Wasps: To Let Them Be or Eradicate
I noticed I have a wasp nest in a birdhouse next to my shed. It is in a corner of my garden, not too bothering, and so far they were peaceful (maybe only because it's new and there isn't too many of them yet).
I know they are predators and can eat pest insect, I would love to see them eating aphids and similar stuff. But I am also afraid they could eat too much of beneficial insect, like ladybugs, or maybe even attack or scare pollinators and bees.
Do you think their overall impact is beneficial or harmful? Should I try to eradicate them or should I keep them as a part of a "balanced ecosystem"?
