Target the prey insects — the spiders follow.
Spider Control Ottawa
What you need to know
Spiders follow their food source. A proper spider program targets the prey insects at the perimeter, not just visible spiders inside. Ottawa's late summer and fall seasonal shift drives spiders indoors in large numbers — especially in older homes with gaps in window and door seals.
Warning signs
- ✓Webs in corners, window frames, and basement
- ✓Multiple species appearing inside in late August through October
- ✓Earwigs in damp areas — bathroom, basement, garage, or under mulch
- ✓Egg sacs in hidden corners or behind stored items

FAQ — Spider Control Ottawa
Why do I suddenly have so many spiders in fall?+
Ottawa's cooling temperatures in late August drive insects — and the spiders that eat them — indoors. A perimeter treatment in late August intercepts the wave before it starts.
Are Ottawa spiders dangerous?+
The vast majority are harmless. Yellow sac spiders can cause mild irritation. No dangerous species are established in Ottawa's climate.
How is spider treatment different from general pest control?+
Effective spider control eliminates prey insects first. Spraying only visible spiders provides short-term relief — the next generation moves in within weeks.
