  • Cleaning of stained ceilings, walls and floors below an affected attic
  • Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup

How Guano Cleanup Works in Glen, Baltimore, MD

1. Safety first

The crew checks for weak flooring, tight access and other hazards, then sets up lighting, protective gear and containment.

2. Suppress the dust

Technicians put on respirators and suits, then lightly wet the guano to keep fine particles from rising.

3. Take out contaminated material

Guano, matted insulation and nesting debris are packed out, and salvageable items are set aside for cleaning.

4. Disinfect and inspect

Wood, drywall and hard surfaces are cleaned and disinfected, odor is treated, and the crew checks the finished space.

What Glen Property Owners Ask About Guano and Histoplasmosis

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.

Who pays for guano cleanup in a rental?

It depends on the lease and local law. Tenants should tell the landlord or manager right away. A landlord, an attorney or a tenant rights group can say who is responsible.

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.

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.

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.

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.
