The Argentine Ant

The Argentine Ant


The Argentine Ant

The Argentine Ant is classified as a severe pest throughout the Southeastern United States, as well as, other parts of the world. Introduced from South America, you can find an infestation is just about every home. Argentine Ants as workers, grow to 1/12 to 1/8 inches long. The Queen Argentine Ant is much larger, ranging from 1/6 to 1/4 inches long.

The worker ant from this colony is very aggressive toward other ants and will often eliminate any other ant in the area. This ant is well adaptable and can thrive in environments where other types of ants can not, which means this is the most common type of ant species in many locations.

The Queen Argentine Ant

Mating takes place within the nest. In most Argentine Ant colonies, there are many fertile queens present. When mating occurs within a nest, winged forms are not usually found.

The Queen Argentine Ant has many jobs inside their colony. Unlike most other Queen ants, they can be found doing the cleaning of themselves, and are very active in feeding and grooming the immature in the nest. Sometimes, in a colony with multiple Queen Ants, Budding may occur.

Budding: when some fertile Queens and a squad of workers become isolated from other colony members and establish a new colony.

The Argentine Ant Nest

Like most insects trying to survive, The Argentine Ant nest can be found close to both food and water sources. Their nests pop up in moist soil either next to or underneath buildings, along sidewalks, or beneath boards and plants.

You may occasionally find their nests within a structure, or in areas that are not soil related. For example, under bathtubs set on a slab foundation, in cracks of slabs, under insulation in an exterior wall, and even in potted plants and flower boxes.

The Argentine Ant Food Source

The Argentine Ant prefers their food to be sweet, mainly sugars, syrups, fruit juices, honeydew and secretion of plants. Workers forage for food along paths that extend out from their nest.  They also branch out systematically to explore in depth every area surrounding them. Their range of exploration may even flow over into the adjacent yard and home. You may find them start to enter houses when the weather conditions are either too wet or too dry.

The Argentine Ant Super-colonies

Despite the fact that the worker ants are aggressive to other types of ants, they are capable of noticing when their own species is in the area. They can coexist with their own species and frequently do so. Because the Argentine Ant is welcoming to their own species, their nests grow together and become super-colonies, meaning they can be extremely large cover a very massive area.
