Guano Cleanup Frequently Asked Questions in Duvall, WA

How do I know if I have bats in my attic?

Common signs are dark droppings that crumble, stains on walls near gaps, a strong ammonia smell and squeaking or scratching at dusk and dawn. Droppings often collect in piles below entry points. A wildlife professional can confirm it.

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.

Does guano cleanup stop bats or birds from coming back?

No. Cleanup removes the mess but does not block entry points. A wildlife professional can seal gaps and use deterrents. Removing droppings and odor does help, since scent can draw animals back.

What should I do first if I find guano?

Do not sweep, blow or vacuum it. Keep people and pets away and leave it undisturbed until you know the size of the job. Call Duvall Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.

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.

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.
