Hi,
There are several small 1-2 in holes in my lawn. They seem to be shallow, I don’t see a tunnel. In one of them I saw an earthworm in the ground. Also, I have small mounds with tiny holes on top that are shaped like anthills. Can you confirm for me, please? I would appreciate it so much!

Expert Response
The holes you see are probably from nightcrawlers or earthworms. The small mounds are from ants. Neither are a risk to your lawn. You will find that some publications recommend vertical mowing to level the lawn. We are not recommending that this year because of the drought. Our lawns are too stressed to stand up to that procedure. Here is a link:What's wrong with my plant? : Garden : University of Minnesota Extension (umn.edu)
