Black Carpenter ant

Black Carpenter ant

Camponotus pennsylvanicus

A species of Carpenter ants, Also known as Eastern carpenter ant, Black ant

The black Carpenter ant (Camponotus pennsylvanicus) is given that name from their tendency to chew wood to build their tunnels. They are considered a major pest who can chew through building support beams in the worst-case scenario. Black Carpenter ants produce "aphid farms." The ant cooperates with aphids by protecting them while the aphid produces sweet dew that the ant uses to survive.

The queens and the largest workers (also called super majors) are quite large and are some of the largest ants found on the North American continent. As with all ants, the antennae are elbowed.

How to Identify Black Carpenter ant?

Life Cycle of Black Carpenter ant
Egg The initial stage, where a small, oval egg is laid by the female black Carpenter ant. Often tiny and whitish, the egg is difficult to see and remains static, starting the life cycle.
Larva Upon hatching, the larva is worm-like, lacking legs and eyes. It is mostly immobile, voraciously consuming food provided by adult black Carpenter ants for growth and molts several times.
Pupal The larva transforms into a pupa, ceasing to eat. This stage sees the black Carpenter ant developing definitive adult structures within a cocoon-like silk or bare. Color and form begin to differentiate.
Adult Emerging from the pupa, the adult black Carpenter ant's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

Habitat Preferences of Black Carpenter ant Through Different Life Stages
The eggs of black Carpenter ant are generally found within the hidden chambers of the nest, often located in decaying wood or underground. Larvae are nurtured in similar secluded nest chambers, where workers tend them diligently. Pupae, like the previous stages, develop within the safety of the nest, protected from predators and environmental extremes. To locate these stages, one typically needs to carefully dissect a nest, taking caution not to disrupt the colony structure. Adult black Carpenter ant, in contrast, are commonly visible outside the nest foraging on the ground, on plant materials, and sometimes indoors, where they seek food and water — making adults the most accessible stage for observation.

Bite Humans

Black Carpenter ant typically do not bite humans unless their nest is disturbed. In such cases, adult workers may bite defensively, using strong mandibles, but the effect is usually mild due to the absence of a venomous sting. Consequences are minor discomfort and, rarely, small abrasions.

Structural Pests

The black Carpenter ant can cause severe damage as both adult and larval stages share a penchant for carving galleries into wooden structures. This includes houses and furniture, leading to potential structural failure and costly repairs. These insects can silently degrade property integrity, causing considerable inconvenience and financial loss for homeowners.
