Lower Humidity

• Because mold is attracted to areas with a lot of moisture, the easiest way to prevent mold from growing is to lower the humidity in your home. One way to do this is to install a better ventilation system in your home. Another is to install a dehumidifier that will actually remove water vapor from the air. Open doors and windows if your room is humid.
  
  

Fix Leaks

• Fixing leaks will help ensure that excess water is not entering your home. If leaks are allowed to remain in your home, the excess water will run down walls or crawlspaces, which will attract excess mold spores. Check plumbing often to ensure that it is working properly.
  
  

Enhance Air Circulation

• Air circulation will lift microscopic mold spores from surfaces in your home, which will prevent them from growing and reproducing to form visible mold growth. Enhance air circulation by installing ceiling fans and bathroom fans in your home. These will also help ensure that water evaporates faster.
  
  

Clean Mold Growth

• Cleaning mold growth as soon as you notice it will prevent more mold from growing in your home. Once mold grows in your home, the mold spore count in your home's air will increase drastically, which will result in more mold growth in your home. Check shower curtains and other surfaces in your home for mold growth, and remove it as soon as you notice it.
