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

Hey,

like our neighbors, we have a problem with wasps nesting under the parapet upstand, building their nests there.

This is quite annoying because, on one hand, a family member is allergic, and on the other hand, we are worried about structural damage.

I have nothing against wasps themselves, but I am concerned when I know that a sting can be very dangerous and that the building structure could be damaged. What can I do to get rid of them without immediately calling a wasp removal service or something similar? Is there anything that works? Water, for example?

I’m not looking to kill the insects, but to make it clear to them: please don’t nest here!

Does anyone have experience with this?

Rinsing them off daily with water?
Or just go for the heavy-duty solution from the hardware store.

I’ve tried both.
I gave up on option a1 after about two weeks of daily attempts and then bought the power spray from the hardware store.

What kind of nest is that? Is it hanging freely and spherical, or located in some kind of niche? If it’s hanging freely, these are not the annoying creatures that steal soda and cake, but insect-eaters that will probably leave you alone (they can still sting, but there tend to be fewer conflicts).

Removal also depends on the situation – on our balcony, we had a spherical (unfinished) nest with only the queen inside, which I simply brushed away with a broom and quickly went inside until she flew away. Let her build her nest elsewhere. However, I wouldn’t do this if the nest is already fully active.

It is inside recesses... as I said... it’s under the upstand, meaning beneath a metal sheet. You can’t see the nest from the outside, but you can see the insects building it. I don’t want to wait until it reaches the size of a tennis ball or soccer ball. We will try water first and, if necessary, will actually have to resort to the spray.

There are some fake nests that are supposed to work well. And citronella – I would spray it in the frequently used areas.

If I had this problem and it was outdoors, I would immediately use strong chemicals, and the issue would be resolved.
