How to get rid of Hornets?

They don't like Fluid Film...

Nor brake cleaner. That's plan B when I run out of wasp spray at work.

If you haven't sprayed a nest there are venom collection companies around that will come and harvest the nest for free. Around here they usually respond in a couple of days. They get in there with a vacume cleaner and a bee suit and take the brood with them.
That being said I have found that the vacume with a long wand works pretty well, prop the wand so that the end is near the opening in the nest and let it eat for an hour or so. That will pretty much get all of the adults.
The venom guys put a 1/2" band of white tape around the end of the wand, makes them attack it.
If you use a shop vac with a filter bag some may survive getting sucked up, take the bag out a let them wirle around in the tank, they don't do so well .....

I know that it's gas, and gas is well, GAS, but...​

Well, maybe not such a good idea in this scenario.

One problem I have is that the bottom of their nest where the entrance hole is,is only about an inch above the floor of the cabinet and in the far back corner. To spray something in the hole I would need a long spray tube with a 90 degree, short upturn at the end of it.

I was wondering if I could get a powerful firecracker (the illegal kind) and throw it under the hole and damage the nest. I don't know how strong the nests are as I never saw one before.

At night, take a big hypo with 1 or 2 oz gas. Hold your breath. Insert needle in the top of the nest and inject. Leave. Go as far away as you can before you breathe. There are sentries. They can follow a CO2 trail.

The nest will die. Only the sentries will survive and theyll leave.

I just wanted the fireworks to blow a hole in the nest or blow it apart so I could get the spray inside it. Maybe at night I could hit it with a shovel to try to break it and run away. Then come back and spray after they settle back down.

I have some big plastic syringes but the last time I put gasoline in one, it melted the plunger and made it stick to the sides so it wouldn't squirt out.

Two years ago we had a couple nests of yellow jackets, and of course they each had to be right next to an entrance. I tried spraying raid type insecticides. That lasted a little while, but of course didn't get the queen or whatever else was going on inside the nest. In desperation, I looked around and found a large plastic syringe and some 1/4 plastic tubing. Filled it with some diesel, jabbed the tubing into the nest hole, and gave it a few cc shot. Hmm, did that ever confuse them. They had no interest in me, but instead on how are they going to get around whatever just pooped on their pillow. Those inside came out, and the incoming foragers flew around dumbfounded refusing to go in. I stood by 10ft away, and they had no interest in attacking anything or anybody. By day 2 the nests were empty.

Yeah, you only get one brief use from the rubber plunger unless you disassemble and clean and silicone grease it quick; even then a problem. I have saved all mine, and on several been able to substitute an oring. More chemical resistant AND replaceable.

If it's somewhere you don't mind a temporary mess, Dawn dish soap and water. The soap coats them and they can't breath. It has always worked for me regardless of how I applied. Poured down holes, used a spray tank, even my pressure washer for farther away nests. I have even sprayed up the ridges on metal roof. Always at night, and with an escape route in case things go south...

Chlorinated brake cleaner will kill them instantly in my experience. If they are flying and you spray them they will drop out of the air. So get a can, soak the nest, close the door to the shed and come back the next day.
