small holes after rain
Ok experts. We had a good T storm Friday evening and about 1/2" of rain (judging from the clay saucer flower pot bottoms on my deck) and this afternoon I noticed small holes all in my lawn. My back yard has some common bermuda and some spots where I have put sod bermuda. The holes (a little larger than the diameter of a pen or pencil) were most prominent or visible where the sod is.
There were probably 15-20 holes per square foot, or maybe more. What critter made these holes? Could I be so lucky that they were earthworms? OR unlucky that grubs did this?
Any ideas? I'll check it out again tomorrow and see if I can get a picture.
