- Containment and wet removal of bat guano from attics, wall voids and rafters

Common Questions About Guano Removal in Denny Triangle, Seattle, WA
Does guano damage insulation?
Yes. Insulation soaks up droppings, urine and odor and rarely comes back clean, so soiled insulation is usually removed and replaced. A team can tell you how far the damage goes after seeing the attic.
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.
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.
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.
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.
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.
