- Disinfection of wood framing, joists and hard surfaces with EPA-registered products

What First Hill Property Owners Ask About Guano and Histoplasmosis
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 should I do first if I find guano?
Do not sweep, blow or vacuum it. Keep people and pets away and leave it undisturbed until you know the size of the job. Call First Hill Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.
Do I need to replace attic insulation after guano?
Usually, if droppings or urine have soaked into it. Soiled insulation holds contamination and odor and cannot be reliably cleaned. After removal, new insulation is installed as a separate job.
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.
