Bats are the only flying mammal and are quiet common in all of America. Because they eat their weight in flying insects and mosquitos every night, effectively limiting populations, they are extremely important to the environment and agriculture. In fact, they save American farmers up to 50 billions dollars every year, including 700 million dollars for Ohio’s farmers. While bats do carry rabies, it is not as common as most people think, and so they pose little threat to humans. However, bats can become a problem when they choose to roost in areas that are inhabited by people. Bats can be found in trees, under rock and woodpiles, roof eaves, attics and garages.
