There are several studies that claim that mosquitos could be eliminated from the food chain without affecting their local ecosystems.

The problem is a lot of those studies sre 20+ years old, and there are far fewer insect species today than there were then. Mosquitos are more important as a food source than they used to be. Driving them extinct now would save human lives, but it might also cause ecological collapse.

That’s not to say we shouldn’t wipe them out if we can. But we need to be more cautious about how and where we kill all the bugs, because that might be the last of the bugs.
