Wolf Spider
Fast-moving ground spider that hunts without a web. Common in Ontario yards, gardens, and basements. Imposing appearance and quick movement make them seem more threatening than they are.
Body 10-35 mm, brown to grey with dark markings. Robust hairy body. Two large eyes prominent in front, with six smaller eyes arranged below. Carries egg sacs attached to the spinnerets; carries spiderlings on the back after hatching.
Lawns, gardens, mulched beds, woodpiles, basements, and garages. Active mostly at night but occasionally seen during the day. Do not build webs — hunt by chasing down prey.
Mildly. Wolf spiders can bite if handled or cornered. Bites are painful but not medically significant for most people. The bite site may swell and itch for a day or two.
Exterior perimeter treatment around the foundation, basement window wells, and garage entry points reduces wolf spider entry into the home. They also avoid the treated zone outside.
