ᐅ Repelling wasps – What works best? Thanks for your tips!

I agree with Meister keks on this. In my case, spiders and wasps have no chance because I treat everything twice a year with permethrin. I have two bumblebee nests, which I leave alone. But wasps can damage your wooden structures as they chew on them to collect material for building their nests.

And if someone watches you, there is a heavy fine!

We went ahead anyway as they damaged the styrofoam insulation inside the roller shutter box.

I would recommend having the nest removed by a pest control professional; they have the expertise, and you will be safe. It just costs a bit more.

This thread actually made me smile. Back then, we had quite a large wasp nest inside the roller shutter box, and the carpenter who was there to replace the balcony door thought he didn’t need anyone to remove the nest—he would do it himself... with a vacuum cleaner *facepalm*. When we asked him to stop, he just waved us off and went ahead. As soon as the vacuum touched the nest, the wasps became very aggressive, and the first sting hit him right in the throat.

In the end, a fire department specialist had to be called, who sprayed the entire living room with insecticide, making it inaccessible for 48 hours. If the nice gentleman had been called right away, he would have easily handled it by using a wire to kill or remove the queen, and the wasps would have left peacefully. That would have taken about two hours at most...

And the moral of the story... some people know how to do it, some don’t.

We once had a wasp nest in the garden, and a company came regularly to mow the lawn and trim the hedge. However, one of the workers did not see the nest and accidentally cut into it. He was seen running away quickly but was only stung 2-3 times on the arm. Since then, they always check the hedge for wasp nests.
