DDT has for long being considered a wonder chemical since its use increased after the Second World War. DDT became preferred in fighting insects because it is very toxic to the nervous system. It was advantageous over other chemicals because it is also harmless to humans, which means it can be used to control insects without inflicting health damage to humans. During the Second World War, DDT was sprayed in landing sites in order to protect Allied troops from insects like lice and others. It was successfully used to control spread of an epidemic of typhus-carrying lice. DDT was also successfully used to combat yellow fever, typhus, and elephantiasis by controlling insects that caused these diseases. However, the most successful use of DDT was recorded in control of more than 60 species of mosquito that carries malaria parasite (Easton, 2005). DDT normally kills mosquito on contact. It has been used in combination with other measures like draining of swamps, spraying DDT, and others. DDT is not only used in developing countries but it is also used in developed countries like U.S, Europe, Japan, and Australia which have incidence of malaria. Indeed, DDT has been quite effective in eradicating malaria. In India, it reduced the number of deaths related to malaria from 800,000 to zero in 1960s. In Sri Lanka, it reduced deaths from 2.8 million to only 17.
