Bat Guano Cleanup and Attic Restoration
Bat guano is a documented biological hazard. We provide certified cleanup and attic restoration across Utah using EPA-registered disinfectants and OSHA-compliant protocols.
Why bat guano is dangerous
Bat droppings can carry Histoplasma capsulatum, a fungus that causes histoplasmosis when dry spores are disturbed and inhaled. The risk is not theoretical, and it scales with how long a colony has been roosting.
- Risk increases with accumulation. Old, dry guano releases far more spores than fresh droppings when disturbed.
- High-risk populations. Elderly residents, children, and immunocompromised individuals face the greatest risk of serious infection.
- Never disturb without PPE. N100 respirator, Tyvek coveralls, and gloves are the minimum required protection.
- Bat urine causes structural damage. Uric acid saturates wood, corrodes metal fasteners, and destroys insulation R-value.
- Ammonia odors penetrate living spaces. Without professional treatment, the odor can permeate through ceiling assemblies into rooms below.
When cleanup is needed
| Situation | Cleanup needed? |
|---|---|
| Single bat, no roosting evidence | Usually not. Spot inspection sufficient. |
| Small colony, first season | Recommended. Spot disinfection. |
| Colony active 2 to 3 seasons | Yes. Professional cleanup required. |
| Colony active 4+ years or 50+ bats | Yes. Full attic remediation. |
| Ammonia odor in living spaces | Yes. Immediately. |
| Brown ceiling or wall staining | Yes. Urine has saturated structure. |

Common questions
How much does bat guano cleanup cost in Utah?
Typically $500 to $4,500+ depending on attic size and contamination level. Every job starts with a free written estimate.
Can I clean bat guano myself?
Small, fresh amounts can be cleaned with proper PPE. Large or dry accumulations require professional HEPA equipment and EPA-registered disinfectants. Do not use a standard household vacuum. It will aerosolize and spread histoplasmosis spores throughout the home.
Does homeowners insurance cover bat guano cleanup?
Standard policies typically exclude pest and wildlife control, but resulting structural damage may be covered. Check your specific policy and ask the carrier directly.
