Is Indoor Mold Causing Your Allergy Symptoms?

What are the facts about the connection between indoor mold growth and allergy symptoms? Mold and the microscopic airborne spores it releases are ubiquitous on planet Earth. In fact, you’re probably inhaling mold spores at this moment. Of the nearly 100,000 mold species in nature, however, only about 12 types are typically found inside houses.

According to the Centers for Disease Control and Prevention, health issues due to mold growth are primarily related to:

  • The extent of exposure. The concentration of mold spores in outdoor air is very dilute. However, airborne spores released by active, growing mold inside the enclosed environment of a house may accumulate to very high levels. This elevated daily exposure may cause allergy symptoms in susceptible persons.  
  • Mold type. Individual sensitivity to mold varies widely, as do potential symptoms. Spores released by certain mold types such as Stachybotrys chartarum carry mycotoxins which may trigger allergic reactions in some individuals. However, a specific person may be uniquely sensitive to spores from any particular type of mold—or experience no reaction at all.

How Mold Thrives

Certain conditions must exist for mold growth to gain a foothold and expose residents to possible ill effects:

  • Indoor temperature. The most conducive range for mold growth is 70 degrees to 90 degrees Fahrenheit.  
  • Food supply. Mold growth thrives on cellulose present in wood and building materials like drywall, paper, fabrics, and even household dust.
  • Moisture. Contact with moisture triggers long-dormant spores into an active mode in just 48 hours. Active growth releases airborne microscopic reproductive spores. Inhalation of reproductive spores is a proven cause of allergic symptoms in individuals with a sensitivity to mold mycotoxins.

Moisture = Mold

Moisture is the most critical factor in mold growth, particularly immediately following a water damage incident. Professional mold remediation includes these strategies:

  • Rapid response with research-proven measures to inhibit activation of dormant mold and release of allergenic spores.
  • Where mold is already established inside a house, professional remediation methods include determining the extent of contamination with air samples, tracking locations of active growth, and utilizing proven mold removal and decontamination methods, including EPA-recommended antimicrobial solutions, to permanently eliminate mold.
