Mission District 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.

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.
The animals come out first. Wildlife professionals handle exclusion, and rules about bats can vary by species, season and place. Cleanup follows once the space is no longer in use by animals.
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.
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.
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.
