It can be absorbed through the skin and is a typical representative of contact poisoning. In parts of the world with rising living standards, the elimination of malaria was often a collateral benefit of the introduction of window screens and improved sanitation. is that its extensive use in farm areas is most likely to upset the natural balances, not only killing beneficial insects in great number but by bringing about the death of fish, birds, and other forms of wild life either by their feeding on insects killed by D.D.T. [122] Others argue that the avoidance behavior slows eradication. [1][14] Even in 2010, California condors that feed on sea lions at Big Sur that in turn feed in the Palos Verdes Shelf area of the Montrose Chemical Superfund site exhibited continued thin-shell problems,[76][77] though DDT's role in the decline of the California condor is disputed. [47] In 1965, the U.S. military removed DDT from the military supply system due in part to the development of resistance by body lice to DDT; it was replaced by lindane.

In 1996, the country switched to alternative insecticides and malaria incidence increased dramatically. Structure and Synthesis of DDT. Strengthening malaria control while reducing reliance on DDT.
