This is where we delve into questions of whether we can understand the impact of our actions. Mosquitoes actually underpin a great number of relationships in nature. Most people have largely cast aside the question of whether it is ethical because of how much harm mosquitoes cause to humans, but there remains that sticky question of what happens to the ecosystems when they are gone.

Also, before someone posts a link to "that" article, let me say in advance it was written by an intern based on interviews that (in my opinion) suggest exactly the opposite of what the writer concludes.

It would be very bad. Birds and small fish hugely depend on mosquitoes for their diets.

Ticks are another matter. While birds will eat them, no species that I know of depends on them for its diet. We probably can safely eradicate ticks.

Mosquitoes help pollinate blueberries. Without blueberries we have nothing to anti the oxidants.
