Mold is a type of fungi that grows in multicellular structures called hyphae. These hyphae produce the mold spores that are found indoors and outdoors. Although mold spores are found everywhere, in order to grow, mold requires moisture. Therefore, mold can be particularly prevalent in refrigerators and shower rooms, after a water pipe leak, or in the aftermath of flooding. There are thousands of different species of mold; some are used to produce common things like medicine (namely penicillin) and foods. However, when mold grows in your home or business, it can be detrimental, causing property damage and health issues.
