Cleaning Up After Bats and Birds in Orinda, CA

Guano cleanup is the safe removal of bird and bat droppings from attics, barns, chimneys, roofs and ledges, along with soiled insulation, then disinfection of the affected area. Dust control is built into every step.

Need droppings removed without spreading dust in Orinda or across Contra Costa County? You get cleanup technicians who use HEPA-filtered equipment and keep your family members, tenants and staff away from the work area. Call Orinda Biohazard Cleanup Help.

Summers in Orinda are milder, with July highs around 74 degrees, but guano in closed attics still dries and turns to fine dust over time. About 82% of homes in Orinda were built before 1980, and older attics, vents and rooflines often have gaps where bats and birds can enter.

A typical bird & bat guano cleanup job includes:

Sorting, cleaning and sanitizing of stored items and belongings that can be saved
Documentation of the work for buyers, inspectors, landlords and insurers
HEPA-filtered vacuuming and air cleaning to capture fine dust after removal
Cleaning of stained ceilings, walls and floors below an affected attic
Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup

What Happens During an Attic Guano Cleanup in Orinda

1. Find every deposit

Crews check roost sites, rafters, ledges and insulation, since droppings build up where animals return again and again.

2. Wet down thick deposits

Heavy or caked droppings are softened with a light mist so they can be lifted without raising dust.

3. Wet, scrape and clear

Droppings are wetted, scraped and collected, and insulation that cannot be cleaned is cut out and bagged.

4. Treat and verify

The space is disinfected, deodorized and inspected, and the crew explains what repairs or insulation work may follow.

What Orinda Property Owners Ask About Guano and Histoplasmosis

What is histoplasmosis?

Histoplasmosis is a lung infection linked to a fungus that can grow in soil and droppings from birds and bats. People are exposed by breathing in spores. Many exposed people have no symptoms, and anyone who feels unwell after being around guano should tell a doctor.

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.

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.

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.

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.
