DDT (dichlorodiphenyltrichloroethane) is a powerful halocarbon insecticide with a controversial history. It is an extremely stable and decay-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. It's also toxic, in varying degrees, to things other than insects.
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 India still manufactures it. The Stockholm Convention was signed in 2001 to restrict the use of Persistent Organic Pollutants, of which DDT is the most well known (yes, DDT is organic — in the chemical sense of the word).
 DDT bans and mass murder
“”[DDT] should be used with caution, only when needed, and when no other effective, safe and affordable alternatives are locally available.
|—Brenda Eskenazi, explaining the scientific consensus on DDT|
Horrifically stupid wingnuts and experts for hire 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. The myth seems to have originated from the Competitive Enterprise Institute and from libertarian Roger Bate (and is promoted by his organization Africa Fighting Malaria).
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. DDT got banned in dozens of countries, but there was (and still is) no global ban on DDT; only agricultural use is almost globally 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.
Not only is DDT still approved by the WHO for use against malaria (in indoor residual spraying, which is the spraying of walls of a home so a mosquito landing after it bites should get a fatal dose), but the Persistent Organic Pollutants Treaty (POPs) has a special clause for DDT. Any nation may endorse the treaty calling for an end to DDT; but any nation may also use DDT at any time, for severe health reasons, by essentially writing a letter to WHO saying, "We have a health problem we think DDT may be useful to combat, so we're going to use DDT."
 The grain of truth beneath the bullshit
There were several aggressive — and often successful — attempts to get rid of malaria in places where it was endemic until then. Those attempts used DDT, as it was cheap and effective, and its negative effects were not yet known or understood. While there were huge successes in the 1950s, local factors, including the premature abandoning of efforts, led to a resurgence of malaria in places where it had been significantly decreased or on the brink of extinction. By the 1970s even the WHO had to admit that the program to globally eradicate malaria had failed, even though there were some remarkable successes. However, in no case was a successful eradication program stopped due to concerns regarding DDT.
