Like an airplane in an old war movie, he kept making strafing runs over me, and it seemed with each pass he got lower and lower. He seemed to be pretty big, with a wingspan of about a foot. I closed the doors and made a strategic advance in a rearward direction. Bat Facts Bats are the only flying mammal. Bats use the echoes from their high-pitched squeaks to navigate and find prey.
Bats typically eat half their own weight of insects each day.
A bat can eat 600 mosquitoes in an hour. Recouping back in the hall, I thought about the situation. I knew that bats were not only generally harmless to people, but also beneficial in eating mosquitoes and other insects. After a few minutes I calmed down. Then I realized that I had just closed the bat in the room with the nicest woodwork in the house, and I definitely didn't want bat guano all over it.
