To kill insects. It is a pesticide invented in 1942. "DDT was originally used during World War II to control typhus which was spread by the body louse. Since then it has been used to control mosquito borne malaria, and was used extensively as a general agricultural insecticide.
"Initially DDT was spectacularly successful particularly in the control of malaria, as well as against agricultural pests. But by the 1950s, resistance problems had developed, and during the 1960s, a number of serious environmental problems were identified leading to wide-ranging restrictions on its use .
In recent years numerous studies on DDT have shown its environmental persistence and its ability to bioaccumulate, especially in higher animals. Of particular concern is its potential to mimic hormones and thereby disrupt endocrine systems in wildlife and possibly humans."
