Carpenter ants

Carpenter ants are a type of ant species known for their large size and their ability to nest in wood, often causing damage to wooden structures.  Winged, dark in color, and residing in moist, damaged woods, it's common that homeowners mistake carpenter ant swarms for termite colonies.

Size:   0.25 to 0.5 inches (6.35 to 12.7 mm)  in length.

Color:   Carpenter ants can vary in color, but they are commonly black or reddish-brown. Some species may have a combination of colors. 

Characteristics: Carpenter ants have a well-defined waist, elbowed antennae with multiple segments, prominent mandibles, and six legs with three distinct segments. 

Habitat and Behavior:  Carpenter ants are known for their habit of tunneling and nesting in wood. They do not consume wood but excavate it to create galleries for nesting. They primarily feed on insects, honeydew, and sugary substances. They can be found in forests, urban areas, and structures with wood components. Colonies are typically established by a single queen, and mature colonies can contain thousands of individuals. Carpenter ants can cause structural damage when nesting in wooden buildings.
