What does Bat Poop Look Like and How to Remove them

What does Bat Poop Look Like?

Because bats defecate while roosting on the roof, their droppings tend to be piled or collected in groups.

The droppings are typically black, soft, and quick to fall apart.

Sometimes you will see the droppings have a bit of sparkle. This color comes from undigested wings of the insects that the bats ate.

Individually they look like long thin pellets with blunt edges.

In general, bat droppings are about ¼ to ½ inches long and about ½ to 1 inch thick. 

But their size of bat poop varies depending on the species.

For instance, the little brown bats’ poop is about the size of an uncooked rice grain. The big brown bats’ dropping is slightly larger.

Bat dropping vs. Mouse Droppings

Mouse and bat droppings are often confused with each other and not without good reason.

Both droppings are dark or black in color and are usually found in similar places, such as in the attic or sheds.

That said, mouse droppings are different from bat droppings in many ways.

Mouse droppings, for instance, are usually scattered, while bat droppings typically come in piles.

Bat droppings also tend to be soft and crumbly when dry, while mouse droppings get very hard. 

Finally, bat droppings tend to be sparkly, while mouse droppings are not.

The crumbly texture and sparkle on bat poop come from undigested wings of the insects they eat.

While you may find some parts of insects in mouse droppings, they’re not going to be as prominent as those found in bat droppings. 

As such, mouse droppings turn hard when dry.

If you find yourself sweeping your porch or dropping, you’ll likely have bats living in your home.

If you have bats, you may also see some bats dropping on the sides of your home. That’s because bats tend to defecate on their way in and out of their harborage. 

You can also find piles of bat droppings below where the bats roost or hang in the attic. 

Are Bat Droppings Dangerous?

Yes. Bat droppings, called Guano, can be potentially harmful to human beings.

Old bat droppings can produce a fungus that can cause lung disease, known as Histoplasmosis when inhaled.

Histoplasmosis is a fungal infection that thrives in nitrogen-rich, humid, dark environments. 

The severity of the infection will vary depending on how much spores you inhaled and your overall health.

Histoplasmosis can stay in your lungs for an extended period. You can also get reinfection if you are exposed to it a second time. 

Bat droppings can also have parasites and other pathogens that can be harmful to touch.

For instance, bat poop can contain roundworms. Roundworms can become fatal when ingested or inhaled. 

Bat poops can also cause structural damage by decaying the wood in your home.

Finally, bat poop can encourage household pests such as roaches and termites, to live in your home.

As such, removing any build-up of bat guano is vital.
