Field Ants: Identification, Habitat, Behavior, and Control

Field ants (Formica) are a common type of ant that can be found throughout North America. These ants are usually harmless, but they can become a nuisance if they start to invade your home or property. In this guide, we will provide you with everything you need to know about field ants, including identification, habitat, behavior, and control.

Field Ants

Field Ant Identification

Field ants are typically larger than other ant species, with workers ranging from 4-8 mm in length. They can vary in color from brown to black, and they have a distinctive two-segmented petiole (waist). Additionally, field ants have a single node between their thorax and abdomen, which distinguishes them from other ant species.

Field Ant Habitat

Field ants prefer to live in open fields and meadows, but they can also be found in wooded areas. They build their nests in soil, often creating large mounds that can reach up to two feet in height. These nests can be easily spotted in open fields and are usually surrounded by a bare patch of earth.

Field Ant Behavior

Field ants are not aggressive towards humans and do not sting. They are omnivorous, feeding on insects, nectar, and honeydew produced by aphids. While they are typically harmless, they can become a nuisance if they start to invade your home or property in search of food.

Additionally, sealing up any cracks or gaps in your home’s exterior can help prevent ants from entering.
