Most housing in Marathon County is occupied, with a vacancy rate of about 5%, but attics, chimneys and outbuildings can still go unchecked for years. Summers in Maine are milder, with July highs around 80 degrees, but guano in closed attics still dries and turns to fine dust over time.

Removal and disposal of insulation soaked with guano, urine and nesting debris
Sorting, cleaning and sanitizing of stored items and belongings that can be saved
Containment and wet removal of bat guano from attics, wall voids and rafters
Odor removal and deodorizing of ammonia-like smells left by droppings

The Bat and Bird Droppings Removal Process in Maine

1. Safety first

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

2. Hold the dust down

Moisture and containment keep spores and particles from becoming airborne during removal.

3. Remove and bag

Guano, soiled insulation and nesting debris are removed by hand or with HEPA-filtered tools and sealed in heavy bags.

4. Document and hand back

The owner receives a summary of the work for buyers, inspectors or insurers, and the area is cleared for use.

Bat and Bird Droppings Questions Answered in Maine

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.

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.

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.

Why shouldn't guano be swept or blown?

Dry droppings turn to fine dust that floats in the air and can carry fungal spores. Sweeping or blowing sends that dust into the air where you breathe it. Wetting first keeps particles on the surface.

Will the smell go away after cleanup?

Often yes, once the guano and soaked materials are removed and the area is treated. Deep stains in wood or drywall may need extra treatment, and the crew can say what to expect.
