Hello everyone,
this summer we discovered a wasp nest in the attic space above the house. Since they didn’t bother us on the terrace, we didn’t mind it.
Wasps are supposed to die off towards winter, so we planned to remove the nest ourselves in January...
Now it’s December, and for a few days the wasps have been inside the house. They are very aggressive and attack immediately.
Today we tried to investigate by opening the roof hatch (located in the bedroom) to see if we could spot the nest or any wasps. We didn’t see a single wasp, but there was a huge nest at least 1 meter (3 feet) in diameter. Unfortunately, the nest is about 7 meters (23 feet) away from the hatch, so the pictures are very unclear. We can’t get closer either, since our attic has a height of barely 40cm (16 inches).
We will have the nest removed now, but we’re worried the wasps will make themselves comfortable under the roof again next year, and especially that they might have been gnawing their way through the walls, since they have to be entering the house somehow. We already looked everywhere but didn’t find a hole in the walls.
Does anyone have experience with wasps nesting in prefabricated walls? How can we check to what extent they have spread inside the walls and possibly damaged insulation or other components? Are there any preventive measures for next year?
By the way, we have a 2013 Bien-Zenker prefabricated house with an air-source heat pump heating system. Is it possible that the wasps are coming from the ventilation ducts?
Thanks in advance...

Oh! Yes, removing this nest is definitely a job for a professional. After removal, I would also strongly recommend having the building structure, such as walls and insulation, inspected to ensure there are no leaks or holes where water could enter and cause even bigger problems...
In the past, you would have just carried it out.
Now the district office, a building inspector, and an expert in wasp nest removal have to be involved.
But you have to admit, the thing is quite impressive in size.
By the way, wasps never use a nest twice. If only dying remnants are left inside, the problem should resolve itself.
The queen should normally be gone by now and starting a new nest elsewhere earlier in the season.

Friends contacted the local building authority.
1. No issues regarding the report of unauthorized removal of a wasp nest.
2. The authority provided a protective suit – simple beekeeper gear was not sufficient – no rental fee charged.
3. Recommended the appropriate spray cans and left two free of charge.
4. If the nest had needed to be relocated, the state government would have handled it.
5. Damages were recorded by the local authority, but the homeowner had to cover the costs since it is not a protected species.
The authority arrived on the same day.
