The team asks where droppings were found, how thick they are and whether bats or birds are still using the space.

2. Wet down thick deposits

Heavy or caked droppings are softened with a light mist so they can be lifted without raising dust.

3. Wet, scrape and clear

Droppings are wetted, scraped and collected, and insulation that cannot be cleaned is cut out and bagged.

Guano Cleanup Frequently Asked Questions in Madison South, Portland, OR

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 Oregon?

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.

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.

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.

Is guano dangerous?

It can be. Dry guano releases fine dust, and some bird and bat droppings can carry a fungus linked to histoplasmosis, a lung infection. Many people never get sick, but older, heavy deposits carry more risk. Avoid stirring it up.

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.

Soiled attic insulation in Madison South, Portland, OR?

Do not sweep or blow. A cleanup team can plan the safe way to remove them.
