Bat droppings cleanup includes more than the visible pile. Urine, staining and odor can soak into wood, drywall and insulation, which is why surrounding materials are checked and often removed.

What Grand Lake Property Owners Ask About Guano and Histoplasmosis
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.
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.
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.
Can I clean a small amount of guano myself?
Sometimes. For a small spot, wear gloves, eye protection and a mask, wet the droppings lightly and wipe them up. Do not sweep or blow them dry. Thick, old or large deposits and attics are better left to a team.
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.
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.
