1. Safety first

The crew checks for weak flooring, tight access and other hazards, then sets up lighting, protective gear and containment.

2. Collect the droppings

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

3. Remove and disinfect

Guano and soiled materials are taken out, and framing, floors and hard surfaces are cleaned and treated.

The owner receives a summary of the work for buyers, inspectors or insurers, and the area is cleared for use.

Guano Cleanup Frequently Asked Questions in Darien, WI

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.

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.

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.

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.

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.

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.

Worried about histoplasmosis from guano in Darien, WI?

Do not sweep or blow. A cleanup team can plan the safe way to remove them.
