Toxic black mold tends to form in consistently humid environments, like attics, or in areas that were subject to prolonged flooding issues, like basements, crawlspaces, and around foundations. Toxic black mold growth has a more potent and identifiable smell, like the smell of decay, wet soil, or rot.
Black mold has a distinct smell. It's often described as musty and earthy and may even smell like rotting vegetables, plants, or paper. Some think it smells like cedar. You might notice a musty smell but cannot see any mold growing.
The odor is often described as earthy or damp, similar to rotting wood or paper, and generally pungent and unpleasant. If you notice a persistent musty smell in your home, especially in areas prone to moisture, it could be a sign of toxic black mold growth.
Well, it may be because there is Stachybotrys chartarum–or more commonly known as black mold–in your home. This mold has a distinct odor that can be described as “musty” or “earthy.” Some people compare the smell to that of rotting wood or leaves… gross!
Mold, when it flourishes indoors, exudes an odor. Experts liken the smell of mold to a forest lush with earthy vegetation, soil and decaying wood. Others connect the scent of dirt lying beneath decayed leaves with the smell of mold. More homely descriptions suggest mold smells like wet, dirty socks.
At present, no test exists that proves an association between Stachybotrys chartarum and particular health symptoms. Individuals with persistent symptoms should see their physician. However, if Stachybotrys chartarum or other molds are found in a building they should be removed.
Mold exposure can cause a variety of neurological effects, including headaches and migraines, cognitive impairments, memory loss, confusion, impaired motor skills, depression, and other behavioral changes. Due to mold exposure, people with weakened immune systems may be more susceptible to neurological symptoms.
Aureobasidium
This yeast-type fungus can be mistaken for another more sinister and dangerous mold but is far less likely to make you sick. Aureobasidium can start as a slimy pink color, but it will turn brown or black and can look like black mold.
It irritates the nose and throat, which can lead to both sneezing and coughing as your body tries to get rid of the irritant. Inhaling mold spores can also trigger coughing in people with allergies or an asthma attack, for those with asthma.
Common black mold presents differently than toxic black mold. It's likely to appear in ordinary spaces, not just in water-damaged basements and humid attics. Non-toxic black mold also cleans more efficiently than toxic mold, and it doesn't possess the same musty, dirty smell that makes toxic mold so recognizable.
Detecting this scent could be crucial in identifying a mold problem before it causes too much damage. Experts describe black mold as smelling musty—comparing it to rotting wood or leaves or wet, sweaty socks.
Try Chemical Remedies. Hydrogen peroxide can kill mold and remove odors. Apply a 3% hydrogen peroxide solution to the moldy area, let it sit for 10 minutes, and then scrub and wipe clean. Alternatively, you can create a Borax, ammonia, or a diluted bleach solution to eliminate mold and the associated smells.
Colloquially, Stachybotrys chartarum is often called “black mold” or “toxic mold.” The name “black mold” refers to its color, which many people believe is unique to S. chartarum. However, this is not the case — there are many species of mold that can be black in appearance but are not S. chartarum.
If you don't see signs of mold, but you can smell it, it may be hidden in your walls. A musty smell indicates that mold is growing in your home. The smell of mold feels earthy, like rotting leaves or decaying wood in a dense, damp forest.
Known for being found in dark, dank places like many other kinds of molds, black mold has a strange musty odor—definitely not a pleasant scent for human nostrils. Some people have compared this smell to that of rotting wood or paper, while others have said it smells like cedar.
If you weren't able to identify where the moldy smell is coming from, the mold might be growing in hidden areas like ducts, air vents, HVAC, attics, or walls. Check humid and damp areas in your home where mold might be hiding. If these methods fail, consult a professional to inspect your home for mold contamination.
Repeated or prolonged exposure to high levels of some VOCs can cause blurred vision, headaches, nausea, dizziness, coughing, burning eyes, respiratory irritation, skin rashes, respiratory illness, concentration difficulties, and other symptoms.
You can use a 3M LeadCheck Swab (found at most hardware stores) to do this; be sure you swab any children's products and imported goods. Conduct a lead risk assessment by a certified inspector before any home remodel.
Dark Colored Spots On Your Walls
A key indication of mold growth is discovering discoloration on your walls. In many cases, this change of color first comes when the walls are wet. However, as mold grows, the size of the colony may lead to it being seen as a color change on walls.
