But if one looks closely at the advantages of having them around, it only seems natural. Foremost is their ability to wage war on mosquitos and other flying insects. Speaking of bug zappers, the average mouse-eared bat is capable of gobbling up his or her own weight in bugs, or 3,000 mosquitos, every night. It must take great amounts of energy to stay airborne for a long period of time. Small bat boxes designed for approximately fifty bats can produce a scoop shovel full every week during peak time of the growing season.
Dead bugs can be to our advantage in more ways than one.
You might ask about rabies and other diseases that bats can carry. This is nonsignificant when we look at the actual cases involved. Bats rarely conflict with other animals and even a rabid bat hardly ever becomes offensive. Simply left alone, bats are more than glad to return the favor. Grounded bats do warrant suspicion though, and should be handled with precaution.
