Mounds of earth look like nests could they be ants

Question

I have what I suspect are ant hills in lawn; how do I get rid of them and stop them from coming? Also, how do I know for sure they are ants?

Answer 1

I would watch the small hills to see if you can identify it as ants.
They would be visible moving in and out of the hole.
