Bats play an essential role in our ecosystem by controlling insect populations. But when they infest your home, their droppings—known as bat guano—can pose serious health risks. Whether you’ve noticed bat poop on your porch or you’re dealing with a full-blown infestation in your attic or walls, understanding the dangers of bat guano is crucial for protecting your health, home, and family.
What Does Bat Poop (Guano) Look Like?
Before you can fully address the problem, you need to identify bat feces correctly. Bat droppings are small, dark, and often found in clusters. They can resemble rodent droppings but have a couple key of distinctions: bat guano tends to crumble easily when touched and may have shiny insect parts within.

Bacteria & Parasites
Guano can harbor harmful bacteria, and it also attracts mites, fleas, and bat bugs (a close relative of the bed bug) that feed on the droppings. Once a colony is removed without proper exclusion work, these parasites don't just disappear. They go looking for a new host, which often means the people living in the house.
Structural Damage
Guano and bat urine are corrosive. Over time, they can stain drywall and ceilings, break down insulation, and weaken the wood they sit on. A long-established colony can leave behind inches of buildup, adding weight and stress to the structure below it.
Air Quality & Odor
As guano builds up, it produces a strong, ammonia-like smell that can spread through attic insulation and ductwork, affecting air quality throughout the home.
Histoplasmosis
Histoplasmosis is caused by inhaling spores that become airborne when guano is disturbed, such as during cleanup.
What is Histoplasmosis, the “Bat Dung Disease?”
Histoplasmosis is a respiratory disease caused by the Histoplasma fungus, which thrives in bat guano. When disturbed, the spores can become airborne and lead to symptoms such as:
- Coughing
- Chest pain
- Fever
- Fatigue
- Shortness of breath
For individuals with weakened immune systems, histoplasmosis can become severe and even life-threatening. This is why bat infestations in enclosed spaces like attics and walls should be addressed by a professional wildlife control company immediately.
How to Deal With Bat Guano
If you discover bat droppings on your porch or inside your home, don't attempt to clean them up yourself.
1. Avoid disturbing the droppings. Stay away from the affected area and keep pets and children away as well.
2. Don't sweep, vacuum, or spray the area. Any of these can send spores airborne and spread contamination to other parts of the home.
3. Contact wildlife control professionals. If you suspect bats in your attic, walls, or other enclosed areas, Varment Guard can remove bats, clean up the guano, and disinfect the space.

Preventing a Bat Infestation
The best way to avoid dealing with bat guano is to stop bats from getting in your home in the first place. Here are a few steps to bat-proof your home:
- Seal Entry Points: Close gaps and cracks in your roof, siding, and attic to prevent bats from getting in.
- Install Bat Exclusion Devices: These allow bats to exit but prevent them from re-entering.
- Maintain Your Property: Regularly inspect your home for signs of a bat infestation, such as droppings, squeaking noises, or stains near entry points.
- Contact a Professional Wildlife Company: Bat entry points can be difficult to identify, and exclusion devices need to be installed correctly to work as intended. Varment Guard can inspect your property, seal it properly, and make sure bats are kept out.
Make Sure the Guano is Gone-O
While bats are beneficial creatures, their presence in or around your home can lead to significant health risks due to their droppings. Handling and preventing bat infestations is essential for maintaining a quality living environment. If you suspect a bat problem, don’t take any chances.
