Late common wasps

We have had a continuous visitation of common wasps (Vespula vulgaris) on the east window of our sitting room for about a month.  They are nearly all males (distinguishable by the long antennae and body and larger size than the workers) and we get up to four or five a day.  I let them out and they sail away across the garden and, I suspect, we get newly emerged ones every day rather than yesterday's coming back again.  I have not yet worked out where they are coming from and we had rather few workers in summer.
It is not unusual for this species to be on the wing very late in the year, especially if the weather is mild, but it seems that there are a disproportionate number of males (we have yet to see a queen).
