Bat and Bird Droppings Questions Answered in Sunnyside
How do you clean pigeon droppings safely?
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.
What if droppings are on a roof or high ledge?
Roof and high ledge work needs fall protection and care around other people. Crews can remove and wash droppings there, and a property manager or owner can set up access.
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.
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.
Why shouldn't guano be swept or blown?
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.
Should I remove the bats first or clean the guano first?
The animals come out first. Wildlife professionals handle exclusion, and rules about bats can vary by species, season and place. Cleanup follows once the space is no longer in use by animals.
