Experiments carried out over the past ten years (Jenkins, 1948), (Pasfield & Greaves, 1951) and (Forte & Greaves, 1953) have shown that modern insecticides are very effective in controlling the Argentine ant (Iridomyrmex humilis Mayr). Large scale experiments with DDT, aldrin dieldrin and chlordane showed that the last three materials were superior to DDT as barrier sprays and that the ant could be eradicated from quite large areas by the careful application of these chemicals. In an effort to test the possibility of successfully eradicating the ant from whole suburban districts and eventually from the entire State, a large section of South Perth and all the known infestations at Bunbury were sprayed during the summer of 1952-1953*.
