As a homeowner, discovering bat guano in your attic can be alarming—and for good reason. Bat droppings not only indicate a bat infestation but also pose serious health and structural risks. If you’re wondering what to do about bats in the attic or how to clean up guano safely, this guide is for you.
What is Bat Guano and Why Is It in My Attic?
Bat guano is the feces of bats, and it usually accumulates in attics where bats roost. It looks like small, dark pellets that may resemble rodent droppings, but it’s often found in piles beneath rafters, beams, or insulation. If you live in a quiet neighborhood or near trees, your attic might be an ideal shelter for bats.
Why Homeowners Should Be Concerned
Bat droppings in the attic aren’t just unsightly—they can lead to:
• Health hazards like histoplasmosis, a lung infection caused by fungal spores in guano
• Strong odors from accumulated bat waste
• Staining and damage to insulation and wooden structures
• Increased risk of bat-human contact, potentially exposing your household to rabies
Top Signs You Have a Bat Infestation
If you’re a homeowner, look for these common signs of bats in your attic:
• Piles of droppings near walls, vents, or insulation
• Scratching or fluttering sounds, especially at dusk or dawn
• Dark stains or greasy marks around attic entry points
• Unusual smells, especially a strong ammonia scent
• Sightings of bats flying from your roofline at sunset
What To Do if You Find Bat Guano in Your Attic
1. Do not touch or disturb the guano – Disturbing it can release airborne spores.
2. Call a licensed bat removal expert – Professionals will conduct a safe and legal bat exclusion.
3. Seal entry points after removal – Use mesh screens or caulk to prevent bats from returning.
4. Hire an attic cleanup service – Cleaning and sanitizing your attic ensures your family’s safety and prevents future issues.
Why You Shouldn’t DIY Bat Removal
Most states protect bats due to their role in the ecosystem, so bat removal from attics must follow specific laws. Attempting to remove bats or clean up guano yourself can:
• Violate local wildlife regulations
• Expose you to dangerous pathogens
• Lead to recurring infestations if not handled properly
How to Prevent Bats from Returning
• Inspect and seal attic entry points, such as vents, soffits, and chimneys
• Install bat houses away from your home to give bats a safer alternative
• Schedule regular attic inspections to catch issues early
