I have discovered a ground wasp(?) nest near my house. So I went to HD
and got a spray can, but when I read the instructions it seemed to deal
with nests in trees. The instructions say to "saturate the nest" but I
only have a small opening.
What's the best strategy?
At night, place a clear glass or plastic bowl over the opening, press it
slightly into the ground, and set a weight on top if it's plastic. As long
as the wasps can see daylight, they won't dig another exit, and within about
a week , will all starve and die.
You could start spraying as close as you dare to opening to knock down
and confuse wasps or yellow jackets in the air and continue to move down
and spray into opening. Dumping in a quart or more diluted Sevin would
be frosting on the cake.
Yellow Jackets are a common form of "ground wasp."
The "old school" solution was to pour a cup or two of gasoline in the hole
you found. The gasoline vapors displace the oxygen and the critters die,
die, die! Aftrward, the gas evaporates. It's likely illegal today.
Kerosene will not work because is doesn't generate the vapors and because it
contaminates the soil forever.

We put a window screen over the hole so they couldn't get out,
and then poured a cup of chlorine bleach and a cup of household
ammonia through the screen and into the hole. This makes
chlorine gas, which will kill you as well as the critters, so one
needs be careful, but it's heavier than air so it sits down there
right nice. It won't kill the plants the way regular unleaded
Don\'t worry about people stealing an idea. If it\'s original, you will
have to ram it down their throats.
The best solution is to leave them alone. If that won't work (they are
in a high-traffic area) use an insecticide dust. Something not *too*
fast acting (sevin is good, so is methoxychlor.) Wait until dusk and
throw a nice-sized pinch down the hole. They will get it on their feet
and contaminate the whole hive in just a day or two.
And then go rent a pump to empty out the basement, around my place at least.
That pink powder, poofed into the hole after dusk 2-3 days in a row, has
always worked for me. I always keep a few cans of the squirtgun spray
around too, for immediate revenge and gratification after they
mass-sting me. Seems to happen about once a year when mowing- this year
they flew up the sleeve of my shirt, and stung me from inside. Awful
hard to brush away under a shirt.
Always, within a week, something (skunk?) digs up the dead nest to
salvage the honey.
I had two nests this year. One in the ground, the other in an
exterior wall. I read about diy options but decided to opt for the
pro. Pro came out and took out the ground nest easily and permanently
in one visit. Never saw another yellow jacket from that nest. The
wall nest took a few applications of dust, but eventually he got it
Total cost: $90. Huge bargain.
