Zanti - Rodent-sized ant creatures sent to Earth for execution on episode "The Zanti Misfits" on the sci-fi anthology series THE OUTER LIMITS/ABC/1963-65. Landing in a remote rural area of the planet Earth, these six-legged aliens began to attack the nearby population. These hostile little critters were convicted criminals from the planet Zanti whose civilization had rocketed them to our world to be destroyed. It seemed their moral code prohibited them from killing their own kind. In the ensuing battle, these tiny but vicious criminals were stomped, and shot into extinction. I just love happy endings, don't you?
