Need help with ground hornets

[DUCKGOGETTER]

Just talked to my father-n-law and he told me that he was cutting the grass on the road at our blind and he ran over a ground hornets nest. He said there was 100's if not 1000's of hornets and some how by the grace of god he didn't get stung. My question is i don't even know where to begin to get rid of these things, and to be honest with you i really don't even want to handle it myself. Any info would be greatly appreciated.
