What is Cladosporium?
The genus Cladosporium is a genus of mold. There are more than 40 Cladosporium species of fungus. Some species can grow indoors while others thrive outdoors, especially on decaying plant material. Either way, t frequently occurs in humid areas or moist places.
Appearance
Cladosporium appears in clusters of black, yellow, or green spots. The spots spread quickly when not cleaned away. This mold often forms where moisture is present.
How it spreads
Spores from the mold can be airborne, which is also how the mold spreads.
It can easily spread within the home, especially when the spores come into contact with dark, damp surfaces. This type of mold is more common in areas with humidity, moisture, and water damage. Poor ventilation and high humidity levels also contribute to the growth of this type of mold.
How to identify
Even though it’s a common species, it is almost impossible to identify Cladosporium visually. A person with mold in their home should consult with a mold-testing professional to identify the Cladosporium species correctly, so that it can be removed safely. It may also be possible to send mold samples to a laboratory for testing.
Where it grows
As with other types of mold, this mold commonly grows in humid or wet areas, like bathrooms. Other places that are typically susceptible to growth include attics, near kitchen sinks, behind the refrigerator, bathroom or kitchen cabinets, laundry rooms, and near window air conditioning units. Water damage can also lead to all mold growth.

Is Cladosporium a toxic mold?
The answer to this question is complex and depends on a variety of factors, including the species of Cladosporium and the individual’s sensitivity to it. It is not known to have any toxic effects on human health, but it can cause some allergy symptoms if the person around the mold is allergic. It has been reported to cause infections of the skin and toenails as well as sinuses and lungs.
Infants are especially sensitive to exposure to this type of mold (skin test studies have shown an allergic reaction in forty-two percent of children tested).

How do you prevent Cladosporium species mold?
Moisture is the number one cause of mold growth in homes. Bathrooms, kitchens and basements frequently harbor moisture that can cause mold to grow quickly. Prevent moisture from causing mold growth by taking some simple, preventative steps.
- Always be sure to clean up water spills right away.
- Repair all plumbing leaks as soon as they are noticed.
- Make sure rooms prone to high humidity, like your bathrooms and kitchen, are properly vented outside, and run the fans during showers and while cooking so humid air isn’t trapped inside.
- Keep household plants healthy by not overwatering them and making sure their soil can drain well.

Though most species are harmless to humans, prolonged exposure to any mold can pose health risks. These are most often characterized as allergic reactions.
Allergies and asthma are the most common reactions to Cladosporium exposure, though eye, ear, and sinus infections, as well as skin problems, can also result.
People vary in their susceptibility to mold exposure – some show no adverse effects while others may experience a range of symptoms such as sneezing, itchy throat and eyes, coughing, and watery eyes.
In some cases, prolonged mold exposure can lead to a condition called allergic fungal sinusitis. This condition results from the growth of mold spores in the sinus cavities, and can cause a range of symptoms including nasal congestion, postnasal drip, and recurring headaches.
Exposure can sometimes trigger severe asthma attacks, the symptoms of which include:
- severe shortness of breath
- difficulty breathing
- chest tightness and pain
- symptoms that do not respond to a fast-acting inhaler

- Practicing good hygiene, such as washing your hands regularly and avoiding contact with contaminated surfaces.
- Avoid exposure to the fungus, by wearing protective clothing and using respiratory protection if necessary.
- Keep your home clean and free of mold and mildew.
If you think you may have an infection, it is important to see a doctor as soon as possible. While most cases are mild, some can be quite serious, and early treatment is essential.
How are Cladosporium-induced allergies treated?
The treatment for any mold infection depends on the type of infection and the individual’s sensitivity to the fungus. Treatment for all mold allergies typically involves limiting exposure to the mold by removing it from the home and taking steps to prevent its growth.
Additionally, over-the-counter antifungal medications and prescription allergy medication can help to relieve symptoms.
For severe allergies, immunotherapy may be necessary. This treatment involves gradually exposing the patient to larger and larger amounts of Cladosporium until they build up a tolerance.
Nasal rinses can also help to relieve symptoms by washing away mold spores that have settled in the nose.
