Pigeon and Bird Droppings Cleanup in St. Francis, WI

Bat guano removal is the careful collection of bat droppings, usually from attics and wall voids, using wet methods and containment. It protects people from dust that can carry fungal spores.

Guano is a respiratory risk, so your St. Francis property gets containment, wet methods and protective gear, then disinfecting and inspection before the space is handed back to you. For Milwaukee County owners, call St. Francis Biohazard Cleanup Help.

Most housing in Milwaukee County is occupied, with a vacancy rate of about 8%, but attics, chimneys and outbuildings can still go unchecked for years. Housing age varies across St. Francis, but dry guano and old insulation behave the same in any attic and call for dust control and protective gear.

A typical bird & bat guano cleanup job includes:

  • Sealing and bagging of contaminated waste for proper disposal
  • Containment and wet removal of bat guano from attics, wall voids and rafters
  • Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
  • Cleaning of stained ceilings, walls and floors below an affected attic
  • Removal of nests, feathers and carcasses left by birds or bats

The Bat and Bird Droppings Removal Process in St. Francis

1. Walk through the space

A cleanup technician maps the droppings, stains and damaged insulation in attics, lofts or on rooftops.

2. Contain and suit up

Plastic barriers seal the work zone, and technicians put on respirators and disposable suits.

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. Sanitize and deodorize

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

Guano Cleanup Frequently Asked Questions in St. Francis, WI

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.

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.

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.

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.

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.
