What Alki Property Owners Ask About Guano and Histoplasmosis
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.
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 much does guano removal cost?
It depends on the size of the area, the depth of the deposit, how much insulation must come out and how hard the space is to reach. A small ledge costs less than a full attic. The team sets the price after seeing the space.
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.
Will the smell go away after cleanup?
Often yes, once the guano and soaked materials are removed and the area is treated. Deep stains in wood or drywall may need extra treatment, and the crew can say what to expect.
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.
