What Type Of Mold Is Affecting You?


More often than not, the question is not if, but what type of mold is affecting you. The humid Southwest Florida temps are perfect for mold to grow. Households and commercial structures are easily affected in our area. The most common question is, “how dangerous is the mold in my building?”. Most people hear the word mold and assume the worst: The infamous “toxic black mold.” However, there are thousands of species of molds, including some black molds that are non-toxic. Toxic molds are those that produce deadly mycotoxins intended to kill other organisms in defense to ensure its survival. There are generally three types of mold groups: Allergenic, Pathogenic, and Toxic.

Allergenic Molds

Allergenic molds are one of the most common mold types discovered in areas where allergy and asthma sufferers begin experiencing symptoms that cause them to investigate for the source. Allergenic molds release mold spore allergens that spark allergy and asthma responses in those affected. Around 20%-30% of the population is susceptible to mold and other common allergens, leaving behind hay fever-like symptoms. For the people that do not suffer from allergies or asthma, the small number of allergens produced by common allergenic molds does not affect their health. When a person is allergic to mold, the allergens released create an inflammatory response in the respiratory system, causing flare-ups of wheezing or coughing.

Common Allergenic Mold: Penicillium is a common allergenic mold that is easily identified by its musty odor. This fungus, found on spoiled food, fabrics, and building materials, can cause allergenic reactions in a typical household. Penicillium tends to be shades of blue, green, and white and has been known to grow on cooling coils in air conditioning units as well as interior fiberglass liners, leaving you with allergens spread through your ventilation system.

Pathogenic Molds

Pathogenic molds are known as opportunistic molds that cause certain diseases and infections in the body. While a person with a regular healthy immune system may be able to fight off the pathogens released by these molds, infants, the elderly, and those with suppressed immune systems become compromised. When this reaction occurs, the opportunity for the pathogen to take hold and cause serious illness rises, thus the name “opportunistic molds.”

Common Pathogenic Mold: Aspergillus is a fungus whose spores are commonly found in the air but do not typically cause illness to healthy individuals. However, those with compromised immune systems can experience asthma and respiratory disease flare-ups, as well as aspergillosis. Aspergillosis is an infection, most commonly in the lungs, caused by Aspergillus. This illness forms a ball of blood clots, white blood cells, and fungus fibers that block areas of the lungs or sinuses.

Toxigenic Molds

Toxic molds spread mycotoxins, a poisonous (toxic) chemical that is dangerous to humans and animals alike. Allergenic and pathogenic molds do not deliberately release harmful chemicals to hurt other organisms; the harm their category causes is simply a side effect of its species. Toxic molds intentionally cause damage as a defense mechanism to survive in most environments. Mycotoxins are known to be one of the deadliest chemicals on Earth, causing temporary illness or irritation, or long-term or permanent illnesses depending on the individual and level of exposure. The most common forms of exposure are inhalation, skin contact, and ingestion. Simply breathing the air in your home can cause severe illnesses if toxicity in the air is present.

Common Toxigenic Mold: Stachybotrys, the nefarious “black mold” everyone fears, is one of the most harmful toxic molds found in a home. The mycotoxins released by this species are known to cause fatal effects such as bleeding lungs. This type of black mold is usually tricky to detect and hides behind walls and under ceilings and can be resistant to regular air sampling.

The Rainbow Colors Of Mold

The Rainbow Colors Of Mold

The Many Colors Of Mold

When we hear the word mold, most of us picture green fuzz on spoiled food or black and green spots on the wall. Yet, there are thousands of species of molds, and each type of mold can vary in color. The different colors of mold have a tale to tell! While black and green may be the most seen molds, mold can also grow in a vast array of colors.
In this article, we’ll explore the many colors of mold, where they like to live and some potential hazards.

What causes mold to have different colors?

There have been theories of why different molds differ in color. Yet, science has provided us with some insight on why and some may even consider it fascinating. Mold colors may vary due to their age or stage and the conditions in which they are growing. Also, the colors of mold vary by region. For example, in The Amazon, orange mold is very common due to the pigments found in its food source.
Fungal biologists have found that the colors of mold act as a weapon or a defense mechanism. The color pigmentation creates a protective barrier for the mold. They even create a toxic chemical environment as an act of warfare against other fungi! Another function of color produces waste chemicals or digestive agents. The digestive agents break mold’s food source down.

