How Guano Cleanup Works in Half Moon Bay, CA

1. Walk through the space

A cleanup technician maps the droppings, stains and damaged insulation in attics, lofts or on rooftops.

2. Hold the dust down

Moisture and containment keep spores and particles from becoming airborne during removal.

3. Wet, scrape and clear

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

4. Sanitize and deodorize

Remaining surfaces are disinfected, and the ammonia-like odor is treated at its source.

What Half Moon Bay Property Owners Ask About Guano and Histoplasmosis

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.

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.

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.

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.

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.

Does guano cleanup stop bats or birds from coming back?

No. Cleanup removes the mess but does not block entry points. A wildlife professional can seal gaps and use deterrents. Removing droppings and odor does help, since scent can draw animals back.
