Can dead mold be harmful?
Both dead and living molds produce allergens, irritants, and potentially toxic substances that can impact your health and cause allergic reactions when inhaled or touched. Let professionals, like us, handle the removal of dead mold in your home to prevent problems and adverse health effects.
Please note: Dead mold may still cause allergic reactions in some people, so it is not enough to simply kill the mold, it must also be removed.
This usually occurs even if the mold spores are inactive because they can easily become airborne when blown around with the air circulating in and out of the house. Once they become airborne, they can move from one place to another and may end up settling in an area with all the necessary conditions for their growth.
Certain molds produce mycotoxins which, depending on the exposure level, can cause health effects. Both active and inactive molds can pose potential health hazards. Health effects from mold can be acute from short-term high exposures or chronic from long-term exposure to lower levels.
Further, research has shown that the mycotoxins (mold poisons), produced by some molds, are produced on the surface of the spore and continue to get into the air even if the mold is nonviable (dead).
Mold will not completely die, but it will dry out. Humidity levels between 30%-60% are preferable in the prevention of mold growth. Warm air absorbs more moisture than cold air.
Dry mold can still present health concerns.
Unfortunately, dry mold can continue to present health risks to those with respiratory conditions, allergies, or other sensitivities. Because dry mold is more likely to become airborne, it's more likely to affect overall air quality, too.
Use a bleach solution of no more than 1 cup (8 ounces) household laundry bleach per 1 gallon of water to kill mold on surfaces.
Risks of Black Mold Exposure
Chronic coughing and sneezing. Respiratory irritation. Skin disorders, including rashes. Chronic fatigue.
In fact, dry mold can be an equal if not greater threat than wet mold, despite no longer being able to produce billions of mold spores. Since the mold spores already out in the open have dried out, they become lighter, thus making it easier for them to become airborne and spread throughout your home.
How long do mold spores stay in the air?
Can You Get Rid of Mold Spores in the Air? Mold spores are constantly all around us. Due to their size (between 2-100 microns), they're invisible to the naked eye and can stay in the air indefinitely.
Dead mold has a powdery, flaky appearance. To confirm it is dead, brush the surface with a broom. It is most likely dead if it easily brushes off and becomes airborne.
These symptoms usually first appear 2 to 9 hours after exposure and last for 1 to 3 days. Other affected persons have progressive shortness of breath and cough, as well as weight loss.
Identification of Mold
This is more easily seen under magnification. Active mold is soft and may smear when touched with a fine brush. It may also be slimy and damp. Inactive mold is dry and powdery and will seem to brush off materials readily.
Respiratory symptoms such as wheezing, coughing, watery eyes, and skin irritation are the predominant symptoms. Mold is also known to cause asthma and life-threatening primary and secondary infections in immune-compromised patients that have been exposed.
Some people confuse mold staining with dead mold.
These are not the same. Some molds can indeed leave behind stains on certain building materials after the mold itself has been removed. A word of caution with this however. A mold stain may still have inactive mold spores lurking deep inside the building material.
Molds, along with mushrooms and yeasts, are fungi and are needed to break down dead material and recycle nutrients in the environment. For molds to grow and reproduce, they need only a food source – any organic material, such as leaves, wood, paper, or dirt— and moisture.
The mycotoxins produced by black mold can be breathed in, ingested, or absorbed through a person's skin. After prolonged exposure, these mycotoxins find their way into the person's bloodstream.
“Humans cannot smell most mold toxins, especially after the mold is “dead.”” This quote came from a company website. However, the EPA says: "Some compounds produced by molds have strong smells and are volatile and quickly released into the air.
Most yeasts and molds are heat-sensitive and destroyed by heat treatments at temperatures of 140-160°F (60-71°C). Some molds make heat-resistant spores, however, and can survive heat treatments in pickled vegetable products. These molds, however, require oxygen to grow.
Does cleaning mold release spores?
During the cleanup of mold, many spores may be released into the air. To prevent health effects, there are several ways you can protect yourself while cleaning up the mold.
The only way to directly kill mold spores in the air is to use an air purifier. For best results, place purifiers in each room of your house to ensure maximum efficiency in killing the spores. You can get a quality air purifier at any home improvement store and at most mass retailers.
Black mold, as the name implies, is often dark in color. When searching for black mold, look for circular-shaped spots that are black, dark green or dark brown. Some black mold can also take on shades of orange or have flecks of white within it. Most of the time, black mold has a slightly furry appearance.
