Argentine ant concrete walls, in spaces between boards and timbers, even among belongings in human dwellings. In natural areas, they generally nest shallowly in loose leaf litter or beneath small stones, due to their poor ability to dig deeper nests. However, if a deeper nesting ant species abandons their nest, Argentine ant colonies will readily take over the space. Austrian entomologist Gustav L. Mayr identified the first specimens of "Hypoclinea humilis" in the vicinity of Buenos Aires, Argentina in 1866.
