From Steven Milloy's [link|http://www.foxnews.com/story/0,2933,60528,00.html|Junk Science column] at Fox News just last week:

DDT is also less toxic to humans than the alternative chemicals. That should be a boon to those who believe they are sickened by the spraying of the alternatives.

While I don't always buy into Milloy's ranting, I think he has a valid point here.
