Behavior and Habitat of Argentine Ants
Workers are often present in large numbers and are moving in trails. Trails may be similar to White-footed ant trails, but Argentine ants are more slender and move more quickly so the trails may not appear as condensed. Workers may overwhelm outdoor eating areas, even entering parked cars.
Argentine ants have multiple queen nests with many widespread subcolonies containing millions of ants. They are usually found in heavily disturbed sites, but can invade natural environments. They nest in mulch, soil, near tree roots, in trees, in rotten wood, or even in garbage piles.