Multi-Colored Mold

In the mold photo featured above, it’s easy to see there is more than only one color of mold represented. This is often the case when mold is present. Most mold reflects several colors that range from white to dark and even bright colors. Important to note, the same type of mold can, in fact, appear in several different colors. This presents a challenge in determining what type of mold you’ve found by sight alone. For this reason, a Certified Mold Inspection is always recommended.

White Mold – A color of mold often confused with mildew!

White mold is often confused with mildew. This develops due to their microscopic spores, making them complicated to detect. Once the colonies grow, the molds appear as spots across the surface of the affected area. Like most other molds, white molds thrive in wet and musty environments. White mold can grow on any organic materials such as plants, fabrics, wood, or drywall. This can prove to be a danger to your health and the structural safety of your house.
It appears as powdery, flaky, stringy, or film-like in appearance. In the early stages, it can resemble mildew. Mildew is harmless. Yet white mold can grow deep within the organic materials. When this happens, the mold compromises the material’s structural integrity. White mold can also turn from white to grey, green, or black!

Gray Mold – A color of mold more dangerous to plants than people.

Gray mold is a danger to plants. It is a necrotrophic fungus that kills its host and lives off of the dead tissue. Sounds like something off of a horror movie, right? At first, gray mold will cover only parts of the plant that is its host with grayish webbing. But, eventually, the entire plant becomes covered by this gray fuzzy growth.
Though this is deadly to plants, the risks to humans are minimal. Some have reported an allergic reaction to this species of mold. This reaction is also known as “Winegrowers Lung”. This hypersensitivity pneumonitis isn’t deadly but requires medical treatment.

Red Mold – This color signals danger.

Red mold is easy to spot and may signal danger. Some people mistake red mold as a pink mold and vice versa. There are many types of mold associated with this color, some hazardous. Only a certified mold test will be able to determine if a red mold is hazardous or not.
This color mold tends to grow alongside other molds. It’s often found on spoiled food and building materials such as wood and drywall.

Green Mold – A very common color of mold.

Green mold is among the most common species of mold and refers to hundreds of mold types. Green mold spores can, on occasion, turn blue, black, or pink. Most often, when found in a home, the spores you will discover are green in color. If you find green mold in a home, investigate areas that are moist, warm, and have organic material. Windowsills, attics, and bathrooms are especially prone to these types of mold.

Green-Black Mold – A toxic color combination.

Green-Black mold is a camouflaged version of toxic black mold, Stachybotrys. Black mold is not identifiable by sight. Like black mold, green-black mold requires a certified mold test to identify its type. This type of mold is one of the most dangerous molds that we find. It poses a hazard to your health and any living thing it reaches due to its deadly mycotoxins.
This mold is often gelatinous and slimy due to its top layer of protection. But, if this mold’s source of moisture ends it will turn to a dry and powdery texture. Whether the mold is slimy or powdery, the health risks remain the same and you should avoid it at all costs.

Olive Green Mold – A common mold that’s difficult to see!

Olive Green mold is very common in both indoor and outdoor spaces. Yet, this color mold is very difficult to see. This mold loves outdoor plants as hosts. Usually, this mold is powdery. It will form a combination of colors with gray and brown parts to it. It may be very light in color, making it hard to spot with the naked eye.
In rare cases, olive green mold can cause a brain infection called fungal meningitis. It’s linked to various eye, skin and sinus infections. This type of mold is hazardous to your health.
It loves outdoor plants as hosts. It’s often found growing in walls, cabinets and damp carpets. You may even find this mold growing on the leave of your indoor houseplants.

Orange Mold – A mold color often mistaken as rust!

Orange mold is more common than you may think. Some homeowners have orange mold present and do not realize what it is! Many mistake it for grime or rust-like build up. Orange mold differs from typical mold with its orange color and slim like appearance.
In typical mold-like fashion, orange mold grows in moist, warm places that offer a food source. But, orange mold is most likely to develop on wood rather than any other organic material. Beams, attics, rafters, and wooden window sills are among the top affected areas of orange mold. Kitchen floors and ceilings are also a high-risk area for this mold growth. Pipes and appliances expose wooden areas of kitchens to moisture making them prone to mold.

