Idk man, I've lived in a tiny remote village of only a couple hundred people with no water, electricity, plumbing or roads and mosquitos would go insanely hard during the summer. It was the village my mother and grandmother grew up in and I had the privilege to experience it for a couple years. It sucked.

I've seen those nat geo docs in Africa as well of remote villages where they trap mosquitos yearly during the swarm and make parties out of them to eat.

Small sample size but I don't think urbanizing is helping them explode in numbers. It is killing their predators though, you're right but it's also killing them.
