Mold Allergies and Allergy Triggers

    Molds are made up from a large group of organisms that are found throughout nature, and therefore cause a wide range of allergy symptoms.


    Allergic asthma and allergic rhinitis are known to be caused by mold.

    Unlike plants, molds need food and water in order to survive and grow. Mold typically gets its food from various forms of carbohydrates, such as wood or cellulose.

    Mold grows in units called mycelium and reproduces through the generation of spores. It’s these spores that usually become airborne, and very much like pollen, can cause allergic reactions.

    It is well documented that mold causes human allergy and disease.

    Mold (fungal) infections of various types can affect humans, especially those with weakened immune systems. These fungi can also produce toxins, which can cause various diseases. Molds can also cause severe immune reactions due to colonization in the lungs (hypersensitivity pneumonitis) and the sinuses.

    It is also known that mold cause various allergic reactions such as allergic asthma and allergic rhinitis.

    The following molds are the most likely causes of allergic reactions:

    • Alternaria - A common outdoor mold; severe asthma and allergic rhinitis are associated with this mold
    • Aureobasidium – A common outdoor mold found on paper, lumber and painted surfaces
    • Aspergillus - A common indoor/outdoor mold that can cause allergic bronchopulmonary aspergillosis
    • Cladosporium - This is the most common outdoor mold
    • Penicillium - A common indoor mold (this allergy is not associated with antibiotic allergy)
    • Epicoccum - Found in grassy or agricultural areas
    • Fusarium - Found on decayed or rotting plants
    • Helminthosporum - Typically found in warm, temperate climates
    • Phoma - An outdoor mold common during wet periods
    • Rhizopus and Mucor - Found on decaying leaves and humid indoor areas (airborne varieties of these molds are less common)
    • Smuts – Spores found in large quantities in areas of agriculture
    • Yeasts - Airborne spores typically found during rainy periods in agricultural regions

    Since, as mentioned above, pollens and mold spores are part of the outside air, it’s impossible to avoid them unless you completely isolate yourself indoors. However, discovering the source of a particular mold along with your sensitivity to it will certainly move you in the right direction in order to avoid it. Equally, you will learn to create a healthier indoor living environment.

    Mold Allergy Triggers - When Do Mold Allergies Occur?

    In winter climates, molds are found in the outdoor air starting late in the winter, and peak late in the summer through the early fall months (July to October). In warm climates, mold spores are usually found throughout the year, with peak levels seen in the late summer to early fall months.

    While indoor molds can occur year round and depend on humidity levels inside the home, indoor mold levels are typically higher when outdoor mold levels are higher. Thus, a common source of indoor mold comes from the outside environment, although it can also be caused by indoor mold contamination (such as from a water leak, food spills, pets, etc.)

    Usually the biggest source of indoor mold is caused from exposure to the outdoor air. However, in humid areas, such as kitchens, bathrooms and basements, mold can grow and produce large amounts of indoor spores, causing an increase in allergic rhinitis symptoms.

    If mold or mildew is found in the home, a diluted (5 to 10%) bleach solution can be used to clean and kill the mold. Make sure water leaks are fixed, and try to increase ventilation in these moist areas, such as using a de-humidifier to limit or stunt mold growth. In areas where water damage or significant mold growth can be seen, contaminated materials should be removed.
