Like most ants, Argentine Ants will eat just about anything; favorite foods include meat, oil, sweet things, and even eggs. Argentine Ants have complex foraging habits and will explore multiple food sources before returning to the nest; most ant species will transport food in a direct line from the food source back to the nest. This particular food-seeking behavior makes it easy to distinguish Argentine Ants from other similar looking species.
Rotten wood, mulch, and loose soil are the preferred nesting spots of Argentine Ants. Since multiple queens may be present in a population, sub-colonies will be constructed adjacent to the main nest. Shallow mounds up to two inches high identify the entrances to an ant nest.
