“Rover ants build their nests in both natural and disturbed habitats. Some of their preferred natural habitats include pine forests where nests occur in loose bark at the base of the pine tree’s trunk, beaches, mixed hardwood forests where they nest in soil and dead wood, plus prairies where they nest in soil, plant litter and grass thatch. In their urban habitat, they frequently nest in mulch and objects on the ground such as stones, bricks, landscape timbers and leaf litter. Also, rover ant nests can be found in potted plants.
The diet of rover ants consists of honeydew produced by aphids and scale insects and proteins from living and dead insects. Rover ants do not consume wood and do not cause structural damage to homes or other buildings. However, rover ants are known to be especially annoying since they readily infest homes, hospitals and businesses to forage and/or construct nests in wall voids. Fortunately, colonies are small – ranging from hundreds to a few thousands members.”
