What Exactly Are Bat Droppings?

So, what are we even talking about when we say "bat droppings"? Well, they're the waste material left behind by bats, and they go by a special name: guano. These little pieces of material are a very common indicator that bats are present, especially if you're wondering if a bat is calling your house its home.

Where You Might Find Bat Droppings

If you're wondering where you might stumble upon these little signs, well, it's often in places where bats might choose to roost.
