Buildings with years of buildup can hold thick, dry, dusty guano that is easy to disturb. Crews ventilate, wet down and use respirators and containment to keep spores out of the air.
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.
Sometimes, but not always. Many homeowners policies exclude damage from animals that builds up over time, and wording differs. Call your insurer before work starts, take photos and keep receipts.
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.
Dry droppings turn to fine dust that floats in the air and can carry fungal spores. Sweeping or blowing sends that dust into the air where you breathe it. Wetting first keeps particles on the surface.
Histoplasmosis is a lung infection linked to a fungus that can grow in soil and droppings from birds and bats. People are exposed by breathing in spores. Many exposed people have no symptoms, and anyone who feels unwell after being around guano should tell a doctor.
