Carpenter ants are the largest of the Maine ant species and come in two varieties: black carpenter ants and red carpenter ants. Black carpenter ants are the more common of the two in Maine and can become problematic, especially if signs of infestation are ignored.

Even though carpenter ants play a positive role in the environment, such as returning dead wood to the soil, man-made structures are not exempt from invasions, which can become costly. The reason being, unlike termites, carpenter ants do not eat sound wood. Instead, they chew out sawdust-like pieces, creating a nest to live in and raise their young.

Consequently, these ants will then leave their nest inside the structure while they search for food, especially if there is a kitchen nearby, and expand their nest size. However, the biggest issue is the effect their excavation has on the structure of a property, which can become expensive to repair.

Additionally, Cornfield ants nest in soil under stones, bricks, sidewalks and other concealed sites, as well as rotting logs and stumps.


Because European red ants aggressively defend their territory, they can become a nuisance to people and the environment. These ants readily sting humans, pets and livestock that move slowly or rest on their territory. Once they have established a nest, most property owners find it hard to use their land because of the constant stinging. Even though these ants do not nest indoors or create large soil mounds, it is important to identify the nesting area to avoid serious infestation.European red ants, also known as European fire ants, are closely related to the “true” fire ants in the Southern U.S. and Latin America. They are the most invasive ant species found in Maine, especially in many communities along the Maine coast. These ants have taken advantage of the local habitat, including lawns, old fields, shrubs and the deciduous Maine forest.
