Answer
Hi Randy.
You need to ask a nurseryman in your area.
I live in North Texas, and haven't see that type of critter.
There are so many burrowing insects, and small animals.
There are some wasps that burrow, and one of them is beneficial, because it feds on other harmful insects, but not sure which wasp it is.
Here is a good site for a lot of organic remedies fo insects etc.

Click on critter trouble at the top of the poage, and then on insects when you get to the critter trouble lage, and look for your bug.
You could look at sites to identify that hole by searching for,      insects of Ohio   in your search engine.
I put insects of Texas in mine, and got about 20 sites to look up. Some with pictures of the insects and their homes.
