Evidence of Bats in the Attic
With so many damp caves to live in, why would a bat be seeking out your attic? Your attic is dry, dark, and hot; which is perfect for bats. Your attic is also free of all predators, which bats have quite a few of. They are extremely vulnerable while they are sleeping the day away, which makes them easy access for all sorts of predators.
Seeing a bat leave your home is the easiest way to determine that you are having a bat problem. You will often see them fly out of the roost around sunset, since they are nocturnal, this is when they are leaving the roost to hunt. This method will not only show you for sure that you’re dealing with bats, but will also give you a rough idea of approximately how many you are dealing with.
Identifying their droppings is another method of determining bat activity. Their droppings are called Guano, which has a distinctive appearance and odor. Bat guano can often be found in large piles in the roosting area, or on walls or entry points that the bats are using to gain access to the home.
You may also be able to hear soft noises that can help identify bats. While bats are notoriously silent creatures, they may make slight rustling sounds when disturbed - such as being frightened by a door slamming in the home. You may also hear the rustling near the time that they are leaving the roost.
