Apropos the recent thread about heartworm preventative, here's an
interesting link to a recent article in the NYT

Quote: He and his team set up “dissemination stations,” consisting of
dark, damp cloths dusted with pyriproxyfen, in the nooks and crannies
of above-ground tombs in a cemetery. When a female rested on the
cloth, its legs picked up some of the pesticide, which came off when
it later landed in a breeding pool. The researchers found that putting
stations in as little as 3 percent of the available spots in the
cemetery resulted in coverage of almost all the breeding habitats in
the immediate area, and mortality of up to 98 percent of the mosquito
larvae.
