Only about 19% of homes in Harrison were built before 1980, but newer roofs, vents and soffits can still give bats and birds a way in. Most housing in Calumet County is occupied, with a vacancy rate of about 5%, but attics, chimneys and outbuildings can still go unchecked for years.

What Happens During an Attic Guano Cleanup in Harrison

1. Walk through the space

A cleanup technician maps the droppings, stains and damaged insulation in attics, lofts or on rooftops.

2. Collect the droppings

Guano is collected without sweeping or blowing, and bagged on site so it never crosses clean rooms.

3. Wash and disinfect the structure

Joists, rafters, ledges and walls are washed and disinfected, and stained areas are 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.

Common Questions About Guano Removal in Harrison, WI

Is it safe to stay home during guano cleanup?

For work in a sealed attic, many people stay in the home while crews work with containment. For heavy contamination or open spaces, it may be better to stay away. The team will say what is best for your situation.

Is bird poop a biohazard?

Large amounts of bird droppings are treated as a contamination hazard because they can hold germs and fungal spores. A small spot outdoors is a simple wash. Thick buildup in a closed space needs protective gear and wet methods.

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.

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.

How do I get rid of the guano smell?

The odor comes from droppings and urine soaked into wood and insulation, so the fix is removing the source and treating surfaces. Air fresheners only cover it. Deep stains in wood may need extra treatment.
