probably bad for the planet.
They predate on a whole range of other insects and as such are part of the health and balance of the prey populations. I keep bees and was initially a bit paranoid about wasps, but having observed wasps help one of my hives through a bout of Chronic Bee Paralysis Virus (by removing the most ill from the population before they could spread the disease further), I relaxed a lot on that subject.
Which doesn't mean I actually like the vicious bastards, ofc.
Also up for wasp annihilation, probably bad for the planet.
