Bird and Bat Guano Cleanup in Upper Fell's Point, MD

Although wildlife exclusion and cleanup are distinct jobs, their timing may be coordinated. Ask who will inspect the entry points and confirm that the animals are out. Repairs should block renewed access but not trap animals, with cleaning scheduled after all required exclusion work is done.

Before cleaning starts, have a wildlife specialist verify the bats have left and deal with access openings. Timing and exclusion methods can be affected by wildlife rules and the presence of young bats. Never close a known entry gap until you verify that doing so will not trap animals indoors.

Removing source-area droppings, nesting material and insulation soiled by urine should reduce the odor. Cleanable surfaces are then treated, and hidden joints or cavities are checked for residue left behind. Odors may come back unless water intrusion, a leaking roof or ongoing wildlife access is also fixed.

Moving a heavy, dry deposit can put fine residue and fungal spores into surrounding air. The amount of waste and site conditions shape the hazard, while some deposits do not result in illness. Avoid sweeping or using a household vacuum. People with health concerns should seek advice from a medical professional about possible exposure.

A single recent dropping on a hard surface is different from buildup across insulation or rafters. Professional cleanup is safer for waste that covers a broad area, creates dust, affects insulation, sits by vents or cannot be reached easily. Restrict access for both people and pets, and never use a dry broom as you determine the cleanup plan.

No, not always. The decision depends on where droppings and urine reached, how deeply they entered the insulation and whether clean sections can be separated. Material with widespread or deep contamination may need removal. Clean insulation outside the affected areas may remain when it can be protected during the work.
