Most housing in Waukesha County is occupied, with a vacancy rate of about 4%, but attics, chimneys and outbuildings can still go unchecked for years. Summers in Summit are milder, with July highs around 82 degrees, but guano in closed attics still dries and turns to fine dust over time.

A typical bird & bat guano cleanup job includes:

HEPA-filtered vacuuming and air cleaning to capture fine dust after removal
Cleanup of pigeon and bird droppings on roofs, ledges, balconies and rooftops
Cleaning of stained ceilings, walls and floors below an affected attic
Documentation of the work for buyers, inspectors, landlords and insurers
Sorting, cleaning and sanitizing of stored items and belongings that can be saved

Guano Cleanup Frequently Asked Questions in Summit, WI

What is histoplasmosis?

Histoplasmosis is a lung infection linked to a fungus that can grow in soil and droppings from birds and bats. People are exposed by breathing in spores. Many exposed people have no symptoms, and anyone who feels unwell after being around guano should tell a doctor.

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 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.

Can guano get into ductwork or vents?

Yes, if birds or bats roost near vents or intakes, droppings and dust can enter air paths. Cleanup may include treating vent openings and nearby surfaces.

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.

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.
