Fill a water bottle with one part dish soap and two parts water, then shake it up to mix the solution thoroughly. When you see a line of ants (or just one ant, for that matter) spray the mixture over them. If they are Argentine ants they’re not going away.
Argentine ants are not native to the United States. They were introduced to the US probably on coffee ships from Brazil and Argentina through the port of New Orleans sometime before 1891. They spread rapidly on commercial shipments of plants and other materials. Now Argentine ants are found throughout most of the southern states and California, with isolated infestations in a few other areas.
Argentine ant populations have exploded around the state in the past century. Their huge colonies threaten native ants, plague madden homeowners as they flood into kitchens. If you have a household ant problem, it’s probably Argentine ants.
