Identification

Both little brown and big brown bats have light brown fur with dark brown wings, ears and face. The difference in identification is the size. The little brown bats body is 6-10 cm long with a wingspan of 22-27 cm and the big brown bats body is 10-13 cm long with a wingspan of 28-33 cm. So the big brown bat is considerably bigger that the little brown bat. Bats are nocturnal and roost during the day in hollow trees, behind loose tree bark , in rock crevices and caves. If there are no natural sites for them to roost they will find old buildings, barns, attics, eaves and window shutters to spend their days.

What do bats like to eat

Bats are insectivorous and will eat a variety of night flying insects such as moths, beetles, wasps, black flies, and mosquitoes.  Bats are very beneficial to the environment as they eat their body weight in insects every night. They do a good job of keeping the insect population down..

Dangers of bats in your homes

Bats can cause a very pungent, musty odor from their urine and guano. If there is a large quantity of bats in your attic the excrement will eventually work its way down to your ceilings and discolour them making for a very unsightly show for your house guests. Usually your attics are very dry in the summer and this makes for very dusty conditions when cleaning up after an attic full of roosting bats.  They carry many diseases in their guano and one of the worst is Histoplasmosis.  It is a fungus that sometimes accumulates in their droppings. This can affect your eyes and lungs and in a serious case you could lose the eye or lung due to infection. Bats also carry the rabies virus so you should be careful when coming into contact with them. If the weather heats up the bats may be forced down your walls to find cooler air, they may find a way into your home because of this and you will find bats flying around your house. If in any way you suspect a bat was flying around in your home at night you should go to the doctor to get your rabies shots.. They could have come in contact without you realizing it and you don’t want to take that chance.
