Cleaning Up After Bats and Birds in Northridge, Milwaukee, WI
Bat guano removal is the careful collection of bat droppings, usually from attics and wall voids, using wet methods and containment. It protects people from dust that can carry fungal spores.
When bats or birds leave droppings on your property in Northridge, you get a crew that wets down and contains the material before removal. The team bags it, disinfects the area and checks the finished work. For Milwaukee County jobs, call Northridge Biohazard Cleanup Help.
Many homes in Milwaukee, about 84%, were built before 1980. Older insulation and wood framing soak up droppings and hold the smell. Summers in Northridge are milder, with July highs around 83 degrees, but guano in closed attics still dries and turns to fine dust over time.
Bird & Bat Guano Cleanup in Northridge usually includes:
- Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
- Cleaning of stained ceilings, walls and floors below an affected attic
- Odor removal and deodorizing of ammonia-like smells left by droppings
- Disinfection of wood framing, joists and hard surfaces with EPA-registered products
- Sealing and bagging of contaminated waste for proper disposal
What Happens During an Attic Guano Cleanup in Northridge
2. Suppress the dust
Technicians put on respirators and suits, then lightly wet the guano to keep fine particles from rising.
3. Take out contaminated material
Guano, matted insulation and nesting debris are packed out, and salvageable items are set aside for cleaning.
4. Sanitize and deodorize

What Northridge Property Owners Ask About Guano and Histoplasmosis
Will insurance pay for guano cleanup?
Sometimes, but not always. Many homeowners policies exclude damage from animals that builds up over time, and wording differs. Call your insurer before work starts, take photos and keep receipts.
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.
Is guano dangerous?
It can be. Dry guano releases fine dust, and some bird and bat droppings can carry a fungus linked to histoplasmosis, a lung infection. Many people never get sick, but older, heavy deposits carry more risk. Avoid stirring it up.
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.
What if droppings are on a roof or high ledge?
Roof and high ledge work needs fall protection and care around other people. Crews can remove and wash droppings there, and a property manager or owner can set up access.
Who removes bat guano from an attic?
A guano removal service or cleanup team usually does this work. It involves containment, protective gear, careful removal and disinfecting. Wildlife professionals handle the animals themselves.
