Male-only predators to fight Kagman rats

I just read the article about rat infestation and I thought of a simple and logical idea. How about bringing in an animal that would hunt the rats down? But only bring in the male animals. This would solve a potential problem about breeding and the animal’s population getting out of hand. If there were only males, they would hunt, eat, get old, and well…die. Whether this idea is really logical or not, I just wanted to help out my home.
