Histoplasmosis-Aware Guano Removal in Winthrop and Sibley County
Guano cleanup is the safe removal of bird and bat droppings from attics, barns, chimneys, roofs and ledges, along with soiled insulation, then disinfection of the affected area. Dust control is built into every step.
Guano is a respiratory risk, so your Winthrop property gets containment, wet methods and protective gear, then disinfecting and inspection before the space is handed back to you. For Sibley County owners, call Winthrop Biohazard Cleanup Help.
About 79% of homes in Winthrop were built before 1980, and older attics, vents and rooflines often have gaps where bats and birds can enter. Summers in Winthrop are milder, with July highs around 82 degrees, but guano in closed attics still dries and turns to fine dust over time.
The work often covers:
- Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
- Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
- Cleaning of stained ceilings, walls and floors below an affected attic
- Cleanup of pigeon and bird droppings on roofs, ledges, balconies and rooftops
- Odor removal and deodorizing of ammonia-like smells left by droppings
How Guano Cleanup Works in Winthrop, MN
2. Hold the dust down

3. Remove and disinfect
Guano and soiled materials are taken out, and framing, floors and hard surfaces are cleaned and treated.
4. Document and hand back
The owner receives a summary of the work for buyers, inspectors or insurers, and the area is cleared for use.

What Winthrop Property Owners Ask About Guano and Histoplasmosis
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.
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.
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.
Does guano damage insulation?
Yes. Insulation soaks up droppings, urine and odor and rarely comes back clean, so soiled insulation is usually removed and replaced. A team can tell you how far the damage goes after seeing the attic.
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.
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.
