Pavement ants are the small brown or black ants that march indoors each spring across the Greater Toronto Area. The colony lives in soil under patios, driveways and foundation cracks. They are a nuisance in kitchens. They do not excavate house framing the way carpenter ants do.
Usually not. The ants on a kitchen counter in spring are often pavement ants: small, and coming from a crack in the foundation. Carpenter ants are larger, often black, and more active at night, with sawdust near wood.
Under the patio, driveway or sidewalk, or in the soil against the foundation. The ants indoors are workers. The colony stays outside until the trail is followed back.
Often confused with carpenter ants.
