Pigeon and Bird Droppings Cleanup in Seattle, WA

Bat guano removal is the careful collection of bat droppings, usually from attics and wall voids, using wet methods and containment. It protects people from dust that can carry fungal spores.

If you are a homeowner, landlord or property manager in Seattle, WA, you can get bat and bird guano removal. Crews work at any hour in attics, lofts, rooftops, chimneys, balconies and warehouses across King County. To start, call Seattle Biohazard Cleanup Help.

Summers in Seattle are milder, with July highs around 77 degrees, but guano in closed attics still dries and turns to fine dust over time. Many homes in Seattle, about 53%, were built before 1980. Older insulation and wood framing soak up droppings and hold the smell.

Bat and Bird Droppings Questions Answered in Seattle

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.

How do you clean pigeon droppings safely?

Wet the droppings lightly, scrape them into a bag, then wash and disinfect the surface. Wear gloves, eye protection and a mask. Large roost areas, rooftops and enclosed spaces are best left to a team.

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.

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.

Will insurance pay for guano cleanup?

Sometimes, but not always. Many homeowners policies exclude damage from animals that builds up over time, and wording differs. Call your insurer before work starts, take photos and keep receipts.

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.
