DDT is hardly benign. You also imply that use of DDT is banned worldwide, thus allowing malaria to spread unchecked, when in fact many, and perhaps most, of the countries where malaria is a problem permit use of DDT. But its effectiveness against mosquitoes carrying malaria is hardly a justification for its use in the US, where malaria is not a threat. So I do not quite understand what your point is. Is it that we should resume use of DDT in the US? If so, why?

Allow me to add to my previous post, this information from Wikipedia:

[T]he ban on DDT did not significantly interfere with its use as an anti-malarial agent; malarial deaths remain depressed in most of the world, except for Africa, where they have been climbing steadily since 1900. The World Health Organization attributes most of the increase in malarial deaths to insect resistance to pesticides (like DDT) and malaria pathogen resistance to drug treatments, in addition to generally poor health of much of the African population.
