Understand what
you’re seeing.
Pavement ants are one of the most common ants inside Toronto homes. They nest in soil under sidewalks, driveways and building slabs, and follow trails indoors looking for food.
Identification & signs
- Pavement ants are small, dark brown to black ants. Workers are all roughly the same small size.
- Colonies are usually located under sidewalks, building slabs and large rocks. Small piles of displaced soil in pavement cracks are a common sign.
- Winged reproductives usually swarm in spring, but in heated buildings they can emerge at other times of year, including late fall and winter.
- Indoors they forage for a wide range of foods, including sweet, greasy and protein-rich residues.
Identification reference: Penn State Extension: pavement ant.
Practical first steps.
Start with the conditions you can observe. If the activity continues or the pest is uncertain, describe the pattern when requesting an assessment.
- Clean crumbs and spills, especially along baseboards, under appliances and around pet food bowls.
- Store food in sealed containers and take out kitchen waste regularly.
- Note where the trail enters: slab cracks in the basement, gaps around doors, or expansion joints near the foundation.
- Photograph soil piles in nearby pavement cracks; they help locate the colony.
