Identifying Carpenter Ants: What Do They Look Like?

Carpenter ants are a common household pest that can cause significant damage if left unchecked. Unlike termites, which feed on wood, carpenter ants excavate tunnels and galleries in wood to build their nests. Identifying these pests is crucial for effective pest control measures. In this article, we will discuss what carpenter ants look like and answer some frequently asked questions about them.

What Do Carpenter Ants Look Like?

Carpenter ants are larger than most other ant species, with workers ranging from 6 to 13 mm in length. They have a segmented body with a distinct waist, elbowed antennae, and six legs. Their coloration varies depending on the species and can range from black to reddish-brown. Some carpenter ants may even have a combination of black and red colors.

Unlike termites, carpenter ants do not have straight antennae. Instead, their antennae have a distinctive bend or "elbow" in them. This characteristic is helpful in distinguishing them from other ant species.

Carpenter ants also have wings, but they are usually only visible on the reproductive individuals, known as swarmers or alates. These winged ants emerge during the mating season, and their presence may indicate an active carpenter ant colony nearby.
