Household mold is a naturally occurring fungus — as well as a scourge of homeowners.
With mold, airborne spores settle and grow in warm, damp places such as bathrooms, basements and water-damaged walls. Mold has a distinctive musty odor, and you might smell it before you see it. It has a thickness to it, looks fuzzy or slimy and comes in a wide variety of colors.
Some individuals experience allergic reactions to mold, including coughing, wheezing, runny nose, red eyes and skin rashes.
These are the four common varieties found in homes:
Your bathroom is a common location for mold, with cladosporium growing above the waterline in toilet bowls. On shower walls that aren’t cleaned regularly, you’ll often find alternaria. In the kitchen, mold is primarily found on old food. This is penicillium; food with mold should be thrown out, but no other steps are needed.
The more insidious types of mold are usually found in places you don’t necessarily expect. Alternaria, because it needs less moisture than most molds, can grow on or under wallpaper as well as within carpeting in damp rooms. It can also grow in walls that have a plumbing leak or condensation drips.
Aspergillus, the most dangerous of the common molds, thrives in areas of major water damage, either from flooding or a significant chronic plumbing leak. It can be found between or behind walls and ceilings, and thus often isn’t visible from the living area of your home.
