Fighting Mosquitoes With Genetically Modified Mosquitoes

They indiscriminately eat many insects...

And that's why they'd basically exterminate the other insects by just, you know, eating. Because the ammount of mosquitoes they'd have eaten is going to go towards the other insects-actually no, only flying insects. Bats can't start a flight from the ground, so ground hunting is out of the question until they evolve in a few thousand years. So what solution then? Kill bats?
