Which type of ants can commonly be found in attic and wall voids?

Carpenter ants are commonly found in attics and wall voids due to their nesting behavior. Unlike other ant species that may build their colonies in soil or on the ground, carpenter ants create their nests primarily in wood, which makes attics and structural voids particularly appealing to them. They are known to excavate wood to create their nests, and this can often result in significant damage to wooden structures in homes, especially when left untreated.

In contrast, fire ants are typically found outdoors in soil, and they do not have the nesting habits that lead them to invade wall voids or attics. Pharaoh ants nest in hidden areas but are more associated with indoor environments where food is present, often not specifically in wall voids or attics. Argentine ants commonly build their nests in the ground or in potted plants and are not known for creating nests in the structural elements of houses. Overall, the nesting behavior and preference for wood make carpenter ants the most likely species to inhabit the hidden spaces within homes.
