[1] There's no such thing as a "specific wasp poison". Wasps are
insects and can be killed by insecticides. Insecticides vary from
disgustingly nasty organophosphate cholinesterase inhibitors
(basically nerve poisons) e.g. Malathion, to "nice" simple soapy
water.
[2] Chlorox (i.e. bleach) is just one brand of the domestic standard
5-6% solution of sodium hypochlorite. A bottle of it will kill off
the worms, bacteria, etc. as well as the wasps, and probably mess
up the grass nearby for a while. You could probably kill the wasps
by doing the same trick with a used Chlorox bottle filled with
soapy dishwater.
[3] A slowly running hose might be simpler. Just fill the nest cavity
with water and keep it full for a while.
[4] During the day a good fraction of the wasp population will be out
foraging - and will come home ! They will all be home when it gets
dark.
[5] What ever method you use, the probability of one of the entrance guards
"getting" you if you attack the nest is non-zero.
[6] Getting them to abandon the nest and go somewhere else is not as
simple as it sounds. (Beekeepers do sometimes use repellents, but
that just makes the bees pile up outside the hive.)
[7] [DOES NOT APPLY IF YOUNG CHILDREN ARE INVOLVED]
Why not live and let live ? Just stay away from immediate vicinity
of the nest and they won't bother you any more than they bother
people half a mile away. One of my favorite tricks when I see
people going "argh, wasps/bees !" and thrashing their arms around
during a picnic in a park is to walk over to the people, pour a
little pool of sugared soft drink into the palm of my hand and
wait. I soon gather a little circle of wasps/bees on my hand
happily lapping up the "nectar". It makes the point ..
A WASP/BEE FORAGING =/= A WASP/BEE ATTACKING.
However,
SQUASHING THE WASP/BEE == ATTACKING THE WASP/BEE

I think this thing must be kept in perspective. Granted that it would be
nicer not to have to use these toxic chemicals but the tradeoff might be
damaging a few square inches of the environment to prevent the death of
someone due to a wasp sting. "Environmentally sound" methods might be
to bring in a bulldozer and bury the whole mess 6 feet deep OR pour a
dewar of liquid nitrogen into the hole. :-)
We've never had any underground wasp nests. However, we have found an
environmentally safe way to get rid of the wasp nests hanging from the
underside of the house roof edges, so I thought I'd pass that along in case
anyone's interested. Perhaps this could be modified to get rid of underground
nests too. (Note: All disclaimers apply, since anything you do to aggravate
wasps could potentially cause them to attack you. However, my husband has done
this many times in the past couple of years without being stung.)
The most important thing is to wait until the wasps are dormant before doing
anything to annoy them. They are usually less active after dark; however, the
air temperature is also important. Try to wait for a fairly cool night (maybe
60 degrees F.). Now, turn on the garden hose; use a hose sprayer attachment
with a quick on/off switch built into it, and turn it on full force. Spray the
nest until it starts falling apart; then flip off the hose switch and run like
heck to the inside of the house. (Note: Obviously, make sure there isn't anyone
else standing around nearby before you do this.)
Now you can watch the activity from a safe haven (inside the house). You will
see the wasps buzzing around furiously for a while (probably the remainder of
the evening). Assuming you completely destroyed their nest, they will usually
go build a new nest somewhere else rather than staying in the area where they
were disturbed.
Good luck!

1) Regardless of which method you use to destroy a wasp nest you should ALWAYS
do it at night. During the day many wasps are foraging for food and will come
back to the nest before nightfall. If they find the nest filled in or
destroyed they will be VERY, VERY upset.
So, step 1 is to wait for nightfall.
2) Get a plastic garbage bag or sheet of poly that can cover a good area
around and over the nest. Also get a garden hose (attached to a water supply)
or a pail of water - 5 gallons or more.
3) Place the plastic over the nest. Warning, even though it's night and the
wasps are relatively inactive, there will be two or three guards at the nest
entrance. Therefore you want to cover the nest quickly and efficiently. Try
to anchor the plastic with sand or dirt around the edges.
4) Worm your garden hose through a hole in the plastic or between the plastic
and the ground into the nest entrance - push it in a few inches. If you're
not attached to a tap, then use a funnel and your pail of water.
5) Let the water into the nest a good rate. Try not to overflow the nest and
disturb your plastic, but make sure that the water pushes wasps down into the
nest. Keep adding water until the nest is full. Leave the sheet (and even the
hose) overnight and check in the morning.
6) Fill the nest again until you see no live wasps.
You may want to wear a beekeeper's veil or similar headgear just in case. Also,
as much as it may be undesirable, have a can of wasp killer pesticide handy.
Propoxur (Baygon) will kill wasps immediately if they come swarming from the
nest.
If you have to run (8>o) run for bushes if possible and make a lot of movement
of branches as you run into them. Wasps are very visually oriented and a lot
of moving branches in your path may fool some of the attackers.
(A small shrub does not constitute "bush" - a thicket or dense underbrush does
give you adequate protection - but keep running until you don't see any wasps!)
If you are trying to get rid of a nest that's in a tree or under an overhang,
a paper nest that's easily visible, wait for evening and with a ladder and
lots of guts, quickly surround the nest with a green garbage bag. Try to seal
the bag around the whole nest. You then cut the branch or pull the nest off
the overhang and get that bag into a barrel of water. I don't advise that
you do this without the use of a pesticide! You'd be better to stream the
spray into the nest entrance as you approach it and douse the interior as you
come right up to it. Then to the baggie trick.
Best of luck (8>).

Heck, when I was a kid in Oregon we looked for the hanging nests, and
threw big rocks at them to knock them off the tree. Then we rank like
hell. In my older, wiser, and slower days, I'd advise fire or chemical
weapons.

Great story, Tony!
There's a piece of companion advice that I've heard: "Never swat a
yellowjacket." Apparently, these wasps will release a cloud of "alarm
pheromones" if you attack/swat/squash them. This will enrage any other
wasps of the same species who smell the pheromone (nearby, or downwind)
and they will swarm in and attack.
Hence, if you kill one yellowjacket, you'll soon have to kill dozens.
Your chances of getting stung would be quite high, I'd think.

It sounds like a classic case of wasp, or yellow-jacket, infestation.
Both of these bugs look like lethal bombadiers with their abdomens
hanging down as they fly, unlike honey or bumble bees,w hich fly with
their bodys sort of straight out. Yellow jackets have a bright,
yellow and black "Don't mess with me" colour scheme, while generic `wasps'
often lack much coloration and are dark greenish.
These bugs are much more easily peeved than honey bees, and are much
nastier when they are P.O.'d. They often make their nests in the rafters
of houses, as well as in the walls. Call the Orkin man; don't mess with
them yourself.
I have used with great success, a small amount of petrol poured into the
nest late in the evening when all the wasps have gone beddy-byes. I believe
the petrol asphixiates (!spelling) the wasps, certainly there is never
any evidence of the nest surviving. A small amount means about an eggcup
full.
