I recall reading that mosquitos in GENERAL play a big part in the food web, but the mosquito species that bite us could go away without much ecological impact.

Of course it’d be an expensive undertaking without a huge benefit (there are other creatures that bite us and infest our homes). Not to mention the risk that we simply don’t know everything about how ecosystems work.
