| − | + | Black mold is a type of fungus that can grow indoors. Like all molds, black mold loves moist environments, so areas that are often damp, such as wet basements, showers, bathrooms, and areas where there's a leak, are prone to mold growth. Because some kinds of black mold can cause allergic reactions, asthma attacks, and respiratory issues, it’s important to remove it when you do find it in your house. The trick to killing black mold is penetrating the mold and killing the roots as well, and taking steps to ensure it doesn’t return. | |

| − | # Seal the area. To prevent mold spores from becoming airborne and spreading, you can seal the room. Put up sheets of plastic to cover doors and vents that lead to other areas of the house. Use painter’s or construction tape to tape the plastic in place and seal the room.<ref>http://moldmanusa.com/mold-remediation-and-mold-removal-explained-in-plain-english/</ref> | + | # Seal the area.

# Turn on vents and fans. To provide extra ventilation and circulation while you're working, set up some fans and turn on vents that can blow air from the room outside. This will blow any mold spores outside rather than letting them float around in the air. | # Turn on vents and fans.
