What Is Carpenter Ants?

The name of carpenter ants is derived from their habit of excavating wood to establish their nests. It is important to note that they do not consume wood, but instead create smooth tunnels by chewing through it. These ants are widespread throughout Australia.


Carpenter ants exhibit a polymorphic behavior, meaning that their worker ants can vary in size, and range in length from 1.3cm to 1.5cm. These ants are segmented and oval, have six legs and two antennae. They can be identified by their black to dark brown or brownish-orange colour.

Carpenter ants establish their nests in wood sources such as tree stumps, decaying fence posts, aged firewood, and beneath stones. The queen, eggs, and juveniles stay in the primary colony, which is typically located outside. Meanwhile, the workers, mature larvae, and pupae reside in satellite nests that stem from the primary colony. Over several years, these satellite colonies can be established indoors or outdoors.

After mating, winged males and females, also known as swarmers, mate during a brief flight. The male dies shortly after mating, and the queen sheds her wings and searches for a suitable nesting site. She prefers to nest in soft and moist wood of hollow trees, logs, or stumps. In the nest, the queen lays about 20 eggs that develop into adult workers in approximately two months.

The first brood of workers is tiny as they receive nourishment from the food reserves stored in the queen’s body. Subsequent broods are larger as they receive enough food from foraging workers. When the workers mature into adults, they take up the responsibility of foraging for food, enlarging the nest, and feeding and caring for the queen and subsequent larvae. Carpenter ants feed on dead insects, small invertebrates, and honeydew secreted by scale insects and aphids.

Carpenter ants have a diverse diet that includes plants, insects, honeydew, meats, sweets, and grease. Their worker ants can travel up to 90 metres from their nest to forage. These ants are primarily active during the daytime, specifically from before dusk until dawn.

Signs of Carpenter Ant Infestation

Observing large wingless black ants in and around your property is a potential sign of a carpenter ant infestation. But, it’s not a confirmation of their nests inside your home if found indoors. It’s possible that the nest is located outside, and the foraging workers enter your house to search for food and water. The worker ants tend to consume foods that are high in sugar and fat, as well as meats.