For a natural solution for getting rid of black mold, combine one part baking soda with five parts distilled white vinegar and five parts water in a spray bottle. Alternatively, you can use a chemical-based mold and mildew remover, all-purpose cleaners, bleach or dish soap.
Sodium Hypochlorite has been found to kill trichothecene and other mycotoxins. Extreme heat (fire at 500°F for half-hour) can destroy trichothecene mycotoxins. Ozone can kill most mycotoxins, but the level needed is not safe for humans. HEPA air filters need to be supplemented with activated carbon filters.
White distilled vinegar is an affordable, natural solution to removing black mold. Its antibacterial acidic characteristics are exactly what you need to get the job done. Pour the undiluted vinegar into a spray bottle to apply to the area, or just go for it and pour that vinegar right onto the mold stains.
You can remove the black mold yourself in many instances. Then the black mold can be killed and removed with cleaners like bleach, distilled white vinegar, hydrogen peroxide, baking soda, or Borax.
On the basis of current research, black mold exposure is no more dangerous than any other type of mold exposure. It is impossible to avoid exposure to mold — the spores are almost everywhere in the atmosphere. In high amounts or in people with allergies, exposure to any mold may cause allergy symptoms.
If you're not wearing any Personal Protective Equipment (PPE), you're inviting all of those mold spores to settle on your clothing, the area you're cleaning, your shoes (allowing mold to travel to other areas in your home), in your eyes, and up your nose into your upper respiratory system.
Natural fibers like cotton and wool are the most likely to host mold, but it can grow on synthetics, too. Washing and drying clothes works very well to get rid of mold on clothing. Make sure that your detergent kills mold—if not, use bleach or vinegar.
Can opening windows reduce mold?
As you might've guessed, opening windows can help reduce mold. Doing so lets excess moisture flow outside instead of settling on your walls, floors, and ceiling. Without the proper amount of moisture indoors, mold won't be able to grow. Opening windows can be helpful.
If the humidity in a room increases, mold will start growing in patches on walls, clothes, and more. So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity. If you have a mold problem in your home, don't wait. Mold spreads as long as it has a water source.
The mold spores can colonize (grow) inside lung cavities that developed as a result of chronic diseases, such tuberculosis, emphysema, or advanced sarcoidosis. The fibers of fungus might form a lump by combining with white blood cells and blood clots. This lump or ball of fungus is called an aspergilloma or mycetoma.
If you or your child display symptoms of mold exposure, see your doctor. Allergic reactions to mold may clear up with over-the-counter medications, such as antihistamines. If your allergies persist, you should also see your doctor. Asthmatic symptoms require immediate medical attention.
A blood test, sometimes called the radioallergosorbent test, can measure your immune system's response to mold by measuring the amount of certain antibodies in your bloodstream known as immunoglobulin E (IgE) antibodies.
A new study found that people affected by mold illness experienced: Brain inflammation in the hippocampus, the area of the brain that governs memory, learning, and the sleep-wake cycle. Decreased neurogenesis, or the formation of new brain cells. Impaired memory.
Many patients with memory loss and dementia are actually simply toxic from mold, which is a reversible condition.
Using Hydrogen Peroxide to Kill Mold
Spray the moldy surface completely to saturate the area with hydrogen peroxide. Leave the surface to sit for 10 minutes. Scrub the area to make sure to remove all the mold and mold stains. Wipe down the surface to remove residual mold and spores.
A bleach solution also works to kill mold. Mix one cup of bleach in a gallon of water, apply to the surface and don't rinse. Mix a 50/50 solution of ammonia and water. Spray on the surface, wait two to three hours, then rinse.
These symptoms usually first appear 2 to 9 hours after exposure and last for 1 to 3 days. Other affected persons have progressive shortness of breath and cough, as well as weight loss.
How much mold does it take to make you sick?
Generally, large amounts of mold are more likely to cause negative health effects. Therefore, the more mold is present, the more likely you are to develop symptoms quickly. However, this also depends on your body. For some people, a one-time exposure to a small amount of mold isn't enough to cause symptoms.
Can You Get Rid of Mold Spores in the Air? Mold spores are constantly all around us. Due to their size (between 2-100 microns), they're invisible to the naked eye and can stay in the air indefinitely.
Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin. Some people, such as those with allergies to molds or with asthma, may have more intense reactions.
The most common black mold symptoms and health effects are associated with a respiratory response. Chronic coughing and sneezing, irritation to the eyes, mucus membranes of the nose and throat, rashes, chronic fatigue and persistent headaches can all be symptomatic of black mold exposure or black mold poisoning.
