Do NOT pour gasoline into the ground. Do NOT use insecticide near a pond (fish
gills absorb any trace of poison in the water and the fish dies).

For an underground nest, spray whip cream in the entrance at night. I am not
kidding. Millions of years of evolution have not prepared yellow jackets for
whipped cream.

For a hanging nest, get a flashlight and a pole and knock it down to the ground
at night. It will be abandoned in a few days, unless it's huge. In that case
you can boot it away somewhere at night (wasps generally refuse to fly in low
light levels).

Solitary wasps like the monstrous looking cicada killers and pepsid wasps
(tarantula hawks) will not sting you unless you grab one.

Don't do that.
