Is your level of knowledge on this just "there are other things called mosquitos ergo it's not a problem," or do you have deeper affirmative knowledge that the animals that eat these mosquitos also eat those other mosquitos, and that those other mosquitos can increase their population to replace the lost food source?
That's called risk.
Pointing out risk is not "fearmongering" lmao
Pointing out risk is a kind of fearmongering when it's technically real but too small to be worth worrying about. Asteroid impact is a real risk too.
