Good luck with your soaking tonight , please update with the results .

All that will result in is a swarm of pissed off wasps... you best be ready to boogy if you shoot it and they can fly fairly fast.

I’ve done this more than once.

Get an electric bug zapper

Put is near. Closer is best.

Let it do its thing. It should really jump for a while.

After the occupants are 80-90% gone, hit it with a hose / shovel.

Done.

Hair spray and a lighter...

I had a huge hornets nest like that on my house. It sprayed it several times from about 10 feet away over several days. Each time it killed some until eventually all were gone. You should do it after dark when they are on the nest to do the most damage....and in the daytime, they will chase you down as there will be many out flying around that will come back to you violating the next. Hornets boil out of a big nest by the hundreds or even thousands...so have a plan and make part of that plan to stay away for the rest of the day. Even at light, if you spray the nest, hornets will follow your flashlight to try to sting you.

Are you guys using something like Spectracide Commercial Wasp & Hornet Killer? They don't come out the hole....nope...from 20' away :).

Lots of experience here....

Beer and Urine
 

I say drink a case of beer, get up close and whiz into that entry port circled in red. :)

Non toxic approach...what about that expanding foam stuff, fill that turkey with it, then set it on fire the next morning.

My choice, fire, hair spray and lighter would work great.

I have used serval brands (Spectacide and Hot Shot among others) that are good for 18-20 feet on the hornets here...and after an entire can, 4 or 5 hundred come out. About 100-150 fall and die and the rest chase my butt across the field. Wasps drop on the spot...but not hornets.

This is what they looked like when I sprayed mine:

I think I will pass on the urine stream or Great Stuff approach . Also not going to do the shotgun blast . So down to wasp spray or 🔥

I've got the smaller version and must say that burning the weeds growing through the walkway pavers is about a million times easier than trying to pull them out.

it will knock the nest down and it will rot away

you did not copy the part where I said use a stand-off weapon, which is what a shotgun is (for hornets)


of course, the best thing is to nuke it from space

that'll work -- if he has a long electric cord; it looks pretty far from an outlet

Soak with diesel from above - light from below.

A little anti-climatic. Shined the flashlight on the nest and soaked the opening with Raid Max Foaming Wasp & Hornet spray. Knocked a couple hornets off that were late back to the nest and continued to empty the can. Completely soaked the opening and foamed the nest. Tomorrow will tell if I need to treat this again. I do not know how I had not seen this earlier as it is larger than a football in size.

I've shot small nests with hornet/wasp spray and some always beat it out of there. And they pretty much know the location of the attacker so you better relocate quickly.

No advice on eradication. I let wasps live in peace as long as they aren't near a door. They eat insects. With the current SoCal daytime mosquito problem we need all the help we can get.

What a waste of a perfectly good tri-five Chevrolet.

There is only one true solution here: cold steel katana.
Please record a video for the rest of us.

Plus a monkey roll.

Not a 'Tri-Five' Chevy... technically...

It's a 55 or 56 only, not enough definition to say which.

The 57 had a totally different dash.

Bi-Five???? :)

Tri five is a reference to '55='56='57.

For the nest...the wasp sprays work. Once you get a kill, burn the paper nest.
