Are cockroaches helpful

Answer 1

http://www.sciencedaily.com/releases/2008/01/080106132313.htm "For several years, ARS entomologist Bob Pfannenstiel has been studying predators that feed on the eggs of lepidopteran pests of annual crops. Pfannenstiel, who is in the Beneficial Insects Research Unit at Weslaco, Texas, does most of his work on cotton and the pests that plague it, such as bollworm and beet armyworm. In the summer of 2006, he discovered a new predator that feeds on lepidopteran eggs-the Asian cockroach, Blattella asahinai. This roach was observed in large numbers-up to 100 or more per square meter-in soybean fields at Weslaco, yet it causes no damage to the soybeans."

Answer 2

Cockroaches help nature by recycling decaying matter in nature, feeding many various predatory species in the wild, teaching us how to cure many illnesses, and even helping us to construct artificial hearts designed after the ever-efficient anatomy of our friend, the cockroach. They do far more good for us and the world than bad, as only about 30 of the 4,000+ species of cockroach are known pests to humans, and the only diseases they give to us come from our own filth. Roaches themselves are very clean, and if it weren't for the diseases they carry from our garbage to our kitchen utensils and food... the worst they do to people is cause childhood Asthma in some asthma sufferers.
