[ WP ] We have eradicated mosquitos , just in time for summer . Turns out , they 've been protecting us from something .

Mosquitos are poison. They had to go, they did nothing to benefit anything. So scientists released a gas. It was specifically designed to kill Mosquitos only, essentially turning them on themselves. After it got approved, once a week, they flew the planes across the globe. 
 
 Everything seemed normal, until the planes stopped releasing the gasses. It was slow, the bats began to appear. They sat on power lines at night, staring, silent, unmoving. They began to increase in number. The government ordered for the planes to continue delivering the gas, and the bats went away. 
 
 They kept some alive in a lab. The news is showing promise.
