Yellow Jackets also will build massive ground hives too. I did a lawn one summer for a guy that had to recover from an accident involving a ground hive. He was mowing his lawn with a riding tractor and the whole tractor, with him on it, collapsed the ground right into the hive. He was stung several hundred times and was lucky to survive.
The most times I've ever been stung was 13 and they came out of a ground hive when I mowed over it.
