Pavement Ants in Ontario
Ontario pavement ant identification, nesting behaviour, indoor trail signs and practical prevention.

What pavement ants look like
Pavement ants are small brown to black ants that often travel in defined trails. They can be seen around cracks in concrete, foundation edges and ground-level entrances.
Where activity develops
Colonies commonly establish beneath pavement, slabs, stones and foundation areas. Workers may enter kitchens and lower levels while searching for food and moisture.
Signs worth documenting.
Small dark ants along floor edges
Soil displaced near cracks or patio stones

Prevention depends on correct identification and the conditions supporting activity. These steps are a practical starting point.
Identification before treatment
Similar-looking pests can require very different responses. Avoid applying a product until the pest, location and permitted label directions are clear.
