<p>Well mosquitoes are one of the most dangerous insects in the world and if they're all exterminated they won't be missed. Here's a list of things that could happen if they were exterminated;</p><p>1. Malaria/yellow fever/Zika virus death rates will reduce: Without a means to spread these diseases, then there's no way they can survive for long in this world. They'd eventually become extinct just like mosquitoes would.</p><p>2. The ecosystem will be fine: Mosquitoes serve as food for a lot of birds, but the truth is that all those birds have alternatives and do t solely depend on Mosquitoes for their nourishment.</p><p>Over all, if mosquitoes were completely eradicated, it would probably do more good than harm for humanity as millions of lives would have been saved and ay least 3 deadly deceases will be eradicated alongside it.</p>
