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. Summers in Mission Dolores are milder, with July highs around 62 degrees, but guano in closed attics still dries and turns to fine dust over time.
A typical bird & bat guano cleanup job includes:
- Removal and disposal of insulation soaked with guano, urine and nesting debris
- Containment and wet removal of bat guano from attics, wall voids and rafters
- Odor removal and deodorizing of ammonia-like smells left by droppings
- Cleaning of stained ceilings, walls and floors below an affected attic
- Disinfection of wood framing, joists and hard surfaces with EPA-registered products
How Guano Cleanup Works in Mission Dolores, San Francisco, CA

4. Disinfect and inspect
Wood, drywall and hard surfaces are cleaned and disinfected, odor is treated, and the crew checks the finished space.

What Mission Dolores Property Owners Ask About Guano and Histoplasmosis
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.
Is bird poop a biohazard?
Large amounts of bird droppings are treated as a contamination hazard because they can hold germs and fungal spores. A small spot outdoors is a simple wash. Thick buildup in a closed space needs protective gear and wet methods.
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.
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 Mission Dolores Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.
What if droppings are on a roof or high ledge?
Roof and high ledge work needs fall protection and care around other people. Crews can remove and wash droppings there, and a property manager or owner can set up access.
What rules apply to guano cleanup in California?
Worker safety follows OSHA rules for hazardous dust, and waste disposal is handled according to local requirements. Rules about moving or excluding bats and other wildlife can vary by species and season, so check with a wildlife professional first.
