These are the same mosquitos that pass lyme and other diseases. They’re all over the world where there are tropical climates. This is relevant because climate change is making more areas suitable for these insects to live and breed. As those areas expand, the human population is going to have to change infrastructure to compensate. Any surface where water can stand for a length of time is a breeding ground for mosquitos. Many parts of the world don’t have safeguards like screens over windows and such to prevent insects from entering homes.
