Bats are blind. Bats always get tangled in human hair. All bats bite and carry rabies and diseases. Not all bats bite and carry diseases. Bats seldom transmit disease to other animals or humans, but bats are wild animals and should not be disturbed, in case they are carrying certain diseases.
All bats drink blood.
The little brown bat is a harmless insect eater. When bats occupy a human dwelling, the smell, sight, and sounds from the colony are sometimes considered a nuisance. Bats do not gnaw wood, build nests, or cause damage to buildings. Histoplasmosis, a fungal respiratory disease associated with birds and other animals, may be found in the guano where bats roost. Infection can occur when the fungus is inhaled while collecting dry bat droppings.
