Almost never. The species common in Ontario homes — cellar spiders, cobweb spiders, wolf spiders — are harmless to people and pets. The reason to treat is usually the volume, the webbing, and what the spider population indicates about other insects in the building.
Why do spiders keep coming back after I clear the webs?
Because clearing webs removes the symptom, not the cause. If the insects the spiders feed on are still present, new spiders keep arriving. Recurring webs in the same spots, rising numbers, or visible egg sacs all point to an established population worth treating at the source.
