SPIDERS - Info, Advice & Help

Local Expert Pest Control Guidance for Homes, Cottages & Businesses in Ontario

Quick Facts About Spiders

  • Most spiders in Canada are harmless and beneficial—they help control other pest populations.

  • Only a few species, such as the Black Widow, pose any risk to humans, and sightings are rare.

  • Spiders are typically more active indoors in fall as they seek warmth and shelter.

  • They do not infest homes like ants or cockroaches; most are accidental visitors.

Common Signs of a Spider Issue

  • Frequent sightings of spiders in corners, ceilings, or basements.

  • Webs appearing in windows, garages, or crawl spaces.

  • Egg sacs in hidden areas like under furniture or inside storage boxes.

Prevention Tips

  • Seal cracks and gaps around windows, doors, and foundation.

  • Keep clutter to a minimum, especially in basements and garages.

  • Use yellow or sodium vapor light bulbs outdoors—they attract fewer insects (and spiders).

  • Vacuum webs and spiders regularly; this helps reduce the population over time.

When to Call a Professional

  • You see large numbers of spiders in a short period.

  • You're concerned about venomous species (e.g. suspected Black Widow).

  • Webs are forming despite regular cleaning and sealing efforts.

  • You want safe, targeted treatment without harming beneficial insects or pets.
