Don't worry probably what you are looking at is earthworm activity, they are part of organisms that recycle and make nutritious rich soil. But with ants [ANT] and termites it's a different thing though, also post pictures.

There is no grass registered as American grass.FIND out what you have.
The earth worm granules are the largest in size and those of ant mounds smaller depending on the size of ants.