Yellow Mold – A mold color often confused with pollen.

Yellow mold often gets confused with pollen. Here is why. Both are yellow and may collect near windows or doors. Especially if flowers or other pollinating plants are nearby. It appears as dusty or fuzzy, and in some cases, may arise as a slimy gelatinous texture. This color mold often presents itself along with the white or green mold.
Slimy, yellow mold can be one of over 900 species of molds that are unlike fungi. They are single-celled organisms. Due to the single-cell structure, the slime molds are liquid or mushy in texture. Slime molds tend to feed off of plant matter in the decomposition phase found outdoors. Including in your mulch bed or leaf piles. The most common area for a yellow slime mold to be present is within the air conditioning unit.

Purple Mold – A mold color that is easy to spot!

Purple mold is uncommon in comparison to the other colors of mold. Yet, this color of mold is often found on wooden surfaces such as building material. It loves to hide behind walls, wallpaper and beneath vinyl.
This color is often dangerous as it’s usually associated with the toxic pink mold. Toxic pink mold, Fusarium, produces mycotoxins that are harmful to your health.

Blue Mold – We’re not talking cheese.

This powdery mold is usually a form of mold called aspergillus or penicillium. Some blue molds are in cheeses that we eat or used to make antibiotics. Blue mold outside of these specific types are not good for your health. The antibiotic penicillin comes from the mold called penicillium. But, breathing penicillium spores comes with risks to your health. This type of mold can cause allergic reactions, inflamed lungs, and sinus issues. This type of mold loves to grow on food but is also found in places where water damage has occurred.

Pink Mold – Don’t let this pretty color fool you.

Pink mold is usually fuzzy and produces dangerous mycotoxins. Mycotoxins are the toxic compounds that are naturally produced by certain molds. These molds are a health risk to those with weakened immune systems, the elderly and children. The risk of health issues increases as exposure time increases to these molds.
For example, running a humidifier for long periods of time can cause a pink mold to grow in the machine. If this happens, people may develop a hypersensitivity pneumonitis called “Humidifier Lung.” Humidifier Lung causes coughing, difficulty breathing and fever. Cases of “Humidifier Lung”. This type of mold is also often found growing on damp window frames, wallpaper, and carpets.

Brown Mold – A color of mold often mistaken as a simple discoloration!

Depending on the lighting and stage of development, brown mold may appear to be brown or almost black. Brown mold in early stages may seem like small areas of discoloration. People mistake mold as discoloration on walls, ceilings, bathroom tiles, or wood surfaces. At first glance, it may seem harmless to the unsuspecting homeowner.
Upon aging, the brown mold develops a thick fuzzy, or hairy appearance. If not caught in time, it can morph into mushroom-like blobs on the surface it has infested.
Brown mold can be confusing to the homeowner with a mixed appearance. This is due to the diverse strains of mold that are common for brown molds. Patches of brown molds often contain a combination of other molds. And some that produce mycotoxins that are hazardous to your health.

Black Mold – A color of mold most often associated with toxic health risks!

Black mold is the most feared of all mold colors. This is because black mold is toxic to your health in most cases. Yet, not every black mold is toxic and there are molds of other colors that happen to be toxic as well. Believe it or not, you cannot determine if mold is black by looking at it. Other colors of mold can also appear black. A specialized microscope used in a mold analysis is the only way to determine if the mold is black.
If you find what you believe to be black mold and it has a slimy appearance, chances are it’s toxic to your health. It grows easily in cellulose materials like cardboard, paper, wicker, and wood. It’s often found in humid parts of the home like the kitchen, bathroom, laundry room, and basement. Additionally, black mold is very difficult to completely remove. Many people look for ways to take care of household tasks and challenges through DIY methods. We recommend seeking certified mold remediators to tackle this type of job.

Mistaken Identity: Which Black Mold Is Toxic?

Mistaken Identity: Which Black Mold Is Toxic?

Mistaken Identity: Which Black Mold Is Toxic?

