Only about 48% of homes in Williams Bay were built before 1980, but newer roofs, vents and soffits can still give bats and birds a way in. About 46% of housing in Williams Bay is vacant, and empty buildings, barns and lofts give bats and birds quiet places to roost undisturbed.

The work often covers:

  • Odor removal and deodorizing of ammonia-like smells left by droppings
  • Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
  • Cleanup of pigeon and bird droppings on roofs, ledges, balconies and rooftops
  • Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
  • Containment and wet removal of bat guano from attics, wall voids and rafters

How Guano Cleanup Works in Williams Bay, WI

1. Find every deposit

Crews check roost sites, rafters, ledges and insulation, since droppings build up where animals return again and again.

2. Suppress the dust

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

3. Remove what cannot be cleaned

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

4. Clean the air and surfaces

HEPA filtration clears the air, surfaces are disinfected, and the owner is walked through the result.

What Williams Bay Property Owners Ask About Guano and Histoplasmosis

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 rules apply to guano cleanup in Wisconsin?

Worker safety follows OSHA rules for hazardous dust, and waste disposal is handled according to local requirements. Rules about moving or excluding bats and other wildlife can vary by species and season, so check with a wildlife professional first.

Does guano cleanup stop bats or birds from coming back?

No. Cleanup removes the mess but does not block entry points. A wildlife professional can seal gaps and use deterrents. Removing droppings and odor does help, since scent can draw animals back.

How do I get rid of the guano smell?

The odor comes from droppings and urine soaked into wood and insulation, so the fix is removing the source and treating surfaces. Air fresheners only cover it. Deep stains in wood may need extra treatment.

What should I do first if I find guano?

Do not sweep, blow or vacuum it. Keep people and pets away and leave it undisturbed until you know the size of the job. Call Williams Bay Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.

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.
