Looks like Mole holes. Drop some hot pepper down the holes, the culprits will reveal themselves.

Didn't know this. I have moles all over my yard...little suckers make raised tunnels everywhere. I'll have to "pepper" them and see what happens.

You obviously have a Hobbit problem....Just leave the little blighters a cold mug of ale,a large meal (with wild mushrooms) and some smoke...they'll move on!

If moles are makin'mincemeat out of your lawn,let 'em chew on this!

If you want to foil those dastardly moles that are having a grand ol' time in your yard at your expense,insert sticks of unwrapped gum,slit lengthwise, into theirs runs. The critters will eat the gum,but they can't digest it,so they'll disappear for good.

P.S.Don't just use any old gum----only Juicy Fruit will do! Good luck.

How close to water do you live?

 

Looks alot like crawfish holes, except I don't see the little beads of mud that would typically assure thats what it is.

What about those things in post #35? Could that be what you're talking about.

 

And we don't live very near water. There is a reservoir, but it's a block from here, and then down a long driveway.

#35 doesn't show me as much as #37.... 37 is what makes me think it may very well be crawfish. The distance of the reservois is still condusive to the crawfish burroing there. It's not so much the direct ability to get in the water, but their ability to get down to the water table.

 

Crawfish typically roll little round mud pellets when they dig holes. If you go out late at night on a damp night with a spotlight, you may be able to determine who your culprit is if in fact it is a crawfish.

A friend has crawdads with no stream in sight. We dug down one time, and found an underwater stream. It sounds like a waterfall when you put your ears up to it.

 

I have similar holes in my backyard, which is a huge problem because it is a 100% Midnight Bluegrass field hockey field for my daughter. First I thought they were bees, which I had a few years back and they make the same size holes as yours. Mine turned out to be earthworm holes this time though. The main entrances can be up to 2 inches across, and you'd never think they were from worms. They are wrecking the field which needs to be putting green flat, and they leave small "casts" which mae the turf too bumpy. Some nights I would find 50 new holes.

I really don't think it's crawdads. It needs to be a low lying section that stays wet and rather swampy. Usually so much so that it is difficult to grow grass on it. Not likely a suburban lawn setting. Notice how the mud is rolled up on the sides of the crawdad excavation. I still think it's skunk.

I think I agree with you all the way around.
