Argentine Ants (Linepithema humile)
Argentine ants are an invasive species forming massive supercolonies that can stretch for miles, outcompeting native ant species and overwhelming homes in search of food and water. They are known for their aggressive foraging behavior and ability to establish trails quickly inside structures. Unlike many ant species, Argentine ants have multiple queens, making colony elimination particularly challenging. Professional baiting programs exploiting their social feeding behavior provide the most thorough control.
