Preferred foods include grease, meats, cheese and peanut butter. Nests are very difficult to find, and these ants should be baited. Barrier treatments will slow the migration indoors and often force the ants into outdoor foraging patterns. These ants can be difficult to separate from Pharaoh ants but only have 2 segments on the antenna club. These ants feed on greasy foods including pet food and on sweets.
Nests are often under driveways or sidewalks or in other concealed sites.
Workers can be found in the kitchen. When swarms appear inside, the nest may be under a slab or similar location. Indoor colonies swarm at any time. If the nest cannot be found, baiting with a protein-based bait is most often successful. Barrier treatments will give seasonal control from outdoor colonies.
