Spiders control in Canada
Mostly harmless in Canada, but heavy webbing signals other pest activity.
How to identify it
Eight-legged, two body segments; house and cellar spiders are the usual indoor species.
Signs of an infestation
- Webbing in corners, window wells and basements
- Egg sacs in undisturbed areas
Is it dangerous?
Canadian house spiders are not medically significant; they are mainly a nuisance.
Can I handle this myself?
DIY may be reasonable
Regular vacuuming and de-webbing controls small numbers well.
When to call a professional
Call a professional for persistent heavy webbing, which usually means an abundant insect food supply.
Any pesticide used in Canada must be registered here and applied exactly as its label directs. We don't publish application instructions.
Typical professional treatment
De-webbing, perimeter treatment and reducing the insects spiders feed on.
Visits: 1–2 visits
How to keep them from coming back
- Switch exterior lights to warm LEDs that attract fewer insects
- Screen vents and window wells
- Reduce basement and garage clutter
