Other villagers object to DDT spraying because it does not kill cockroaches[13] or bedbugs;[12]

I'm not sure I believe that. At least residual DDT seems to have done a good job killing bedbugs in the States, at least until it final completely "washed out" of the system a couple of years ago.

Also wikipedia is notoriously unreliable on any vaguely political topic, probably more so then well-known explicitly political topics. The latter attract enough attention that the NPOV policy is actually applied, whereas the former wind up getting "adopted" by some mind-killed administrator with an axe to grind.
