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

Bat and Bird Droppings Questions Answered in Mercer Island

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 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.

Will the smell go away after cleanup?

Often yes, once the guano and soaked materials are removed and the area is treated. Deep stains in wood or drywall may need extra treatment, and the crew can say what to expect.

Do barns and old buildings need special handling?

Buildings with years of buildup can hold thick, dry, dusty guano that is easy to disturb. Crews ventilate, wet down and use respirators and containment to keep spores out of the air.

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.