When your reputation is deadly, no one wants to be around you. In the case of Stachybotrys, also known as toxic black mold, even other molds that resemble it in color are avoided. As a home or building owner, ensuring the premises is safe for all patrons is a vital component of the landlord’s duties. If a family member or tenant states they see “black mold” in the building, the initial thought is it could be toxic. While this can be the case, it is not always true. Here in southwest Florida, the humidity levels increase the risks of mold growth, both toxic and allergenic. There are black colored molds that are not the infamous “toxic black mold,” Stachybotrys.

Black Colored Molds vs. Toxic Black Mold


Dark brown or light green features accompany Black colored molds, and the texture may vary depending on the specific species (there are thousands). Although these molds are known to be allergenic, they are not all proven to be toxic. Allergenic molds cause an allergic response in the human and animal immune system, such as itchy red eyes, sore throats, sneezing, and respiratory problems. The allergic response that occurs depends on the individual and their immune system. Pets may also have an allergic reaction should their immune systems cause a response in the presence of mold.

Prolonged exposure to any mold, allergenic or toxic, can cause an increase in immune response and should always be mentioned to a physician, or veterinarian, for evaluation.

Toxic black mold appears as dark black, sometimes accompanied by a dark green color. With a slimy texture, this mold tends to grow in areas that have been exposed to humidity for weeks, causing a desirable growth environment. Under the sink cabinets, wood structures, wet cardboard or wicker are all common locations of toxic black mold. Toxic black mold can be found indoors as well as outdoors. On average, the affected area would need to be wet or moist consistently for at least 72 hours for Stachybotrys to grow. Should this mold be identified in your home or building, inspecting for possible leaks or water damage would be an advised next step with mold remediation.

Initial exposure to toxic mold, inhaled, or ingested, can cause severe health reactions. The less severe risks can include trouble breathing, fatigue, sinusitis, or depression. However, toxic mold is also known to cause neurological problems, including decreased cognitive function, as well as pulmonary hemorrhage (bleeding from the lungs) in infants and children.

Common Black Molds


Although non-toxic, these molds are often seen and assumed to be toxic due to their appearance.

  • Cladosporium- Appears olive-green to brown/black, this mold portrays a suede-like texture. Cladosporium is frequently found within carpet, fabrics, and other upholsteries, along with wood structures such as cabinets. Cladosporium is known for disrupting the respiratory system causing issues with breathing.
  • Chaetomium- Beginning as a white-colored mold, this cotton-like textured mold darkens to gray and finally brown and black with time. Chaetomium grows within water-damaged buildings and is typically living within the roof, basement/crawl space, pipes, and drywall. Chaetomium is known for a musty smell and causing skin and nail infections.
  • Aureobasidium- ranges from pink, brown, or black, as it darkens with age. This mold is often discovered behind wallpaper or on painted or wooden surfaces. Aureobadidium is non-toxic, but this mold may cause eye, skin, or nail infections.


Should mold of any type be discovered in your home or building, calling in a professional inspector is the safest way to determine the immediate danger to anyone in the building, and the building itself. Certified inspectors are only a call away at Mold Inspectors Of Florida.

Laundry Room Mold: Inspecting and Preventing Mold in Your Washroom

Laundry Room Mold: Inspecting and Preventing Mold in Your Washroom

Laundry Room Mold: Inspecting and Preventing Mold in Your Washroom

Mold presence in laundry rooms should not come as a surprise. As most people are aware, mold growth occurs in moisture ridden areas, and a laundry room is no exception. Wet clothes in the washer are easy to be forgotten overnight, or in some cases, longer. Leaving these clothes unattended can cause mold and mildew to grow on clothes. Opening a washer to smell a pungent aroma on garments that have been sitting too long can be credited to mold and mildew growth. Remember the sound of your mother yelling not to leave the wet clothes in the hamper? She was concerned about mold growth. Due to the humidity levels that arise in a laundry room, and the presence of damp clothing, how do you properly prevent mold?

Where to Inspect and How to Prevent

Regular home inspections for mold are essential to staying on top of laundry room maintenance. Simple checks by the homeowner can save headaches in the long run. Running through a simple checklist at least twice a year is better than spending thousands of dollars in cleanup, remediation, and replacement.

