An attic guano cleanup removes droppings from joists, beams and insulation, and treats the structure afterward. Insulation soaked with guano is usually discarded because it holds odor and contamination.

Many homes in Milwaukee, about 84%, were built before 1980. Older insulation and wood framing soak up droppings and hold the smell. Summers in Washington Heights are milder, with July highs around 83 degrees, but guano in closed attics still dries and turns to fine dust over time.
The work often covers:
- Sorting, cleaning and sanitizing of stored items and belongings that can be saved
- Removal and disposal of insulation soaked with guano, urine and nesting debris
- Cleanup of pigeon and bird droppings on roofs, ledges, balconies and rooftops
- Commercial guano cleanup on warehouses, storefronts, loading docks and parking structures
- Documentation of the work for buyers, inspectors, landlords and insurers

Common Questions About Guano Removal in Washington Heights, Milwaukee, WI
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.
How much does guano removal cost?
It depends on the size of the area, the depth of the deposit, how much insulation must come out and how hard the space is to reach. A small ledge costs less than a full attic. The team sets the price after seeing the space.
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.
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.
Is it safe to stay home during guano cleanup?
For work in a sealed attic, many people stay in the home while crews work with containment. For heavy contamination or open spaces, it may be better to stay away. The team will say what is best for your situation.
