What Marrowstone Property Owners Ask About Guano and Histoplasmosis

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.

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.

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 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 Marrowstone Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.

Can pigeon droppings damage a roof or building?

Yes. Droppings are acidic and can stain and wear down paint, metal and roofing over time. They also clog gutters and drains and create slip hazards on walkways. Cleanup and deterrents work best together.

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.
