Damn, not sure but it appears to be a hornet nest. Either way a PITA.
I recently had a colony of Africanized bees take up residence in between a scupper and new roof.
About 7-10k bees. I ended up purchasing a professional bee suit via Amazon for $97. I first used Stryker 54 contact kill followed by sure kill powder. I sourced these from a DIY pest control store.
A shop vac was used to suck out the angry bees after fogging them with Stryker 54.
The sure kill fine powder is used at the nest opening to ensure the bees track in the Poision
to the queen. Once this bitch is dead any bees that were out working find a new place.
The swarm of Africanized bees.

The Stryker 53 has a fold out straw for tight spraying.
Folded as shown will produce a fog. The Sur kill powder is fine like baby powder and used last for those returning bees who then track in the poision to the queen.

This is a thick 100% cotton bee suit with a zippered vail. I still wore a thick long sleeve sweat shirt and sweat pants because have an allergy to bee stings. It total it took 10 days to eradicate and take back our yard. In your case once activity ceases take that nest out and seal it in a garbage bag or burn it.
I had to pull boards from under the porch to ensure all dead bees were removed. I also didn’t give them a chance to build a hive because then the honey becomes a problem in itself when left behind a wall. These things are no joke.
I’ve responded to many bee attack that resulted in dead horses, dogs and people.
With the right PPE you can mitigate your problem. I think in total I had $160 with the suit and poison. I had an estimate of $400-800 to have a bee expert do the job with no guarantees in extracting all dead bees.
I did get hit once on my right eyelid during my initial assessment. Super aggressive bees as I was about 50 yards away. At one point during my initial attack, I could smell the venom as they swarmed and stung the vail.
I still recommend duck tape at the ankles and wrists and use heavy pull up boots and thick gloves.
Amazon offeres bee suits from $50-200. I went with a middle road price ($97) and was very pleased with the quality and fit. One size bigger to allow heavy clothes under the suit.
