Mold is a living organism. For mold to thrive, it requires nutrients, water and suitable temperature. If we can deny mold any one of these requirements we can completely control it's growth. It is practically difficult to manipulate the temperature or to eliminate the nutrients. However, we can control moisture or humidity in our houses. The key to mold control is to keep our houses dry all the time. Regularly vacuum cleaning of dusty surfaces such as the carpet also help to reduce the amount of settled spores which actually give rise to new mold growth when water becomes available.
