These wasps are your friends. Besides, they don't have stingers.
However, wasps that look like this can be downright nasty...

We make friends with reptiles and arachnids, but less frequently with insects, unless they’re dead.
Those are the wasps that made my life miserable as a kid. They had a nest in the south side of the eaves in our OLD house (the bats had the attic) and they always found their ways into our bedroom and on occasion, into our beds.
