After sundown, bats fly around most regions of the world. Like most animals, they leave their droppings around for people to find.

Read on to learn what bat scat looks like, bat poop images, and whether or not the waste is safe for humans and pets.

What Does Bat Poop Look Like?

What does bat poop look like? Most of the time, bats poop close to their roost. If there is bat poop in a building, it is not unlikely that the bats are using a loft or the eaves as their roost. Before jumping to this conclusion, it’s crucial to know what to look for so you don’t mistake bat poop vs. mouse poop.

Bat droppings come in the shape of little footballs or a grain of rice, and they are round in the center with thinner ends. They shimmer in the right lighting and come in twos.

Bat Poop vs. Bird Poop: Difference Between Bat Poop and Bird Poop

Although both soar through the sky, birds and bats have very different droppings.

If you’re wondering who the poop on the windshield belongs to, here is how to tell the difference.

Bird poop has a greener hue than bat poop. Bat poop should be dark in color, but a healthy bird will have green, yellow, yellowish-brown, or white poop.

Bird poop also has a lot more liquid in it. So, when you come across bird poop, it will normally look like it splats onto the surface. Bat poop will stay solid when it falls.

If you find dark, football-shaped feces, it most likely belongs to a bat.


Bat scat is roughly half an inch long. To be more exact, they tend to be a little under 3mm wide with a length of 10mm. This size is common for small mammals, so size may not be the most effective way to identify bat poop.


Bat poop is dry and bumpy in texture but weak in structure. To test if it is a bat dropping, put on a rubber glove or use a paper towel. Pick up the dropping and apply a small amount of pressure.

If the poop easily crumbles under light pressure, it is probably bat waste.


Bat scat takes on an ovular shape with a cylinder-like shape toward the center. Its shape resembles a miniature football or a cooked grain of rice. Sometimes, the ends are pointy.


Bat poop is dark in color. It’s normally black or dark brown and shiny in certain lighting. The feces sparkles because of the chitin in their diet, which comes from insects’ exoskeletons.

Tips from Our Vets

Though it may seem weird to try to identify different animals’ feces, there are many cases where you may need to do exactly that.

Many home and property owners come across animal feces and are concerned about what animals may be lurking. Being able to identify the feces that wildlife and rodents leave behind will not only let you know what animals are in the area, but also can give clues as to how many of them are present.

At first, it can be distressing to find foreign looking animal feces in your home or on your property. Fears of aggressive or rabid animals, as well as the diseases they may carry are often the first worries.

Protecting your family and pets is of utmost importance. However, taking the time to correctly identify the feces is essential in assessing the threat or risk from the animals.

This research will also enable a home or property owner to devise an effective strategy for keeping any pest animals out of their homes, barns, or other areas where they are not welcome.

Scat Identification Techniques

  1. The first thing to do if you come across scat, or feces from animals, is to observe the location of the droppings. Notice where the feces are in relation to buildings, other structures, other animals, water, roads, and vegetation. Different animals will place their droppings in particular locations and this can be the first clue to identifying them.
  2. Next, observe the placement of the scat. Are the feces hidden or buried? Are they randomly dropped all over an area with seemingly little regard for placement, or are they tucked away in corners or neat piles? These factors can greatly narrow down the list of possible culprits.
  3. Note the size of the scat. If you are investigating feces found in your home or on your property, it is a good idea to obtain a ruler or tape measure that you can use to measure. Some animals’ feces may look identical to others from the same family, and size may be the only distinguishing feature. *REMEMEBR: animal feces can carry both diseases and parasites so they should never be handled without gloves.*
  4. What is the shape of the found fecal matter? Some shape characteristics to look for include if the feces are round, tapered at the ends, completely tubular, round pellets, twisted, or moist mounds.
  5. An additional clue to the species of animal leaving the scat is what is included in the feces. Berries, hair, seeds, and plant parts should all be looked for in the droppings. This information can be used to identify the animal that left it.
  6. Lastly, look around the area where you first identified the scat. In cases of feces from animals that have similar appearing feces to another species, it can be helpful to search for nearby footprints or tracks left by the animals. This can be used to confirm species.

Is Bat Poop Hazardous & Bad For Pets?

Keep pets as far from bat feces as possible. Bat poop often contains fungal spores called H. capsulatum, which can make your pet very sick. The dangers aren’t greater than exposure to bird droppings, but they shouldn’t be licking either.

Humans will not contract any illnesses from bat scat unless they are touching it, consuming it, or failing to clean it right away.
