Just want to mention that whenever a bat is in the house it should be killed and tested for rabies. You might want to call your doctor to see if he feels you should get vaccinated. Bats can land on you while you are sleeping and that is considered rabies exposure. They can bite you without you even knowing it. The same thing happened to my friend and the whole family had to get vaccinated. On the other hand my parents live behind a car dealership with the high lights on all night and always have bats in their attic. They have gotten in the house frequently over the years and they also just shoo them out.
