Bat droppings cleanup includes more than the visible pile. Urine, staining and odor can soak into wood, drywall and insulation, which is why surrounding materials are checked and often removed.

About 66% of homes in Watertown were built before 1980, and older attics, vents and rooflines often have gaps where bats and birds can enter. Summers in Watertown are milder, with July highs around 81 degrees, but guano in closed attics still dries and turns to fine dust over time.
The work often covers:
- Disinfection of wood framing, joists and hard surfaces with EPA-registered products
- Commercial guano cleanup on warehouses, storefronts, loading docks and parking structures
- Containment and wet removal of bat guano from attics, wall voids and rafters

What Watertown Property Owners Ask About Guano and Histoplasmosis
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 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.
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.
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.
Does guano damage insulation?
Yes. Insulation soaks up droppings, urine and odor and rarely comes back clean, so soiled insulation is usually removed and replaced. A team can tell you how far the damage goes after seeing the attic.
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.
