Mulder and Scully arrive on the scene when a small town is seemingly targeted for extinction by a swarm of killer cockroaches. As the case unfolds, the agents reach the seemingly inescapable conclusion that the tiny scourges are visitors from another planet. The climax of the story invokes chilling but nostalgic memories of Orson Welles' classic radio broadcast of "The War of the Worlds," courtesy of scriptwriter Darin Morgan -- with a truly pungent twist at the very end. "War of the Coprophages" was originally telecast January 5, 1996.