Walls: Examining walls, both easily visible, and those hidden by the appliances, are important to check for mold growth. Mold can grow inside the drywall due to the moisture build-up in the laundry room. Walls with piping exposed can become especially vulnerable to mold. If you observe discolored spots or signs of leaks, this could mean mold growth.

Prevention: Regularly inspect for signs of water damage and mold growth. Clean up any spills or leaks promptly and assist incomplete drying of the water damaged area.

Washer and Dryer: Don’t let the names fool you, a washer can still be unclean with mold, and a dryer can even obtain moisture. Inspect inside the appliances for off-putting smells or discoloration. If your linens still smell after being washed, the machines may have mold or mildew growth on the inside. For front-loading washers, mildew, moisture, and debris can build up on the auto-lock features and rubber seals. Machines also have the potential to bust a leak inside the appliance.

Prevention: Place a drip pan under the washer to monitor for potential leaks. Perform regular maintenance cleanings for both the washer and washer door. Keep a timer on your phone to remember to move over the laundry to prevent mildew in the washer and dryer. Keep the lid of the washer open when not in use to assist in drying out the bin and preventing inner mold growth.

Around The Room: Regularly inspecting the floors for signs of leaks can give you ample time to act. Whether it be the washer, the utility sink, or a backed-up drain, there are several areas in which water damage can affect a laundry room. Checking the hoses and piping are also another beneficial tool in prevention. Over time, loose connections in the tubes may occur, especially if the washer becomes unbalanced.

Prevention: Pull the washer away from the wall and observe the hoses for drying or cracking. Secure any loosened tubes. Run a wash cycle while the appliance is pulled out and watch for any leaks in the tube. Pour a few cups of water down the floor drain and be sure it is working correctly. Hidden drain blockages can be problematic when an unforeseen circumstance arises.


Adding a dehumidifier into the laundry room goes the extra mile in preventing mold and mildew growth in your laundry room. When purchasing, be sure to purchase a dehumidifier that has a hose attachment, and not a collection bucket. Collection buckets you must dump continuously, hoses can secure to the drains or utility sink and ensure the dehumidifier is continuously working.

If you find signs of mold or mildew in your laundry room, call us at Mold Inspectors of Florida to help investigate the origin and severity of the mold safely.

Pets and Mold: The Hidden Poison

Pets and Mold: The Hidden Poison

Pets and Mold: The Hidden Poison

Many articles are written about the danger that mold, especially toxic black mold, creates for humans. However, the topic of pets affected by mold is not as popular. Our pets are members of the family like any other, and ensuring their health and safety is just as important as providing our own. Should you not see or feel signs of mold exposure in yourself, keep an eye on your animals as well. Animals may have allergic reactions to molds that you or other household residents are not affected by, simply due to individualized immune responses.

Pets tend to sniff (inhalation through the nostrils), travel, and lick around the home. If mold is present on the house or food, a pet can quickly become ill from the exposure. Depending on the species of mold and the amount of exposure time, the symptoms can range from minor to severe. If a limited exposure has occurred, your pet may sneeze or cough, while prolonged exposure time may trigger neurological systems or become fatal. If your pet has been exposed to mold, the reaction can vary depending on if the response is a result of allergens, inhalation, or ingestion.

Allergenic Reactions

If your pet is allergic to mold, the symptoms may be minimal. Some animals show signs of excessive scratching, chewing, biting, or licking affected areas. Due to this extensive behavior, sores may develop on the skin, and fur loss can happen.

Inhalation Reactions

When your animal inhales, mold respiratory distress may occur. Respiratory distress may mean, breathing may take more effort or seems to be occurring faster than average. Other signs of mold inhalation may include nasal discharge, coughing, wheezing, sneezing, and fatigue. Bleeding from the mouth or nose has also been a known symptom in animals in severe cases.

Ingestion Reactions

Ingestion of mold can be from contaminated food they eat, or areas of the home they have licked that are infected with mold growth. Ingesting mold has been known to cause gastrointestinal tract disruptions such as vomiting, loss of appetite, and changes in the stool. Severe cases have also reported blood in stools.

Depending on the type and exposure time of mold, your pet may exhibit serious health concerns. Mycotoxins, toxic spores released by certain toxic molds, are known to disrupt the nervous system. Tremors and seizures, along with odd behavior, may occur in your pets. If you believe your pet has been exposed to mold, it is imperative to get a veterinary’s help as soon as possible. Delaying treatment can lead to damage of the liver, kidneys, bones, brain, and spinal cord.


