The ban on using DDT in houses to fight malaria is an example of environmentalism that lost all sense of proportion.
The fact is that the quantities of DDT needed to be quite effective against malaria in tropical and other countries, where it is often at epidemic levels, is a tiny fraction of the amounts that had been used to rid crops of pesticides.

DDT was first banned from use in Norway and Sweden in 1970, but was not banned in the United Kingdom until 1984.

DDT is a persistent organochlorine pesticide and is largely responsible for the great decrease in the reproductive capabilities and consequently in the populations of fish-eating birds, such as the bald eagle, brown pelican, and osprey.
DDT [1,1,1-trichloro-2, 2-bis-(p-chlorophenyl)ethane] was (C.A.S. 50-29-3) one of the most widely used chemicals for the control of insects on agricultural crops and insects which carry diseases such as malaria and typhus.
Synonyms for DDE are DDT dihydrochloride; p,p'-DDE; dichlorodiphenyldichloroethylene; and 1,1-dichloro-2,2-bis(p- chlorophenyl)ethylene.

 gladwell dot com - the mosquito killer
The idea was to use DDT to kill only those mosquitoes which were directly connected to the spread of malaria--only those which had just picked up the malaria parasite from an infected person and were about to fly off and infect someone else.
DDT kills by attacking a mosquito's nervous system, affecting the nerve cells so that they keep firing and the insect goes into a spasm, lurching, shuddering, and twitching before it dies.
Not all of Carson's concerns about the health effects of DDT have stood the test of time--it has yet to be conclusively linked to human illness--but her larger point was justified: DDT was being used without concern for its environmental consequences.

 Planet Ark : Malaria study says safer alternatives to DDT
DDT is one of 12 persistent organic pollutants or POPs - dubbed the "dirty dozen" - that are targeted for restriction or elimination in a global treaty being negotiated in Geneva this week under the auspices of the U.N. Environment Programme.
Environmental groups say that DDT can travel long distances in the air and water, that it builds up in the fatty tissues of living beings, and that it stays in the sub-soil because it is not biodegradable.
WHO's position is that DDT can be used in the fight against malaria in a limited way," said Antero Aitio, a medical doctor at the chemical safety office of the U.N. health agency.

While noting that not all of Carson’s 1962 claims about the dangers of DDT have stood up to subsequent scrutiny, the author dismisses right-wing conspiracy theories like those in the first link, and makes the point that Carson was campaigning against the use of DDT as a broad-spectrum insecticide, not as an anti-malarial.
As this piece makes clear, the main reason for the abandonment of DDT as the core component in anti-malaria campaigns was the growth of resistance, which was of course exacerbated by indiscriminate use.
The ban on DDT use in developed countries, to the extent it had any effect, slowed the general rise of resistant species, and therefore increased the effectiveness of DDT in its anti-malarial use.

Donald Roberts, speaking for a coalition that is promoting DDT as a means of controlling malaria in developing countries, said the chemical was safe if sprayed in small amounts inside homes to repel mosquitoes that carry the parasite which causes malaria.
For many poor nations, DDT is the only affordable way to try to reduce the 500 million malaria infections each year, Roberts said.
"There is broad agreement that DDT should not be banned globally until we are absolutely convinced that the countries that are using it have affordable, effective alternatives," said Richard Liroff, director of the World Wildlife Fund's Alternatives to DDT Project.
