My girlfriend has been offered an insect hotel and we decided to hang it on our balcony (we live in an apartment close to the forest in Denmark). It has attracted wasps and they have started building a nest inside a cavity supposed to be used by butterflies (I can see it through the slit).
Right now it is not bothering because the wasps are few and very tame : they're not attracted by food, don't come inside and completely ignore anyone on the balcony. They just relentlessly fly in and out. The nest is small, roughly 6cm in diameter, and can't expand so much because the cavity is a cube about of about 10cm of edge length.
Should I get rid of it while it is still easy, or should I leave it alone ?