Not only home structure prevention but also household prevention is vital for you and your animals’ health. Relocating your pet temporarily with a friend maybe a savvy choice when suspecting or remediating mold. Relocation can ensure your pet doesn’t investigate an area that is infested and cause health concerns. Storing your pet’s food in an air-tight container will discourage mold growth on the food. Weekly washing of chew toys, food, and water bowls will also deter mold build-up. Pet beds should be regularly washed and completely dry before use. Plush toys, leashes, and other fabric pet supplies should also be routinely cleaned and dried.

If you are unsure if your home has mold, or suspect there may be an affected area, call us at Mold Inspectors Of Florida to get a detailed inspection. With topical swabs and air quality testing equipment, our technicians check thoroughly for mold. With specialized equipment to test within walls, as well as lab analysis for a detailed report on findings, rest assured you will have all the knowledge of what’s growing within your southwest Florida home.

Dangerous Common Household Molds

Dangerous Common Household Molds

Dangerous Common Household Molds

There are thousands of mold species in the fungal world. With species, sub-species, and a single fungi, it’s no wonder that the word “mold” has become a scary topic around the world. From expensive home remodels and remediations to painful illnesses, molds have become a hot topic in the homeowner circle. When a homeowner hires a mold inspector, there are endless possibilities for the findings of mold in a home and its structures. Having a basic knowledge of some of the common household mold species can give homeowners a sense of understanding they need to become proactive and preventative on household mold.


Allergenic in classification, this mold also has the capability of becoming toxic depending on the species of this strain. Bringing in a professional mold inspector for analysis is the only way to accurately determine the species of molds present. While many describe this mold as long and flask-shaped spores, the colors vary by species, and this mold has more than 185 species in its genus line.  There are general minor risks associated with the inhalation and exposure to Aspergillus, as it is incredibly common indoors. However, certain species can create severe allergic reactions depending on the individual’s immune response. Severe reactions can include respiratory infections and inflamed lungs. There are particular species of this genus that can produce deadly carcinogen aflatoxins, a toxic compound formed by molds that are known to cause liver damage and cancers.


Alternaria is a known allergenic mold with a velvety dark green or brown appearance. Some homeowners describe this appearance as green or brown hairs growing. This fungus is one of the most common forms of household mold and found in the shower, bathtub, and below household sinks. Alternaria is usually quick to resolve if detected early, but can also commonly signify water damage. Depending on the location that the homeowner finds this mold, bringing in a professional mold inspector to take a more in-depth look may be the savvy choice. Alternaria is known to worsen or mimic the symptoms of asthma and respiratory problems.


Cladosporium appears in a suede-like texture as an olive-green or sometimes brown colored mold. This specific household mold is an allergenic classification that is found in both cold and warm areas of a home. Should the environment be moist from condensation, leaks, humidity, or water damage, Cladosporium can grow. Carpet and fabrics, along with wood floors and cabinetry, have all been known to fall victim to this fungus. Cladosporium is known to specifically cause attack on the human respiratory system.


Trichoderma is a complicated, household mold. While this mold is classified as an allergenic, most Trichoderma molds are non-pathogenic (does not produce illnesses). However, various strains of Trichoderma are pathogenic and can produce mycotoxins, which cause sinusitis, allergic reactions, and more. This common species grows within wet fabrics such as carpet and upholstery. Trichoderma is also commonly found within moist condensation areas of the home, such as behind wallpaper, within air conditioning filters, and HVAC ducts. With five different sub-species of Trichoderma, should you suspect mold in your home, a professional inspection and analysis is required to determine the health risk to the household residents.


Ulocladium typically appears black. Homeowners often find this species of mold in kitchens, basements, and near windows. The common areas Ulocladium is found are known for extreme water damage and high levels of condensation.  This fungus is most common after severe water damage such as flooding or tropical storms and can appear both indoors and outdoors. Ulocladium slowly growing in the walls and floors after an event of water damage can cause severe allergenic reactions. Most commonly, Ulocladium begins mimicking the symptoms of hay fever and triggering asthmatic reactions.
