Step by Step: Safe Guano Removal in Lancaster, WI

1. Keep everyone away

Family members, tenants, staff and pets stay out while the crew plans the work and gets into protective equipment.

2. Collect the droppings

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

3. Remove what cannot be cleaned

Soiled insulation, stained cardboard and nesting debris go into sealed bags, and hard surfaces are scrubbed.

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 Lancaster Property Owners Ask About Guano and Histoplasmosis

Who pays for guano cleanup in a rental?

It depends on the lease and local law. Tenants should tell the landlord or manager right away. A landlord, an attorney or a tenant rights group can say who is responsible.

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.

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.

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 you clean pigeon droppings safely?

Wet the droppings lightly, scrape them into a bag, then wash and disinfect the surface. Wear gloves, eye protection and a mask. Large roost areas, rooftops and enclosed spaces are best left to a team.

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.
