Serra Mesa is on the drier side, with about 11 inches of rain a year, so old guano dries out fast and turns to fine dust that must be wetted before removal. Homes in San Diego range in age. Whatever the build year, insulation soiled by guano is usually removed and framing is cleaned and disinfected.
The work often covers:
- Sorting, cleaning and sanitizing of stored items and belongings that can be saved
- Sealing and bagging of contaminated waste for proper disposal
- Disinfection of wood framing, joists and hard surfaces with EPA-registered products
- Cleanup of pigeon and bird droppings on roofs, ledges, balconies and rooftops

What Serra Mesa Property Owners Ask About Guano and Histoplasmosis
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.
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.
Will the smell go away after cleanup?
Often yes, once the guano and soaked materials are removed and the area is treated. Deep stains in wood or drywall may need extra treatment, and the crew can say what to expect.
Can pigeon droppings damage a roof or building?
Yes. Droppings are acidic and can stain and wear down paint, metal and roofing over time. They also clog gutters and drains and create slip hazards on walkways. Cleanup and deterrents work best together.
How do I know if I have bats in my attic?
Common signs are dark droppings that crumble, stains on walls near gaps, a strong ammonia smell and squeaking or scratching at dusk and dawn. Droppings often collect in piles below entry points. A wildlife professional can confirm it.
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.
