Black Carpenter Ant

Natural Habitat

Nests are typically found in moist or decaying wood, including tree stumps, logs, and structural timbers of buildings.

Diet & Feeding

Omnivorous; they consume plant juices, honeydew from aphids, other insects, and sugary or protein-rich household foods.

Behavior Patterns

They are primarily nocturnal foragers. Unlike termites, they do not eat wood but excavate smooth galleries within it to house their colonies through a complex social hierarchy.

Risks & Benefits

Risks include significant structural damage to wooden buildings. Benefits include their role as decomposers, breaking down dead wood in forest ecosystems and preying on other insect pests.
