Mold, fungus and mildew thrive in dark, moist, poorly ventilated areas. Kitchens, bathrooms, laundry rooms and basements that are not properly cleaned and waterproofed are prime targets for this problem. Mold and fungus can cause disease, sinus infection and respiratory problems for even the healthiest of people, let alone those with compromised immune systems, breathing problems or allergies. The best way to kill mold and fungus in your home is to clean thoroughly, eliminate water leaks in pipes and walls, increase air ventilation and provide abundant light.
Look around your house for additional sources of light. If your curtains are heavy and dark, replace them with lighter materials and shades. Open blinds during the day. Turn on fans after using a shower or bath to help wet, dark areas dry out quickly, preventing mold and fungus from taking hold.
Install recessed lighting in dark, moist areas in bathroom ceilings and over shower areas to supply strong light as well as heat that can dry areas where mold and fungus grow. Kitchen ceilings also are good for this type of light fixture. Many recessed lights can be installed with timers that keep the lights on after you finish showering or leave the kitchen, and turn them off automatically 10 to 15 minutes later. If you can't afford recessed lighting, install extra lamps and stronger-wattage light bulbs to increase the amount of light the room receives.
Open windows to increase light and ventilation. Even if a window covers a screen, when it's raised, it will admit more light. Vacuum up mold spores on a regular basis after cleaning.
Take a walk around the outside of your house, and note where tree limbs are shading windows and doors. Prune back foliage to increase the amount of light that reaches your home's interior.
