DDT (dichlorodiphenyltrichloroethane) is a powerful insecticide with a controversial history. It is an extremely stable and resistant chemical: the discoverer found that jars that had contained DDT and were subsequently autoclaved still had enough DDT residue in them to kill insects. A little goes a long way.
DDT use was restricted and then banned in most Western countries in the 1960s and '70s, and in those countries where it remains legal, it is only used as a health measure to control the mosquitoes that spread malaria. Only China and India still manufacture it.
 DDT bans and mass murder
Wingnuts (Lee Doren from the YouTube channel "HowTheWorldWorks" is one example) and corporate shills will sometimes imply that a supposed worldwide ban on DDT has killed millions of people by giving them malaria or some other mosquito-borne disease, and that Rachel Carson's book Silent Spring was responsible for the alleged ban. There's even a site run by the right-wing think tank Competitive Enterprise Institute titled Rachelwaswrong.org This is total rubbish. Carson devoted some of her book into weighing the pros and cons of DDT use, but her findings did not lead to a global ban. There was and is no global ban on DDT; only agricultural use is banned. Places with deadly mosquito-borne illnesses still use DDT, and in some places excessive use has led to the development of DDT-resistant mosquitoes. In fact, the drastic reduction of DDT use in agriculture delayed the onset of resistance in mosquitoes.
