San Jose is on the drier side, with about 16 inches of rain a year, so old guano dries out fast and turns to fine dust that must be wetted before removal. Most housing in San Jose is occupied, with a vacancy rate of about 5%, but attics, chimneys and outbuildings can still go unchecked for years.
A typical bird & bat guano cleanup job includes:
- Disinfection of wood framing, joists and hard surfaces with EPA-registered products
- Cleanup of pigeon and bird droppings on roofs, ledges, balconies and rooftops
- Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
- Commercial guano cleanup on warehouses, storefronts, loading docks and parking structures

What San Jose Property Owners Ask About Guano and Histoplasmosis
What is histoplasmosis?
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.
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.
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.
Should I remove the bats first or clean the guano first?
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.
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.
