Are Dead Mold Spores Harmful? | Mold-B-Gone (2024)

YES, Dead Mold Spores Are Harmful!

YES, Dead Mold Spores Are Harmful!

Dead mold spores are just as harmful as live spores.” (Johnny Wells, Mold B Gone)

One of the problems with the mold remediation industry is the lack of regulation. Because of this, there are many contractors that believe they can offer mold removal services without the proper training or experience.

This is particularly true when you encounter mold removal contractors that recommend that mold can be simply killed. The problem with this approach is that it is not a permanent solution to a mold problem. In short, there is no “quick fix” for mold contamination situations. As a consumer, you need to be cautious about hiring contractors that offer magical solutions that involve just spraying a chemical to kill the mold dead.

As stated by Michael Pinto, CEO of Wonder Makers Environmental:

“Killing mold, but leaving the residue in place, is not acceptable. Since many health impacts can be triggered by exposure to both live and dead mold spores, the source and secondary contamination must be removed.” (MOLD INDOORS: Killing it is Not Enough)

Mold 101: The Basics

  1. Mold thrives when moisture is present. Removing mold without addressing the cause of the problem, ie. identifying the moisture source is not a long term solution. Before any mold removal, the moisture problem must first be found and fixed.
  2. Exposure to mold spores, both live and dead, and their byproducts like microbial volatile organic compounds (MVOCs), mycotoxins, connecting filaments, etc. can cause illnesses ranging from minor allergic reactions, respiratory problems like asthma and sinusitis, to more serious, life threatening illnesses.
  3. With respect to health, every individual responds to mold differently. Some people get sick, others don’t. A little bit of mold can make some residents of a property sick, but will not have an impact on others. Research has shown that 25% of the population have a genetic predisposition to mold illness and the condition known as Chronic Inflammatory Response Syndrome (CIRS).
  4. Mold is a biological agent that will continue to grow as long as the right conditions exist. This is the reason that mold is such a concern because it will continue to thrive and grow unless it is removed and the underlying moisture cause is fixed. In short, ignoring a mold problem will make the situation worse and pose more dangers.
  5. Contractors trained in mold removal, refer to the process as “remediation” because they have invested in specialized training and equipment and take precautions to prevent the spread of the mold in other parts of the building. Mold remediation specialists will never recommend a “quick fix” because they understand that relying on mold sprays, bleach, biocides, and fungicides are an ineffective “short cut” to mold removal.

The Bleach Myth!

“Perhaps the most misunderstood aspect of bleach when proposed as a cleaner or sanitizing agent is that its effectiveness is greatly reduced in the presence of organic material. To be a successful sanitizer, bleach must be used on clean materials and surfaces. This is why bleach products are used in the laundry after the wash cycle or in a commercial kitchen as a component in the third sink after the dishes have been washed and rinsed. The efficacy of bleach as a sanitizer is also compromised by heat and light. Despite the fact that the chlorine odor may linger for some time after use, bleach loses strength so quickly that it is not considered to have a residual effect that would prevent future bacterial or fungal growth.” (Michael Pinto, Why Restoration Professionals Should Avoid Using Bleach)

One of the benefits of the Internet is it allows anyone to search for a topic of interest and find the information they are looking for.

Unfortunately, with respect to mold removal, the bleach myth is perpetuated on the Internet on countless websites.

Bleach may have some impact on non-porous materials, like bathroom tiles, but bleach is completely ineffective on porous materials:

If you spray bleach all over your “black toxic mold” you won’t kill every single spore….To kill every single mold spore using bleach, for example, you’d have to use such a high concentration of disinfectant and you’d have to keep it on the surface for so long that more likely you’d damage the structure – and still miss some toxic spores.” (How to Kill Mold – Do We Want to? Is Dead Mold Dangerous?)

Other reasons we do not recommend the use of bleach:

  1. Bleach does not address the cause of the mold problem!
  2. Bleach is dangerous!
  3. Bleach evaporates!

Bleach Does Not Address The Cause Of The Mold Problem!

Experienced mold removal specialists understand that the most effective way to deal with mold is to first find the moisture source and make sure it is fixed.

The next step is to remove the mold contaminated porous materials.

Proper removal of mold contaminated materials like drywall, carpet, soft goods, insulation, and other porous materials is essential because mold has hyphae, which are basically roots that embed themselves in the material.

This is the reason that bleach does not work. Bleach may kill some of the surface mold, but it will not be able to penetrate and kill the roots.

The other reason bleach is a problem is that it is diluted with water. Spraying this is counter-productive because water is an essential ingredient mold needs to grow.

Keep in mind, even if another biocide or fungicide is sprayed on the material, killing the roots, the material will still be contaminated with dead spores. The best course of action to permanently deal with a mold problem on porous materials is to properly dispose of the contaminated material.

Bleach Is Dangerous!

When you are using bleach you should always wear gloves, goggles, and a respirator for three key reasons.

  1. Bleach is a corrosive that could irritate and damage your skin.
  2. During the spraying and evaporation process, bleach releases chlorine gas that will impact the eyes and respiratory system.
  3. One of the by-products of chlorine bleach are dioxins, linked to cancer.

