Only about 23% of homes in Holmen were built before 1980, but newer roofs, vents and soffits can still give bats and birds a way in. Most housing in La Crosse County is occupied, with a vacancy rate of about 5%, but attics, chimneys and outbuildings can still go unchecked for years.

The work often covers:

  • Containment and wet removal of bat guano from attics, wall voids and rafters
  • Sealing and bagging of contaminated waste for proper disposal
  • Sorting, cleaning and sanitizing of stored items and belongings that can be saved
  • Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
  • Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup

Step by Step: Safe Guano Removal in Holmen, WI

1. Safety first

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

2. Collect the droppings

Guano is collected without sweeping or blowing, and bagged on site so it never crosses clean rooms.

3. Remove what cannot be cleaned

Soiled insulation, stained cardboard and nesting debris go into sealed bags, and hard surfaces are scrubbed.

4. Sanitize and deodorize

Remaining surfaces are disinfected, and the ammonia-like odor is treated at its source.

Guano Cleanup Frequently Asked Questions in Holmen, WI

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.

Can I clean a small amount of guano myself?

Sometimes. For a small spot, wear gloves, eye protection and a mask, wet the droppings lightly and wipe them up. Do not sweep or blow them dry. Thick, old or large deposits and attics are better left to a team.

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.

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.

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.

What is histoplasmosis?

Histoplasmosis is a lung infection linked to a fungus that can grow in soil and droppings from birds and bats. People are exposed by breathing in spores. Many exposed people have no symptoms, and anyone who feels unwell after being around guano should tell a doctor.
