Not the age of the thread , but you're probably talking about yellow
jackets . I know of no wasps that will nest in the ground . I have seen some
that built a paper nest partly under a rock , but nor under the ground . The
wasps we're most familiar with build a conical paper nest hanging from a
tree or underside of a beam or ceiling .
