Black ground beetles are a good natural control for cutworms. I think there are several species of the beetles all commonly called 'black ground beetles'. If you handle them they kind of put off a strong odor that reminds me of ammonia, so I've called them ammonia beetles since I was a kid. In my experience, they do a good job of getting rid of cutworms. I was having a problem with cutworms and my place of employment had a nuisance problem with the beetles, so I started bringing them home and releasing them. You could see them dragging a cutworm around in the middle of the day.