If you intend to use bleach for household cleaning projects, never mix it with other cleaning solutions or detergents that contain ammonia because toxic fumes will be produced.

Bleach Evaporates!

The core ingredient of bleach is chlorine. Over time, chlorine can evaporate and escape through the plastic container. In short, the longer bleach sits, the more ineffective it will become because the chlorine dissipates.

Final Thoughts: Killing Mold Is Not The Answer!

Even if in theory we could “kill” every spore, the assumption that they are unimportant is highly questionable. “Dead” spores often contain allergens or toxins that are just as harmful to someone breathing them or getting such mold in one’s eye or in a cut, as before….The object is not to “kill” mold, it is – to remove the mold reservoir in the building by physical cleaning or in cases of items that can’t be cleaned, such as drywall, soft goods, carpets, furniture, or insulation, remove the moldy material – to identify the cause and make sure that’s been corrected.” (How to Kill Mold – Do We Want to?

FAQs

Are Dead Mold Spores Harmful? | Mold-B-Gone? ›

“Both live and dead mould and mould fragments contribute mycotoxins and other mould products which have been shown to retain their antigenic and/or toxic properties over extended periods of time.” Dead mould fragments are still toxic.

What happens to dead mold spores? ›

As you can see, mold does not die when it dries out. Instead, it enters a dormant state and can reactivate once moisture is reintroduced. Therefore, simply drying out mold-infested areas is not enough to eliminate the problem. Mold spores can still pose risks even when they appear inactive.

Should dead mold be removed? ›

Removal and cleaning are important because even dead mold may cause allergic reactions in some people. To prevent mold growth, clean wet items and surfaces with detergent and water.

Is inactive mold toxic? ›

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.

Is dry mold still toxic? ›

Is Dry Mold Dangerous to Your Health? Yes! Dry mold is just as dangerous as active mold because as we've mentioned, they can still release mold spores. This can endanger your family members with respiratory complications and compromised immune systems.

How to get rid of dead mold spores? ›

While ammonia can kill surface mold, dead mold and dead mold spores are still allergenic so you would need to make sure to remove them as well. Create a solution of 50% clear ammonia and 50% water in a spray bottle. Spray the solution on the moldy areas.

Does ventilation get rid of mold spores? ›

Improving ventilation in living areas may provide some quick relief if the mold spores in your home are a result of moisture issues or visible mold growth. The principle behind this is to allow dirty indoor air to flow outside while allowing fresh air to flow inside.

Is it bad to clean black mold without a mask? ›

When cleaning mold, you must protect yourself from mold exposure, which can have potentially harmful effects on your health. Wear an N95 mask. These masks filter particles in the air, like mold spores, so you don't breathe them in.

Does dead mold release mycotoxins? ›

The IICRC emphasizes that even dead mold remains toxigenic and allergic. Further, research has shown that the mycotoxins (mold poisons) produced by some molds are being produced on the surface of the spore and continue to move into the air even if the mold is non-viable (dead).

How to tell if mold spores are dead? ›

To confirm it is dead, brush the surface with a broom. It is most likely dead if it easily brushes off and becomes airborne. Note that “dead” mold isn't actually dead. Rather, it is inactive because it is no longer exposed to moisture.

How long do mold spores stay active? ›

Unfortunately, mold spores can remain airborne indefinitely, especially when mold is present, not fully removed, or disturbed in your home. And even if mold is not currently present in your home, mold spores can travel long distances—attaching to you or pets or entering through ventilation.

Will mold stop growing if moisture is removed? ›

The mold spores will not grow if moisture is not present. Indoor mold growth can and should be prevented or controlled by controlling moisture indoors. If there is mold growth in your home, you must clean up the mold and fix the water problem.

How long can mold spores stay dormant? ›

Mold starts with spores that can lie dormant indefinitely. Dormant spores stay inactive if they don't sense the right combination of moisture, temperature, air, and food. When something changes, the dormant spores start actively growing mold.

Do you have to throw everything away with mold? ›

Like moldy clothes, moldy furniture can sometimes be saved, depending on the time and amount of mold exposure. If you attempt to clean your moldy furniture and it doesn't budge, then you'll need to dispose of the item.

What are the 10 warning signs of mold toxicity? ›

The ten warning signs of mold toxicity include respiratory issues, allergic reactions, skin irritations, cognitive and neurological symptoms, fatigue and weakness, and digestive issues. By recognizing these symptoms, you can identify potential mold toxicity in your environment and take appropriate action.

Can mold spores be destroyed? ›

There are many ways to deal with mold growth in your home, and extreme heat is one of the most tried-and-true ways to kill those pesky spores. Unfortunately, even dead mold can contain dangerous toxins that cause allergic reactions and other health effects.

How long do mold spores stay in the air? ›

They remain airborne for an indefinite period. It is important to recognise that if a damp spot is present and unattended for longer than 24 hours, there is a high possibility that mould could fester and airborne spores might begin congregating throughout the premises.

How long do mold spores live on dry surfaces? ›

Without a constant supply of water, mold will “go to sleep”. However, the spores never actually “die” considering that they can come back to life once more moisture becomes available. Depending on the type of mold, some spores can remain dormant for hundreds of years under the right circ*mstances.
