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.
A guano removal service or cleanup team usually does this work. It involves containment, protective gear, careful removal and disinfecting. Wildlife professionals handle the animals themselves.
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.
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.
Do not sweep or blow. A cleanup team can plan the safe way to remove them.
