- HEPA-filtered vacuuming and air cleaning to capture fine dust after removal
- Sealing and bagging of contaminated waste for proper disposal

Common Questions About Guano Removal in Visitacion Valley, San Francisco, CA
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.
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.
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.
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 Visitacion Valley Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.
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.
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.
