Bacteria Growth

Upon noticing bat poop upstairs, it’s easy to wonder: “Is bat dung in your attic dangerous?” The answer is yes. We’d be lying if we said it didn’t come with risks. But again, it can be removed with proper techniques and clean-up practices to leave your home free of bacteria. 

Leaving bat droppings to build up in the home is a health risk. An accumulation of droppings enables bacteria to grow. When the powdery guano breaks down, it releases airborne pathogens. As the pile enlarges, it could affect the insulation and attic structure. Droppings over time work their way into the structure, leaving a lasting smell that’s hard to remove. Bat dung in your attic is dangerous, but this problem has a realistic solution.


Histoplasmosis is the most common disease associated with bat guano. This airborne respiratory disease affects the lungs, infecting people when they inhale spores released from the guano. Fresh droppings often carry this disease.

While bats are also carriers of rabies, this fatal disease can only be contracted through direct contact with the animal, rather than by droppings left behind. Histoplasmosis is a higher risk factor as it’s easier to come into contact with. It’s important that homeowners don’t allow bat guano to build up in the home.

Who’s at Risk

Bat dung in your attic is dangerous—for some more than others. Occupation, age, and physical health are a few factors that impact who’s more likely to be affected by droppings. Chimney cleaners, construction workers, gardeners, roofers, and cave explorers have the highest risk of contact, as they work in areas where bats are commonly found.

Those with weaker immune systems, such as the very young and old, also face a higher chance of contracting a disease. A compromised immune system doesn’t perform at the same level to protect you from illness, meaning extra precautions are necessary around areas where bat droppings are found.


Homeowners can reduce the spread of guano and prevent diseases by bat proofing their homes. The best time to handle bat prevention is during the fall and winter seasons. Babies are able to fly by this time, and you’re less likely to trap animals inside.

Examine holes around the home’s exterior that could be potential entry points. It doesn’t take much for bats to squeeze their way inside. Use window screens, chimney caps, and other wire coverings as necessary to close any gaping cracks.


If you don’t think bat dung in your attic is dangerous, think again. Cleaning up the mess left behind by these critters should be the first priority. You can do it yourself with the right protective equipment, but this can be hazardous to your health. And for guaranteed sanitization, it’s best to enlist the help of wildlife removal experts. These specialists have the necessary tools, equipment, and action plan to not only evict the bats but also remove droppings and sterilize the space.

Bat removal services guarantee your home is guano-free. Whether bat poop is stuck in insulation or on wooden beams, wildlife removal experts will remove all pieces of insulation and scrape off remaining poop until it’s completely gone. Keep your family safe by cleaning up bat dung in the attic with the help of the experts.
