Little yellow ants invade homes and backyards as they forage for food. Extremely successful in displacing other native ant species, little yellow ants are found throughout Florida. Little yellow ants create super-colonies in small secluded areas like potted plants, twigs, and dead branches, and on small vegetation in landscaped areas.

Ant workers and queens feed on the nectar of flowers. Little yellow ants have been observed tending aphids and feeding on dead insects.
