Yes, mainly from breathing in dust from dry droppings. Risk is higher with old, heavy buildup in enclosed spaces. People with asthma, lung conditions or weak immune systems need extra care and should stay out of the area.
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.
Wet the droppings lightly, scrape them into a bag, then wash and disinfect the surface. Wear gloves, eye protection and a mask. Large roost areas, rooftops and enclosed spaces are best left to a team.
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.
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.

Do not sweep or blow. A cleanup team can plan the safe way to remove them.
