Normally I would pour some gasoline down the hole but what about opening my propane gas torch up (flame off). Propane is heavier than air so the gas would sink into the nest. Prefer not to kill some grass with gasoline.
Only done this once. I shot some wasp killer into the hole, then immediately dumped a scoop of sand on top. Then I used the shovel to cut down into the ground. Seemed to do the trick. But it wasn't a large mature nest, just something that popped up in a few days time.
They crawl around in the grass after dark rather than remaining tucked in their cozy warren in the ground?
These little devils have a whole bag of tricks.
We had four or five inches of rain last weekend and the ground nest I've observed in the back yard that was a veritable yellow jacket fountain a couple of weeks ago appears to be inactive.
Do you think they might have drowned?
Get several cans of the wasp spray that turns to foam when sprayed. Hit the hole at night and then dig them up w a shovel while spraying the nest and stragglers. Nice to have more than one person to do this. Back in the early 90's when I was a park ranger we had to do this often in the campgrounds. Gotta dig up that nest to be sure they are gone. Did one the other day during dayligh hrs and one found its way to my arm and got me!
Some years ago I had a yellowjacket nest in a flower bed. I put a hose up next to it and let it run quite slowly. It washed the nest right out. I don`t know where the wasps went but at least they weren`t there any more.
Simple and cheap. And safe - you control the flow rate from 20 or 30 feet away.
The marina at Moraine State Park about 60 miles north of Pittsburgh PA had a bee nest in the ground. They pored gasoline down the hole and lit it. The bee hole joined a pipe that was installed to channel a small stream that the property had before it was developed. The gasoline got into that pipe, and the pipe ended at the lake shore right next to where a sailboat was docked. The flames shot out of the pipe like a giant blow torch aimed right at the side of the sail-boat docked there. That destroyed the sail-boat. The marina ended up buying the sail-boat owner a new boat.

So be careful if you use gasoline and light it.
There is no need to light the gas the fumes kill the bees nest as it evaporates.
Yellow jackets eats lots of tiny insects in the garden . I will only kill off the nests when they are in an area where they are a nuisance. Last year I killed off two huge nests this year none and I see lots of the yellow jackets hunting for insects.
