Field Ant Infestations
Field ants rarely invade homes, though they can construct large nests in a resident's field or lawn. These nests, which lie low to the ground, can be eyesores and inconveniences when built along common walking paths. Furthermore, many Formica (a separate group under the Family – Fomicidae) are able to secrete formic acid against any perceived threat, making run-ins with the creatures potentially painful.
