Small holes about the size of a nickel in my yard
There are several small holes in my yard. Never seen them before. They're about as big around as a nickel or so, not a mound of dirt, just a hole. We have 2 dogs and we have not seen any creatures. I am in Richmond, VA if that detail helps. We have 2 pear and 1 peach tree but nothing is producing yet. What is it? I am worried, as they look just like the picture on your website.
This could be birds, earthworms, insects, or solitary bees.
Small snakes can also be the culprit.
I would contact your local County Extension Office for a list of insects or animals that are common to your area.
