Why spider problems often indicate a larger issue
Spiders do not feed on crumbs, standing water, or stored food the way many other pests do. They feed on insects. When spiders are consistently present in a home or business, it typically means there is a reliable source of prey already inside the building. Flies, moths, ants, silverfish, and other small insects are all prey species for common Ottawa spiders. A spider problem, in many cases, is a symptom of a broader insect issue that needs to be addressed at the same time.
Common spiders found in Ottawa properties
A range of spider species can be found in Ottawa homes and commercial spaces throughout the year:
- Cellar spiders build loose, tangled webs in basements, crawl spaces, and other damp, low-traffic areas where they can remain undisturbed
- Funnel weavers create flat, funnel-shaped webs in corners of garages, window frames, and along the base of exterior walls
- Wolf spiders are ground-hunting spiders that do not spin webs; they are commonly found at ground level near doors, in basements, and along baseboards
- House spiders spin irregular webs around windows, in ceiling corners, and behind furniture
- Fishing spiders are sometimes found near water sources such as basement drains or utility rooms
Clutter, stored materials, and seldom-disturbed areas provide harborage for spiders. These conditions should be addressed alongside any treatment program.
How our spider control service works
We start with an inspection to identify the species present, locate active web-building areas, and look for signs of the prey insects that may be sustaining the population. Treatment typically includes application to baseboards, window frames, entry points, and other areas of activity. Exterior treatment along the foundation, around door and window frames, and at utility penetrations can reduce the number of spiders and insects that enter the building in the first place. We also recommend sealing visible cracks or gaps in the exterior as part of a longer-term prevention strategy.
Spider control for Ottawa homes and businesses
We provide spider control in Ottawa for houses, condos, basements, garages, and commercial properties. Spiders are most active in late summer and early fall as they seek shelter from cooling temperatures, but indoor populations can persist year-round. For businesses, webs near customer-facing areas may indicate an ongoing pest problem that warrants a thorough inspection.

Frequently asked questions
Are Ottawa spiders dangerous?
Most spiders in Ottawa are not medically dangerous, but some species like the northern black widow can be found occasionally. A professional inspection helps identify whether a concerning species is present.
Why do I have so many spiders in my home?
Spiders follow their prey. High spider activity often indicates an underlying insect problem inside the property. Treating the prey insects can reduce spider populations over time.
Can you treat both inside and outside the property?
Yes. Exterior treatment along foundations and entry points can help reduce how many spiders and insects enter the building.
