Argentine ants

These ants have been introduced to the whole world. Only native to northern Argentina, Uruguay, Paraguay, Bolivia and southern Brazil, argentine ants hold the strongest colonies of all. Take carpenter ants (Camponotus) for example. They only expand to thousands but how can a few thousand survive against millions? Once the argentine ants surround and externimate the defenders, they take the nest over. One of their predators is the red imported fire ant.
