Also, Mosquito larvae grow in water and are a source of food for aquatic wildlife.

I seriously doubt that we understand every aquatic ecosystem well enough to know if eliminating mosquitos entirely would be harmful in the long run. And once we eliminate them, there's no going back.

No one is talking about eliminating all mosquitos (despite the headline).

There are over 3,000 species of mosquito. If there weren't any Aedes or Anopheles larvae in the water, other species would expand to fill the empty niche.
