Hello everyone,
this summer we discovered a wasp nest in the attic space above the house. Since they didnât bother us on the terrace, we didnât mind it.
Wasps are supposed to die off towards winter, so we planned to remove the nest ourselves in January...
Now itâs 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 didnât 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 canât get closer either, since our attic has a height of barely 40cm (16 inches).
We will have the nest removed now, but weâre 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 didnât 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...

Unfortunately, the distance from the roof hatch to the nest is about 7 meters (23 feet), which is why the pictures are so poor. We also canât get any closer because our attic has a clearance of just under 40 cm (16 inches). How does anyone come up with the ridiculous idea to design such a pointless cavity? And how is a firefighter supposed to crawl in there?

Oh, by the way, we have a Bien-Zenker prefabricated house from 2013 with an air-source heat pump system. Could it be that these creatures are coming from the ventilation ducts?

Could it be that the bugs are coming from the ventilation?There should be screens or grilles in place to prevent insects from entering. Also, there should be filters inside the unit. Or what do you think?
Winniefred5 Dec 2020 11:25If the wasps are aggressive, I would definitely call a professional. They can actually cause significant damage. We once stayed in a holiday home where they got under the roof from the outside and chewed their way through the wooden cladding, entering the living area through cracks. I was glad it wasnât our own problem. So, I would definitely want to find out where they were getting in and try to seal it. Also, check for any damage, as they can chew through insulation as well. The nest was quite large, so the colony inside was correspondingly big.
We have wasps in the greenhouse, almost every year in the same spot. We let them build there because they are peaceful field wasps. But if there were any damage to the house, I would take action.

Well, I think the room/area must be ventilated to prevent mold.
And whether you can manage that without letting pests in, I have my doubts. Exactly: you simply canât achieve that. Thatâs why people donât build an attic that isnât even properly crawlable in the first place. You use such spaces with open roof undersidesâfor example, as a suitcase shelf in the walk-in closet, a loft bed in the childrenâs rooms, or above the bathtub where you might install a double casement window for a view of the sky. Planners of poorly designed houses should be made to buy one themselves and live in it for a minimum period based on the severity of their mistake. ;-)
