Overview

The pyramid ant gets its common name from the pyramid shaped structure on top of the thorax. They are found throughout the United States but are more common in southern regions. Mature pyramid ant colonies are usually small to moderate in size, each containing one or more queens and up to a few thousand individuals. When disturbed or crushed, this ant gives off a rotten-coconut odor.

Pyramid ants will bite if threatened, but are nonaggressive in nature.

Pyramid ants do not have a stinger, but workers will occasionally bite if there are perceived threats to the colony. Since they eat other insects, such as aggressive and invasive fire ants, some people consider them to actually be beneficial. However, due to their telltale diet, a large population of pyramid ants may signal that more dangerous ants are nearby as well. Additionally, although pyramid ants do not typically build nests indoors, they may enter households when foraging for sweets.

Pyramid ants usually nest in dry, open and sunny areas, such as lawns, pastures and sandy/bare areas. They can also be found underneath objects on the soil. Pyramid ant nests usually have a single entrance hole and are often built near the nests of other ant species , such as harvester ants. Mature pyramid ant colonies are usually small to moderate in size, each containing one queen and up to a few thousand individuals. Nest construction can result in cone-shaped mounds capable of ruining landscaping and making lawn care difficult. They are not known to nest indoors, but they will occasionally enter households in search of sugar-based foods . In general, pyramid ants are highly carnivorous and predacious, readily feeding on live and dead insects , including fire ants . Foragers are particularly fond of honeydew and will herd honeydew-producing insects such as aphids.
