Well, we literally have skin in the game. Somewhere around a hundred billion humans have existed, and around half of those were killed by mosquitoes. Given they've eradicated one in every two humans since we became human, I wouldn't exactly say they're "beneath us," but we do have a legitimate beef against them.
One other quick point. To the poster who says we shouldn't keep pets because it isn't their natural habitat, they're domesticated by definition, so living alongside and with humans is their natural habitat. They might survive away from us, some individuals more than others, but domesticated animals are a very different thing than wild ones.
