[Shop-talk] Eradicating yellowjackets in a stone wall?

[Neil Sherry]

I had a load of wasps arriving to set up home, accessing via a gap in 
brickwork. I used the vac for about 40 minutes to suck them up before 
they entered the crack, as well as nabbing any that came back out (was a 
bit like ghost busting). I had the vac in wet mode (so no filter or bag) 
with some water in the bottom - reasoning that they would eventually 
drop and drown - especially with the odd shake and swish. When they had 
stopped arriving I caulked up the crack and then listened for buzzing 
from the vac - there was none. When I plucked up courage to look inside, 
it looks like they had all succumbed to the sharp corner where the hose 
enters the machine - judging by the spatters there!
