The short answer

All Corners Pest Control treats all ants in Hamilton homes, inside and outside, including carpenter, pavement, red and pharaoh ants. We search for the nest and treat it directly. If the nest cannot be found, we use a treatment that kills the workers or a slow-acting bait they carry back to the nest.

Ants in Hamilton

Hamilton’s older tree-lined streets below the escarpment come with mature trees, stumps and older wooden porches, which is exactly where carpenter ants like to nest. Pavement ants are everywhere there are driveways, walkways and patio stones, all across the city.

Ants usually show up inside in spring as the weather warms. A steady trail across the kitchen counter almost always means a nest close by, inside the walls or right outside the foundation.

How we handle it

  • Direct nest treatment when we find it, inside or outside
  • Baseboards treated through the house and around the exterior
  • Slow-acting bait for pharaoh ants or hidden nests
