Black mold spores are some of the dangerous microorganisms that grow inside of homes. Molds usually grow in moist or wet areas, but most types of molds do not really carry a health hazards to home owners. Black mold spores are a different story because these microorganisms can cause lung irritation, difficulty in breathing, etc. Therefore, when this type of mold is spotted inside a home, it should be cleaned immediately. Here are some steps to identify black mold.

Step 1 – Inspecting the Home

There are many places where black mold spores can grow, and it is worth the effort to inspect these areas to ensure family safety. Look into areas which are exposed to large amounts of moisture, such as the basement, the subfloor, the bathroom, cabinet interiors, etc. Inspect for rotted wood as well because molds can grow there.

Step 2 – Look for Dark Greenish Growths

Black mold spores have a dark green color, and they are usually easy to spot because other molds have a lighter color. When inspecting molds, do not attempt to touch them or rub them away because they may cause discomfort. It is also important to make use of a safety mask in case the spores are airborne. Understand that although black molds are not toxic in nature, they do release mycotoxins during metabolism that may irritate the lungs and cause difficulty in breathing.

Step 3 – Check for Circular Patterns

Like other microorganisms, black molds form a definite pattern when they propagate. An infected surface will have circular dark patterns all over so it is pretty much easy to know if black mold is the culprit. Nevertheless, there are some instances when the patterns are not exactly circular. Since molds grow only where there is moisture, they may not form a circular pattern when there is a portion that lacks moisture. Therefore, do not always expect black molds to form exactly circular patters all the time.

When black molds are still propagating in a moist portion or surface, they will look like dark green slimy patches. However, they become dusty when they dry. When dried, they may also lose their circular pattern because some of them fall off or become airborne.

Step 4 – Check for Signs of Black Mold Infestation

When some members of the family experience difficulty in breathing, nasal congestion, skin irritation, and recurring allergies, then make sure to check for signs mold attack. This is important especially if there are children, who still have weak immune systems, occupying the home. Make sure to check cabinets, floors, walls, ceilings, etc. Even carpets and other upholstery can be infected with black mold spores.

Step 5 – Act Immediately

The first line of defense when spotting black molds is to spray it with bleach. This kills and prevents it from spreading further up the walls, into the floor, and into other areas of the home. You can also try these ways to kill black mold. Call a professional home cleaner to take care of the rest.
