Humans have already caused so many species to go extinct.

Yeah, this idea scares me.

I thought they just didn’t breed in my habitat last time I moved— turns out they can breed here but they’re quite tightly managed.

What about house flies? Can we kill those too?

Mosquitos feed on apex predators and feed the nearly bottom of the food chain. Imo they're up there with salmon in terms of nutrient transfer, absolutely would cause chaos at all levels if they were eliminated.
