What Windsor Property Owners Ask About Guano and Histoplasmosis

How do I know if I have bats in my attic?

Common signs are dark droppings that crumble, stains on walls near gaps, a strong ammonia smell and squeaking or scratching at dusk and dawn. Droppings often collect in piles below entry points. A wildlife professional can confirm it.

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 Windsor Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.

Is it safe to stay home during guano cleanup?

For work in a sealed attic, many people stay in the home while crews work with containment. For heavy contamination or open spaces, it may be better to stay away. The team will say what is best for your situation.

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.

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.

Do I need to replace attic insulation after guano?

Usually, if droppings or urine have soaked into it. Soiled insulation holds contamination and odor and cannot be reliably cleaned. After removal, new insulation is installed as a separate job.
