My oh-so-dry daughter said 'Like a wasp you mean' and then we went
onto devices like a wasp gun that would first dispense a blob of jam
followed by half a dozen wasps fired backwards (that should also make
them suitably angry). ;-)

I read the vacuum cleaner bit out to her just now and she added that
said passing Chav could see what the cleaner ( full of wasps) could do
when set on blow .. like a wasp gatling gun .. or maybe (assuming the
cleaner was battery powered) find where he stops, gaffa tape his doors
up then blow the contents into the car, via the air intake. ;-)

I like your daughter!
