That sounds really frightening, Brian. I'm glad I don't have to deal
with those. Are they really yellow jackets, or are the some form of
hornet? What you describe sounds more like what we refer to as a hornet
nest.

Thanks for your comments, Brian. Years ago, I did the
same as you
suggest. But, with today's concerns about ground water
contamination,
it is not a good idea. When he finished extracting the
insects, Pete
placed Sevin dust in the hole to kill off the stragglers.
He says the
nests only last for one season, and the queen dies when the
workers
leave. Any new concerns are associated with the future workers
and
queens that have already departed, who will winter beneath tree
bark and
establish new colonies next year.

As far as I know, yellow-jacket nests here are
perennial, and keep on growing.
The largest I ever saw was hanging from
a tree branch out in the open and was at least 7 feet long (hanging) and
2 1/2 + feet through at the fattest dimension.
Here we had one grow in
an upturned half wine barrel within about a year to the size of 1 1/2
soccer balls.
Given the situation we could not use petrol, but some
fairly savage insecticide.
4 months later after the insecticide dust had
all vanished, I had to re-treat due to resurgence.
Cheers,
Brian
