ᐅ Between the brick facade and the roof: Hornets are looking to settle in

Good day!

Last autumn, hornets began to settle in a gap just above the last row of bricks, practically right at the eave line. However, winter intervened, so nothing was done at that time. It is not certain that the insects will try again this year, but insect experts have advised me that it would be a good idea to seal this area to prevent new habitation. It is located directly above the front door, which poses too high a risk.

How would you suggest sealing this gap? Of course, I could prepare and nail a strip for each section, but I believe that the vertical joints between the bricks might still allow insects to get in. I assume a weatherstripping tape or foam seal should be applied to the strips before installation.

Or should it rather be sealed with a filler? If yes, with what material? I am wondering if there was a reason why we did not seal it completely back then. Maybe some airflow is intended. Perhaps I will look for a brown, mesh-like plastic fabric that I can staple to the wood at the top and let it run down behind the cladding. But I’m not sure if that will be sufficient...

Thank you for any helpful tips.

Matthias

So, which perforated material would you use? What you refer to as "joint mesh" is meant for butt joints, so about 1cm (0.4 inches) wide and the height of a brick. I need something around 60cm (24 inches) wide that can be attached across the top somehow.

Just search Google for "aluminum ventilation strip." It should be available by the meter. I’m not sure how to install it properly according to technical regulations. I would probably screw it firmly in place if there is something to screw it onto.

I will report here on how I eventually solved this. First of all, thanks to everyone!

Try using gentle and less labor-intensive methods:
- Hang a fake wasp nest under the roof
- They also dislike the scent of lemon

Last summer, we had problems with wasps that had made themselves comfortable behind our timber frame. I sealed the entry gaps with duct tape, which worked really well.

We have a similar problem here, and so far, nothing has provided a lasting solution. But I like the idea of using tape and will definitely try it out. Thanks! 🙂
