What Marshall Park Property Owners Ask About Guano and Histoplasmosis
Who pays for guano cleanup in a rental?
It depends on the lease and local law. Tenants should tell the landlord or manager right away. A landlord, an attorney or a tenant rights group can say who is responsible.
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.
Can you get sick from bat droppings?
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.
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.
How do I get rid of the guano smell?
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.
Can I clean a small amount of guano myself?
Sometimes. For a small spot, wear gloves, eye protection and a mask, wet the droppings lightly and wipe them up. Do not sweep or blow them dry. Thick, old or large deposits and attics are better left to a team.
