Yesterday, our ant specialists were dispatched to a call in Pickering for pavement ants. Upon arrival, they discovered over 20 small colonies had spread out over the patio. Pavement ants are little black ants which nest can nest inside cracks in interlocking brick and concrete. Primarily they are found in patios, walkways, driveways and foundation cracks. An exterior bait service was provided using multiple baits. Ant bait works by attracting foraging ants who bring the bait back to the queen, eventually killing her and the rest of the colony.
