What Is Histoplasmosis?
Histoplasmosis is a fungal lung infection caused by inhaling spores from Histoplasma capsulatum — a fungus that grows in bat guano. According to the CDC, it is the most common respiratory fungal infection in the United States.
Troy MI and Southeast Michigan sit in the histoplasmosis endemic zone. Bat colonies are common in older Troy homes — particularly those built before 1980 — where deteriorating rooflines and fascia boards allow bat entry into attics.
Troy MI Exposure Risk Scenarios
Symptoms of Histoplasmosis
Symptoms appear 3 to 17 days after exposure. Mild cases are often mistaken for flu.
😷 Mild to Moderate Exposure
- →Fever (100–103°F)
- →Dry cough or chest tightness
- →Fatigue and body aches
- →Headache and chills
- →Loss of appetite
Resolves in 2–4 weeks in healthy adults
🚨 Severe / Compromised Immunity

- →Significant weight loss
- →Swollen lymph nodes & joint pain
- →Skin sores or lesions

Requires antifungal medication 3–12 months
Who Is Most at Risk?
Anyone can develop histoplasmosis from significant exposure. These groups face elevated risk of severe disease.
Adults Over 55
Immune response decreases with age — higher risk of severe or disseminated infection.
Infants & Young Children
Underdeveloped immune systems cannot contain fungal spread effectively.
HIV/AIDS Patients
Histoplasmosis is an AIDS-defining illness. Immunosuppression allows rapid systemic spread.
Transplant Recipients
Immunosuppressant medications reduce ability to fight fungal infection.
Chronic Lung Disease
COPD, emphysema — damaged lung tissue creates more area for fungal colonization.
Steroid / TNF Users
RA and Crohn’s medications suppress immune response — high risk of severe infection.

Histoplasmosis & Bat Guano in Troy MI
Can you get histoplasmosis from bats in Troy MI?
Yes. Histoplasma capsulatum grows in bat guano, and Troy MI bat colonies in older attics create ideal spore conditions. Disturbing dried guano without proper PPE can cause infection regardless of your health status.
What are the symptoms of histoplasmosis?
Symptoms appear 3–17 days after exposure: fever, fatigue, dry cough, chest pain, and body aches. Mild cases resolve in 2–4 weeks. Severe cases require antifungal medication and can last months.
How long does histoplasmosis last?
Mild histoplasmosis resolves in 2–4 weeks. Severe cases require itraconazole or amphotericin B for 3–12 months. See a doctor if symptoms persist more than one week after possible exposure.
Is bat guano cleanup safe to do yourself in Troy MI?
No. DIY bat guano cleanup without an N-100 respirator, full protective suit, and wet-spray disinfection spreads spores and causes infection. Professional remediation is required for any attic infestation.
Does homeowners insurance cover bat guano cleanup in Troy MI?
Most standard policies exclude pest damage. Some cover remediation if the infestation caused structural damage. We provide full documentation for insurance claims — call us before beginning any work.
