Histoplasmosis and Hot Dry Attics
Histoplasmosis is a disease caused by a fungus that resides in bat droppings and areas contaminated by bird excrement. The fungus usually grows in moist nutrient environments. So the question is does the fungus survive in bat guano in hot dry attics? Well according to Bartlett et al. (1982) the answer is simply, “Yes.” Attics, even hot dry attics, with active bat infestations can cause people exposed to the droppings/fungal spores to contract histoplasmosis.
