Answer: If you find excavations but no holes you may be dealing with a critter that is simply looking for grubs to eat. I have no idea which of a half dozen possibilities it might be. Moles spend their whole lives underground so it isn't likely they are responsible for the mounds of soil that do not also have entry holes. Scissors type traps are best for moles and gophers. You can set them in the main tunnels to trap the moles. Wish I had more to offer!
