Merlin's Response on Bats and Mosquito Control
There is no doubt that bats are primary predators of the vast numbers of insects that fly at night, and some species consume large numbers of mosquitoes when they are available.

Many of these insects are destroyers of gardens and crops, while many others are simple nuisances to humans and our properties.
