In the 1940s and ’50s dichlorodiphenyltrichloroethane, a synthetic pesticide better known as DDT, was used to kill bugs that spread malaria and typhus in several parts of the world. DDT was argued to be toxic to humans and the environment in the famous environmental opus, Silent Spring. It was banned by the U.S. government in 1972.
Before all that, though, it was sprayed in American neighborhoods to suppress insect populations. The new movie Tree of Life has a great scene re-enacting the way that children would frolick in the spray as the DDT trucks went by. Here are two screen shots from the trailer:
