Newsweek magazine, even in its much reduced form (bolstered by a good on-line site), still provides essential reporting.
- DDT doesn’t work against bedbugs, and hasn’t worked against them since the late 1950s.
- Astroturf organizations, so-called “think-tanks” set up by corporate interests jumped on bedbugs as another way of attacking the 46-years dead Rachel Carson, environmentalists, scientists and government — falsely. The Heartland Institute is singled out as one group spreading false claims in favor of poison and against environmental protection.
- The recent resurgence of bedbugs is more related to changes in fighting other pests than in the discontinuation of DDT against them. Had DDT been the magic answer, bedbugs should have made a resurgence in 1960 when DDT use against them was stopped, not 2010, a full half-century later.
- The many screeds in favor of DDT are politically driven, not science driven.
Think about that — every claim that we need DDT to fight bedbugs is a planted, political advertisement, and not a fact-based policy argument. Each of those claims is based in a political smear, and not based on science.
The really weird part is that so many writers and bloggers spread the false claims without being paid. Selling one’s soul for money is understandable; giving one’s soul away for nothing is stupid, or evil, or both.
DDT “devastated” bedbug populations when it was introduced in the 1940s, says Richard Cooper, technical director for Cooper Pest Solutions and a widely quoted authority on bedbug control. Mattresses were soaked in it, wallpaper came pre-treated with it. It also killed boll weevils, which fed on cotton buds and flowers (by far, the majority of DDT was applied to cotton fields), and, incidentally, it killed bald eagles and numerous other species of birds, the phenomenon that gave Carson her title. In the laboratory, DDT can cause cancer in animals; its effect on human beings has long been debated, but since it accumulates up the food chain, and stays in the body for years, the consensus among public-health experts was that it was better to act before effects showed up in the population. But long before the United States banned most uses of it in 1972, DDT had lost its effectiveness against bedbugs—which, like many fast-breeding insects, are extremely adept at evolving resistance to pesticides. “Bloggers talk about bringing back DDT,” says Bob Rosenberg, director of government affairs for the National Pest Management Association, “but we had stopped using it even before 1972.”
