Forest Knolls 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:
- Sorting, cleaning and sanitizing of stored items and belongings that can be saved
- Removal of nests, feathers and carcasses left by birds or bats
- Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
- Sealing and bagging of contaminated waste for proper disposal
- Documentation of the work for buyers, inspectors, landlords and insurers

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

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

Common Questions About Guano Removal in Forest Knolls, San Francisco, CA
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.
Can I clean a small amount of guano myself?
Sometimes. For a small spot, wear gloves, eye protection and a mask, wet the droppings lightly and wipe them up. Do not sweep or blow them dry. Thick, old or large deposits and attics are better left to a team.
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.
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.
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.
What should I do first if I find guano?
Do not sweep, blow or vacuum it. Keep people and pets away and leave it undisturbed until you know the size of the job. Call Forest Knolls Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.
