Bird & Bat Droppings: Destructive—and Hazardous to Your Health

When “just clean it up” becomes a hazard

Everyday dust? DIY is fine. But large accumulations of bird or bat droppings (guano) are different. They’re acidic and corrosive—hard on roofing, ledges, masonry, metal, signage, and HVAC—and disturbing them can send fine particles into the air you breathe.

The primary health concern

Areas contaminated by bird or bat droppings can be associated with fungal and bacterial risks, including histoplasmosis (lung infection caused by Histoplasma capsulatum when contaminated dust becomes airborne). Infants, older adults, and people with weakened immune systems are more vulnerable. If you’ve had exposure and develop fever, cough, chest discomfort, or unusual fatigue, talk to your healthcare provider.

Bottom line: Small, isolated spots can be managed carefully; large accumulations should be handled by trained professionals with containment, HEPA filtration, and proper PPE.

Why DIY is risky for big messes

• Airborne dust: Dry sweeping or leaf-blowing can aerosolize contaminants.
• Hidden damage: Guano can be many inches thick and trap moisture; corrosion often extends below the surface.
• Cross-contamination: Open HVAC returns or doorways can spread debris to clean areas.
• Disposal rules: Large volumes may require specific handling and transport practices.

How our professionals remediate safely

ServiceMaster Restoration By Simons follows industry best practices with IICRC-trained teams:

1. Assessment & safety plan – Identify volume, locations (attics, ledges, signage, mechanical rooms), access, and risk factors.
2. Containment & protection – Isolate work zones; protect or shut down nearby HVAC.
3. Wet methods + HEPA – Suppress dust, remove material with HEPA vacuums/industrial systems sized for the load.
4. Targeted cleaning & disinfection – Clean substrates; apply appropriate methods for odor control and hygiene.
5. Secure packaging & disposal – Handle, label, and remove waste with care and in line with local requirements.
6. Source control – Recommend exclusion measures (screening, sealing, deterrents) to prevent re-contamination.

FAQ: Bird & Bat Droppings Cleanup

Can I clean small amounts myself?
For small, isolated spots: wear gloves, eye protection, and at least an N95; lightly mist (don’t dry sweep), lift material carefully, double-bag, and wash hands. For moderate to heavy accumulations, attics, or anywhere near HVAC, call professionals.

Why shouldn’t I dry sweep or blow droppings away?
Dry sweeping and blowers can aerosolize contaminated dust. Wet methods and HEPA filtration are the safe approach.

Do bird or bat droppings always make people sick?
No. Risk depends on amount, disturbance, ventilation, and individual health. Larger accumulations and enclosed spaces increase risk.

What does a professional cleanup include?
Assessment, containment, wet suppression, HEPA vacuuming, targeted cleaning/disinfection, odor control, safe packaging/disposal, and source control (exclusion).

Will insurance cover guano cleanup?
Coverage varies by policy and cause (e.g., sudden event vs. maintenance). We’ll document conditions and coordinate with your carrier when applicable.

How do you prevent it from coming back?
Seal entry points (soffits, gaps, louvers), install screens/one-way doors where appropriate, and address attractants (standing water, food sources, roosting ledges).

Is rabies a concern with bat droppings?
Rabies is not spread through droppings. It’s a bite/saliva exposure risk. Avoid direct contact with bats and consult public health guidance if exposure occurs.

How fast can you start?
We offer same-day assessments and 24/7 emergency response. Crews are dispatched from Chicago and Skokie HQ to cover the metro quickly.

Do you handle odor and staining?
Yes. We use professional odor control strategies and substrate-appropriate cleaning to address staining, corrosion, and residual odors.

What if the droppings are on signage or high ledges?
We handle elevated work (lifts, fall protection), perform safe removal, and clean surrounding surfaces to prevent slip hazards below.
