Carpenter ants are among the larger ant species. They vary in length from 0.5 to 2.5 cm long. The most common types in Canada are black or reddish brown.
It takes a carpenter ant around 2 months two grow from an egg to an adult. The queen of the colony usually lays thousands of eggs, and fertile females go on to establish nearby colonies of their own, hence expanding the infestation.
Carpenter ants live in large colonies of thousands of ants. Mature colonies can have thousands of ants. Carpenter ants build their nests by carving wood. Therefore an untreated infestation can over time cause damage to wooden structures, including serious structural damage in houses.
A pavement ant is around 0.3 cm long, and is dark-brown in colour.
The pavement ants usually build their nests under pavements and driveways.
