Molds are simple microscopic organisms found virtually everywhere, both indoors and out. They are part of the fungi family and their function in ecosystems is to break down dead materials.
Mold needs only two things to thrive: moisture and nutrients
Moisture in homes can come from leaky roofs or plumbing, but less obvious sources, such as condensation and humidity, can create even more complicated mold issues. Many homes have dampness that allows molds and bacteria to grow, often resulting in allergic reactions, respiratory problems, and spread of infectious diseases.
Your home is a rich source of mold nutrients
Common construction materials such as wood, fiberboard, sheetrock, and paper all contain nutrients favorable to mold growth. Once mold contamination begins, the molds excrete enzymes that allow them to consume these nutrients, eventually destroying the entire building if allowed to grow and spread unchecked.
Mold growth can sometimes be observed as discoloration ranging from white to orange, or from green to brown and black.
Health effects
Inhaling mold spores can lead to adverse health effects. Some types of molds produce toxins, called "mycotoxins." Spores can also exacerbate allergies and cause respiratory irritation.
Excessive mold exposure is not healthy for anyone, and those with asthma and allergy sensitivities should be especially careful to avoid exposure (Source: EPA Web site). Severity of symptoms depends on the individual. Young children, the elderly, and persons with compromised immune systems are at greatest risk.
