Argentine Ants in SE Louisiana and Mississippi
Argentine ants are an invasive species, with large trailing nests constructed near food sources. Found throughout Louisiana and Mississippi, Argentine ants are relentless, prolific breeders. They create huge colonies with multiple queens and millions of ants, pushing out other native ant species. If it is too dry or wet outdoors, they may enter structures in large numbers. Outdoors, they tend honeydew-producing species like aphids, however, Argentine ants will also forage into homes in search of sweets and greasy foods.
Argentine Ant Habitat
Argentine ants prefer to live outdoors, building nests in soil, underneath wood, debris, and at the base of shrubs or trees. However, to survive the winter, Argentine ants commonly move into protected habitats where temperatures are warmer. Indoors, nests are found in wall voids, bath traps, and insulation. Homeowners sometimes complain of massive numbers of dead ants found in unexpected places, such as bathtubs. When spring returns, Argentine ants move back into their preferred, outdoor nest sites where colonies grow steadily throughout the summer.
Argentine Ant Behaviors, Threats or Dangers
Although they don’t pose any serious health threats, the sheer population size of an Argentine ant colony is enough to disrupt anyone’s daily life. Most ants only deposit pheromone trails on their way back to the nest from the food source. However, Argentine ants leave behind pheromone trails to and from a food resource. This ensures that they are always covering new ground when searching for food. Because colony size increases quickly, they can rapidly form interconnecting colonies that can lead to a massive infestation. If an Argentine ant infestation is suspected, it is best to contact a professional ant exterminator.
