Cockroaches are revolting creatures, and I really do not see how wiping them out is going to upset the balance of our ecosystem. Not only are they filthy, what other animals eat cockroaches as part of their daily diet, and not out of necessity? Somehow, these critters have survived for so many thousands of years, and from what we read, they can also go through a nuclear fallout as though it was a walk in the park. The Japanese have other ideas though, drawing inspiration from this six legged pest with a robotic USB cockroach that can be remote controlled, and it also glows in the dark. Good thing it does not fly, otherwise it would be a major screamer inducer at any social setting!
