And Yet More Wasps

So the wasp man came back, after a few squirts he concluded that the nest must actually be within the down pipe from the gutter.

It was at this point that the dishwasher repairmen arrived, they were going "oh, it's a Bosch" and telling me that it wasn't worth fixing (they didn't charge me anything, so that's alright) - don't get one with a digital display the steam corrodes the solder connections, apparently.

Meanwhile, the squirty man squirted more stuff up the drain pipe and then down the pipe (see picture). This lead to thousands of wasps tumbling out of the bottom of the pipe and the drain is now heaving with them.
The man hung around chatting again, endlessly, and when he did finally leave, he was back within seconds because his car battery was flat - fortunately I have jump leads, so was soon able to get him on his way. It was a little bit like going back in time to the 1970s to talk to a Daily Mail reader (he actually gave me the business section!?): the country's going to the dogs; there's too much immigration and Australia's the best place to live.
