What's the Difference Between Mold and Mildew?

Because mold and mildew commonly grow in the same types of environments -- warm, damp areas -- they are often mistaken for one another. In actuality, mold and mildew are different types of fungi despite sharing many similar characteristics, including spreading out from spores. Mildew is found more often in showers, fabrics and paper, while mold is more often found in foods. Mold can range in color from black to red to green, while mildew is typically white or gray.

Although both mold and mildew can be problematic for individuals with allergies or asthma, it's typically mold that causes people to be most weary. That's because some molds have toxins called mycotoxins to which some people may be severely allergic. Inhalation of certain molds can also cause respiratory problems.

Mildew can generally be cleaned off of hard surfaces with a mildew cleaner or a bleach-and-water solution. If mold is very prevalent in a home, it may be best to call in a professional to determine the best course of removal to prevent spores from spreading and causing health problems.
