About 12% of housing in Suffolk County is vacant, and empty buildings, barns and lofts give bats and birds quiet places to roost undisturbed. With roughly 48 inches of annual rainfall in Cold Spring Harbor, roof leaks and humid attics are common, and moisture makes droppings heavier and harder to remove.
The work often covers:
- HEPA-filtered vacuuming and air cleaning to capture fine dust after removal
- Cleanup of pigeon and bird droppings on roofs, ledges, balconies and rooftops
- Disinfection of wood framing, joists and hard surfaces with EPA-registered products
- Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
- Sealing and bagging of contaminated waste for proper disposal
How Guano Cleanup Works in Cold Spring Harbor, NY
2. Suppress the dust
Technicians put on respirators and suits, then lightly wet the guano to keep fine particles from rising.
3. Take out contaminated material
Guano, matted insulation and nesting debris are packed out, and salvageable items are set aside for cleaning.
4. Sanitize and deodorize
Remaining surfaces are disinfected, and the ammonia-like odor is treated at its source.

What Cold Spring Harbor Property Owners Ask About Guano and Histoplasmosis
What rules apply to guano cleanup in New York?
Worker safety follows OSHA rules for hazardous dust, and waste disposal is handled according to local requirements. Rules about moving or excluding bats and other wildlife can vary by species and season, so check with a wildlife professional first.
Will the smell go away after cleanup?
Often yes, once the guano and soaked materials are removed and the area is treated. Deep stains in wood or drywall may need extra treatment, and the crew can say what to expect.
Is guano dangerous?
It can be. Dry guano releases fine dust, and some bird and bat droppings can carry a fungus linked to histoplasmosis, a lung infection. Many people never get sick, but older, heavy deposits carry more risk. Avoid stirring it up.
Who pays for guano cleanup in a rental?
It depends on the lease and local law. Tenants should tell the landlord or manager right away. A landlord, an attorney or a tenant rights group can say who is responsible.
How do I get rid of the guano smell?
The odor comes from droppings and urine soaked into wood and insulation, so the fix is removing the source and treating surfaces. Air fresheners only cover it. Deep stains in wood may need extra treatment.
How do I know if I have bats in my attic?
Common signs are dark droppings that crumble, stains on walls near gaps, a strong ammonia smell and squeaking or scratching at dusk and dawn. Droppings often collect in piles below entry points. A wildlife professional can confirm it.
