Cornell University entomologist Jeffrey G. Scott sees a cockroach contraceptive as still
being a long way off. He may wish
to investigate such a product that has been very effective and on the market for years. I can
personally attest to its effectiveness. The common “flea bomb” that one gets from a veterinarian–the kind that you put in the middle of a room, close the door on, and let go–also sterilizes
any resident cockroaches. (You get two nuisances eliminated for the price of one.) The
lifetime of the roach apparently is about 30 days, because after that time, their population disappears.
