Formica Ants do not sting, but they can bite if threatened. Their greater defense comes from the formic acid they can spray from their abdomen.
Ants in the Formica genus have only 1 knob (bump) between the thorax and abdomen. They feed on the honeydew created by aphids (also in photo). The Formica Ant may actually act as a shepherd to the smaller aphids, moving them to an area of the plant so pull out the juices where the ant can then take the honeydew (juice) for itself.
This group of ants do not sting, but they can bite as well as spray formic acid from the tips of their abdomens. Colonies form in open grassland or under stones.
Professional exterminators should be contacted in the event of an infestation indoors.
