Hayes Valley is on the drier side, with about 21 inches of rain a year, so old guano dries out fast and turns to fine dust that must be wetted before removal. About 76% of homes in San Francisco were built before 1980, and older attics, vents and rooflines often have gaps where bats and birds can enter.
The work often covers:
- Sealing and bagging of contaminated waste for proper disposal
- Containment and wet removal of bat guano from attics, wall voids and rafters
- Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
- Odor removal and deodorizing of ammonia-like smells left by droppings
- Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
How Guano Cleanup Works in Hayes Valley, San Francisco, CA
2. Collect the droppings
Guano is collected without sweeping or blowing, and bagged on site so it never crosses clean rooms.
3. Wet, scrape and clear
Droppings are wetted, scraped and collected, and insulation that cannot be cleaned is cut out and bagged.
4. Disinfect and inspect
Wood, drywall and hard surfaces are cleaned and disinfected, odor is treated, and the crew checks the finished space.

Bat and Bird Droppings Questions Answered in Hayes Valley
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.
How much does guano removal cost?
It depends on the size of the area, the depth of the deposit, how much insulation must come out and how hard the space is to reach. A small ledge costs less than a full attic. The team sets the price after seeing the space.
Can guano get into ductwork or vents?
Yes, if birds or bats roost near vents or intakes, droppings and dust can enter air paths. Cleanup may include treating vent openings and nearby surfaces.
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.
What rules apply to guano cleanup in California?
Worker safety follows OSHA rules for hazardous dust, and waste disposal is handled according to local requirements. Rules about moving or excluding bats and other wildlife can vary by species and season, so check with a wildlife professional first.
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.
