Good point. Bees don´t do that, I think.
Anyway, I do have an effective approach to wiping wasp/hornet nests out. I
use a rose duster, used to apply insecticide dust to rose bushes, to apply
Ortho Sevin dust. The dust does not annoy the wasps or hornets, so one can
simply walk up to the nest ignoring insects coming and going, put the duster
nozzle to the entrance, and crank the blower handle for a while. This blows
Sevin dust into all the nooks and crannies. Then walk away. Two hours later,
all buzzing has ceased. And the former nest is still poisoned, and so cannot
be recolonized for some time.
Ortho no longer makes a plant duster, but

And Sevin
dust:<

Sevin dust used to be 50% active ingredient; don´t know why it was diluted,
but I´d suspect the EPA. For this application, probably 5% works just
fine.
