Mold only needs a few simple things to grow and multiply:
Of these, controlling excess moisture is the key to preventing and stopping indoor mold growth.
Health effects from exposure to mold can vary greatly depending on the person and the amount of mold in their home.
The type of health symptoms that may occur include coughing, wheezing, nasal and throat conditions. People with asthma or allergies who are sensitive to mold may notice their asthma or allergy symptoms worsen. Individuals with severely weakened immune system who are exposed to moldy environments are at risk of developing serious fungal respiratory infections.
The Minnesota Department of Health recommends that people consult a medical professional if they are concerned about the effects of a moldy environment on their health.
Investigate don't test. The most practical way to find a mold problem is by using your eyes to look for mold growth and by using your nose to locate the source of a suspicious odor. If you see mold or if there is an earthy or musty smell, you should assume a mold problem exists.
Other clues are signs of excess moisture or the worsening of allergy-like symptoms.
The Minnesota Department of Health does not recommend testing for mold. Instead, you should simply assume there is a problem whenever you see mold or smell mold odors.
Testing should never take the place of visual inspection and it should never use up resources that are needed to correct moisture problems and remove visible growth.
