Bat and Bird Droppings Questions Answered in Charlestown

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.

What is histoplasmosis?

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.

Do barns and old buildings need special handling?

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.

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.

Can pigeon droppings damage a roof or building?

Yes. Droppings are acidic and can stain and wear down paint, metal and roofing over time. They also clog gutters and drains and create slip hazards on walkways. Cleanup and deterrents work best together.

Is it safe to stay home during guano cleanup?

For work in a sealed attic, many people stay in the home while crews work with containment. For heavy contamination or open spaces, it may be better to stay away. The team will say what is best for your situation.
