The Argentine Ant is extremely adaptable and tenacious and is a more persistent forager than any other species of ant. It can only be controlled by systematic spraying of infested areas. A spray barrier is laid around the edge of the infestation, and then all points where ants are found in numbers are sprayed - the base and rails of fences, the foundations of the house, the edges of garden beds, and so on. Finally, all open areas are sprayed in a grid pattern.
By following the large-scale methods outlined in this film, municipal and state authorities have virtually wiped out the pest from the Sydney metropolitan area, and from a 60 square-mile area in Western Australia.
