How important do you think they are? I hate mosquitoes but I think they are critical. Wasps on the otherhand don't seem to be a big part of the food chain but make life hell for most large animals.
To be clear, I don't think wiping out any nuisance bug is good as the consequences typically accumulate down the food chain but some I suspect may have far less impact.
Afaik, their most important role is pest control because they eat tons of other insects.
They are also very important pollinators. IIrc, third most important after flies and wild bees(not honey bees).
I hate them too, but they are a critical part of our ecosystem.
