Carpenter Ant

Camponotus spp.

Characteristics

Carpenter ants are among the largest ants in Australia, ranging from 6mm to 12mm in length. They come in various colours, typically black, brownish-red, or a combination of both. They are known for their powerful mandibles which they use to hollow out wood. Unlike termites, they do not eat the wood; they simply excavate it to create galleries for nesting.

Habitat

In the wild, they nest in decaying logs, tree stumps, and hollow trees. In residential areas, they become a threat when they move into structural timber, especially wood that has been softened by moisture or decay. You will often find them in door frames, window sills, and roof voids.

Lifecycle

A colony begins with a single fertilised queen who establishes a "parent" nest in a moist outdoor location. Once the colony matures, it may establish "satellite" nests which often extend into nearby homes. These satellite nests contain workers and larvae but usually no queen.

FAQs About Carpenter Ant

Can Carpenter ants cause harm?

Yes, while carpenter ants don't eat wood, their nesting habits can cause significant structural damage over time. They can also deliver a painful bite if handled.

What are the signs of Carpenter ant infestation?

If you encounter "frass" (sawdust-like wood shavings) pushed out of holes, or notice a faint rustling sound coming from inside walls, you are most likely dealing with a carpenter ant infestation.

Where are the nests usually located?

The nests of carpenter ants are usually located in moist or damaged wood, such as areas near leaking pipes or poorly sealed windows.
