David Hill muttered:

If the wasps are not bothering me and mine then live and let live,
About 4 years ago we had a beautiful wasps nest in a large Viburnam Placatum
.. it was out of the way so it stayed.

We have a wasp nest under the thatch of the porch, I decided to let it be
and so far have had virtually no houseflies in the house, whereas in
previous years they'd be everywhere... together with the almost plague
proportions of hover flies that have eaten all the aphids, they've done a
great job.
