　　The World Health Organization now supports the use of DDT in homes to control malaria. The agency supported indoor spraying with DDT and other insect poisons until the early 1980s. It stopped as health and environmental concerns about DDT increased.

　　But last Friday, an assistant director-general of the United Nations agency announced a policy change. Doctor Asamoa-Baah said indoor spraying is useful to quickly reduce the number of infections caused by malaria-carrying mosquitoes. He also stressed that DDT presents on health risk when used correctly.

　　The WHO says it supports indoor spraying in areas with high malaria rates, including throughout Africa. But its malaria program director, Arata Kochi, says DDT should be used only inside houses and huts, not outside and not for agriculture use.

　　In the 1940s DDT was found to be an excellent way to control insects. It cost little to produce and was not found to harm humans. So it was widely used for people and crops.

　　In the 1960s, environmentalist Rachel Carson and her book “Silent Spring” led to a movement to ban it. The United States did just that a decade later.

　　Yet the rise of malaria has led some environmental groups to change their thinking. The group Environmental Defense, which led the anti-DDT movement, now supports indoor use to control malaria.

　　But many critics of DDT worry it will not be used with great care. University of Illinois scientist May Berenbaum argues that DDT is not as effective as people might think. Writing in the Washington Post, she noted that some African mosquitoes developed resistance to it. She says DDT should be only one tool among many for insect control.

　　The WHO supports other interventions as well. But it says India sharply cut malaria rates in the past with indoor use of DDT. And ten countries in southern Africa are currently using it for malaria control.
