Mold is related to fungi and comes from microscopic spores that live everywhere outside. Molds are a natural occurrence and play an important role in soil fertilization and decomposition. Mold spores are usually carried inside the home on the wind, by pets or on articles of clothing. The mold spores themselves are usually not a problem unless the environment is conducive to mold growth.
Mold-friendly Environments
Mold grows in warm, dark, moist aerobic environments with a good food supply. Molds aren't picky, so any organic material--wood, plaster, dirt--will do. Bathrooms are prime breeding grounds for mold because of high moisture and available food supply.
Mold Types
There are more than 100,000 different types of mold, and some are toxic. Cladosporium, aspergillus, mucor, alternaria and penicillium are all common household molds and are not considered toxic.
Toxic Mold
Strachybotrys and memnoniella are both toxic molds and need moist plant matter, like wood, to grow. The mold may appear slimy when wet and have white edges. Contact with large quantities of toxic mold spores makes people seriously ill. If toxic mold is suspected, it should be removed by professionals.
Prevent Mold
The best way to prevent mold is through moisture control. Dehumidifiers and ventilation fans are two ways to control moisture levels. Painting woodwork with antifungal paint will also prevent mold growth.
Kill Mold
Bleach-water is effective in killing mold, and there are also several fungicides on the market that kill mold. However, if the mold infiltration is severe, the infected object may need to be removed to completely remove the mold.
