Yellow jackets

Thanks for all the replies, Mine is in A hay barn, so I cannot use fire. I have sprayed then with
several kinds of spray, kill lots of them, but not all of them. I am going to keep spraying them,
I am not going to move, they will have to go.
Thanks A lot.

Gasoline works wonders on'em

The homemade water traps look cheap to build, not sure if they will eliminate the problem or just reduce the numbers.

Diesel fuel works good too.

Another thing is they are still hatching.Replacement fighters!

Yellow Jackets built a nest in the ground just outside my well pump house.
I took the tractor and dumped a scoop of dirt over the entrance hole and left it there for several weeks.
With no way to get in or out of the nest I assume they all died.

Your plight is most likely almost over even if you do not kill all of them.
Yellow Jacket nest only last one summer; after which the new queens will fly away to start more colonies. The remaining ones in the nest die at the end of the season, and the nest is not reused.

In a hay barn, and probably in bails to boot? OUCH! You've got problems. I feel for you. Yellow Jackets are vicious. I had a stack of railroad ties that I use for fence posts. They'd been there a while and they built a nest or nests that spread from the ties into a huge nest underground with multiple holes for entrance. Those guys actually hollowed out one of the ties for the comb, HUGE comb about three feet long by the time I saw it. How big underground? I never saw it, but it had to be as huge or huger. It was huge enough that a set of duals on a dualie sank down into the ground when I drove back and forth over it. Not buried, but sank down. I got them though. Before I got them, they came out stinging the hood on one of my Deeres after I bailed and ran like heck. They don't like something about running diesels. Them things chased me at least 50 feet as I ran. And here's the thing. I thought they were just in the ground. I didn't know they hollowed out one of the ties, the one right above, setting on their underground nest. While they were calm, I put a long chain around the opposite end of the tie, hooked it up to the drawbar of the Deere, wound 'er up, and took off with the tie flopping around behind me. I thought I was just uncovering the underground nest, didn't know that I was dragging a loaded comb behind me until I got off the tractor and went back to unchain the tie and when I rolled it over, out they came after me and the running diesel engine. Chased me at least 50 feet, probably 75 or 100 feet. They sure do get cranky. After it got dark I got them with that wasp spray that shoots like 25 feet. About 3 cans of it. Hollowed out the tie. That comb was huge. Long as my arm. The ground guys, I watched coming and going and located their holes. After dark, 25 foot shot spray at their holes to stop them, then flooded their holes with diesel fuel, lit it, let it burn out after about a half hour. Then drove the dualie back and forth to crush it all. Tires sank down a few inches.

Good luck. Got them in the hay barn and probably bails? YOUCH!

Ive had really good luck with an insecticide called Demonmax. I get it as a concentrate off of Ebay or Amazon whichever is cheaper. It runs about 25 bucks with free shipping. Makes about ten gallons of spray and has a pretty long lasting effect. It has a pamphlet explaining the uses and directions for mixing it.
