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

Bat and Bird Droppings Questions Answered in Presidio Terrace
How much does guano removal cost?
It depends on the size of the area, the depth of the deposit, how much insulation must come out and how hard the space is to reach. A small ledge costs less than a full attic. The team sets the price after seeing the space.
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 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.
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.
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.
How do I get rid of the guano smell?
The odor comes from droppings and urine soaked into wood and insulation, so the fix is removing the source and treating surfaces. Air fresheners only cover it. Deep stains in wood may need extra treatment.
