More about DDT:
The first of the current synthetic insecticides, DDT (dichloro-diphenyl-trichloroethane), was created in the 1940s. Malaria, typhus, and other human diseases spread by insects were the first to be successfully treated with it in both military and civilian populations.
Additionally, DDT worked well to control insects in homes, institutions, gardens, dwellings, and crop and livestock production. Due to DDT's widespread usage and early effectiveness as a pesticide in the US and other nations, many insect pest species have developed resistance to it.
