Which Household Molds Are Most Dangerous?


Mold and its spores live practically everywhere on the planet and while most are harmless to humans, some are highly toxic. Mold is nature’s way of decomposing anything organic, including the wood, drywall, fibers and food you keep in your Toledo OH home.

However, a few strains of mold have highly toxic effects on people and require professional remediation to remove them, especially black mold and aspergillum.

What Is Black Mold?

moldStachybotrys chartarum (SC), commonly called black mold, has a greenish-black tint may have a slimy green-blackish or a powdery grey to sooty powdered appearance. You’ll find it on high-cellulose surfaces that have experienced a good deal of water damage. Fiberboard products, wood, hay, wicker and cardboard are susceptible to SC.

To date, it’s the most dangerous mold identified by the health and medical community. Its first report of toxicity came in the 1920s, when horses and cattle began to die after eating hay infested with black mold. The spores of this particular mold were also used during the Vietnam War in the 1970s as a biological weapon.

Black mold causes a variety of health problems, from minor to fatal, ranging from lung and other organ hemorrhaging to immune system suppression and sore throats or hair loss. Prolonged exposure intensifies its toxicity.

Before undertaking a mold remediation project, the only way to know if it’s present is to have it tested by a reputable laboratory, since other kinds of mold resemble SC. Black mold is difficult to eradicate because it tolerates temperatures as high as 500 degrees F and can last for millions of years. Disinfectants like bleach or acids won’t kill the mold or its spores.

What Is Aspergillum?

Unlike black mold, aspergilli have some important applications in the production of certain alcoholic beverages, medicines, and food additives like citric acid and lactose. However useful it may be in food and medicine, it can be toxic to some populations, and it’s one of the most common molds.

It grows in decaying vegetation and inside insulation or ductwork used for heating and cooling systems. Not all strains of aspergilli produce toxic reactions, but for those that do, respiratory problems are the most frequent symptom. Anyone with a compromised immune system, lung problems, or who is exposed to the aspergillum spores over a long period could be susceptible.

Mold Management

Mold growth can cause unexplained health issues and it’s important to address it if you find it growing inside your home. Since prolonged exposure may intensify the health problems associated with mold, accurately testing and diagnosing it can prevent serious disease and discomfort.

If laboratory results are positive for black mold or aspergilli, a professional mold remediation service is your only option. These specialists use pressurized equipment with HEPA filtration, wear hazmat suits, and treat the area with disinfectants to remove the mold and treat the rest of the indoor environment to prevent a reoccurrence. Mold spores are microscopic in size and spread easily. They’ll rapidly grow back without the extreme treatments that professionals provide.
