Since you cannot remove all food sources for molds, it is important as a homeowner to take sensible precautions to prevent moisture from creating a breeding ground for mold.

• Maintain levels of humidity below 60% (preferably between 30% and 50%) by
  • venting bathrooms, dryers and other moisture-generating sources to the outside
  • avoiding blockage of air conditioning vents
  • using air conditioners and de-humidifiers
  • increasing ventilation by installing additional crawlspace and attic vents, opening windows or installing an air-to-air heat exchanger
  • using exhaust fans when cooking, dishwashing and cleaning
  • avoiding the use of unvented heaters or high heat in confined areas
  • setting the air conditioning thermostat to "auto" to prevent circulation of humid air.
• Add insulation to reduce the potential for condensation on cold surfaces (windows, piping, exterior walls, roof or floors).
• Consider using moisture sensors that sound an audible alarm when a leak occurs.
