East Williston gets about 45 inches of rain a year, and damp air keeps guano and soaked insulation wet, which strengthens odors and encourages mold on wood.

Bat and Bird Droppings Questions Answered in East Williston
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.
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.
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.
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.
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.
What rules apply to guano cleanup in New York?
Worker safety follows OSHA rules for hazardous dust, and waste disposal is handled according to local requirements. Rules about moving or excluding bats and other wildlife can vary by species and season, so check with a wildlife professional first.
