How Guano Cleanup Works in Portage, WI

1. Find every deposit

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

2. Hold the dust down

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

3. Wash and disinfect the structure

Joists, rafters, ledges and walls are washed and disinfected, and stained areas are treated.

4. Final walkthrough

Odor and air are checked, and the owner is shown what was done and what remains for other trades.

Bat and Bird Droppings Questions Answered in Portage

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.

Who pays for guano cleanup in a rental?

It depends on the lease and local law. Tenants should tell the landlord or manager right away. A landlord, an attorney or a tenant rights group can say who is responsible.

Is guano dangerous?

It can be. Dry guano releases fine dust, and some bird and bat droppings can carry a fungus linked to histoplasmosis, a lung infection. Many people never get sick, but older, heavy deposits carry more risk. Avoid stirring it up.

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.

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.
