About 23% of housing in Green Lake County is vacant, and empty buildings, barns and lofts give bats and birds quiet places to roost undisturbed. Summers in Berlin are milder, with July highs around 81 degrees, but guano in closed attics still dries and turns to fine dust over time.

A typical bird & bat guano cleanup job includes:

Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
Commercial guano cleanup on warehouses, storefronts, loading docks and parking structures
Containment and wet removal of bat guano from attics, wall voids and rafters
Cleaning of stained ceilings, walls and floors below an affected attic
Removal and disposal of insulation soaked with guano, urine and nesting debris

The Bat and Bird Droppings Removal Process in Berlin

1. Walk through the space

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

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. Disinfect and inspect

Wood, drywall and hard surfaces are cleaned and disinfected, odor is treated, and the crew checks the finished space.

Common Questions About Guano Removal in Berlin, WI

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.

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.

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.

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.

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.

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 Berlin Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.
