Is green mould dangerous? That’s a question that often stirs up concern among homeowners.


In fact, when it comes to maintaining a safe and healthy living environment, their #1 worry is… the presence of mould.


They have NO idea how serious it can be. But this is what separates those who live in ignorance from the well-informed homeowner. Yet if you don’t know about the potential dangers of green mould, you’ll never achieve peace of mind within your home environment.


The truth about green mould can be quite unsettling.

Unmasking the Green Mould


If you’ve ever encountered a patch of green mould, it’s crucial to know that this term doesn’t refer to one specific type.


Rather, ‘green mould’ is an umbrella term for various species of fungi with greenish-hued spores.


The three most common types of green mould are Cladosporium, Aspergillus and Penicillium – all notorious for their production of mycotoxins in certain conditions.


Fascinatingly enough these moulds can grow in diverse colours like blue or black depending on environmental factors such as temperature and humidity levels.


Decomposing Organic Matter: A Breeding Ground For Moulds


A key characteristic shared by these moulds is their love for decomposing organic matter; they’re nature’s recyclers.


Studies have shown how different species prefer different food sources.


For instance, while some are notorious spoilers of breads and fruits others tend towards damp household surfaces.


This diversity not only complicates the task at hand but also poses unique challenges when trying to prevent growth or remove existing infestations.


Now let’s delve into identifying signs of green mould presence within your living spaces.

Identifying Green Mould in Your Home


First step to tackling a mould issue is recognising it.


Green mould, though not a specific type of fungus, refers to various species that emit green-colored spores.


This can include types like Cladosporium or Aspergillus which may also appear blue or black under certain conditions.


Differentiating Between Green Mould and Algae


A common confusion arises between green mould and algae due their similar appearance.


However, they are fundamentally different entities with distinct characteristics and habitats.


  • Mould thrives on decomposing organic matter while algae form harmful algal blooms in water bodies when exposed to sunlight.
  • Mould emits mycotoxins causing health effects whereas algae mainly pose environmental threats.


When trying to identify green mould, it is suggested to look out for splotches of varying hues ranging from olive green to bright neon on household surfaces.


These could be signs of an underlying issue.


If you notice such patches particularly around wet areas – think bathrooms or basements – then you might have a growing concern at hand.


Whether it’s spoiled food items showing fuzzy growths or your walls developing suspicious stains after heavy rainfalls; these are all potential indicators.


Remember: early detection can prevent further spread saving both time & resources down the line.

The Health Risks Associated with Green Mould


Exposure to green mould can have significant health effects.


All moulds, including those of the olive-green hue, are known for their potential harm to human health.


A study by National Center for Biotechnology Information (NCBI) in the US, states that exposure to mould spores can lead to respiratory issues in susceptible individuals.

  • It’s dangerous particularly for people suffering from asthma or allergies as it may trigger severe attacks.

Mould Spore Inhalation: A Silent Threat


Inhalation of these tiny particles often goes unnoticed but steadily harms your lungs over time.


  • This especially becomes an issue when there are large mould infestations within closed spaces like homes or offices where air circulation might be limited.

Harmful Algal Blooms Vs Green Moulds


You might confuse green colored moulds with harmful algal blooms because of similar appearance; however they affect your health differently.


Mostly found in water bodies emit toxins affecting marine life while green moulds thrive on decomposing organic matter releasing mycotoxins causing allergic reactions.


Stay tuned. We will next delve into comparing dangers posed by different types of moulds.

Is Green Mould Dangerous?


The question “is green mould dangerous?” is a common concern for many homeowners.


In truth, exposure to any type of mould, including the green variety, can pose health risks.


While not everyone will experience symptoms when exposed to moulds like green mould, some individuals may suffer from respiratory issues or allergic reactions.


Dangers Associated with Green Mould Exposure


Moulds emit mycotoxins that can cause adverse effects on humans. Inhaling the toxins released by this fungus over a prolonged period can be especially detrimental.


If you’re susceptible due to factors such as allergies or asthma, living in a home infested by this fungus could lead to frequent bouts of coughing and sneezing; eye irritation; skin rashes; and even chronic conditions like sinusitis.


Comparing Green Mould with Black Mould


A comparison between black mould (often associated with ‘toxic’ varieties) and green colored mould reveals similar potential dangers.

Both types produce spores which have been linked with severe health problems when present at high levels indoors. Long-term exposure might contribute towards developing serious lung diseases.

Please remember – while certain species may be more toxic than others – no indoor mould growth should be considered safe.

Preventing Green Mould Growth


Maintaining a dry and clean environment is the key to preventing green mould growth.


This microscopic menace thrives in damp, humid conditions often found in basements, bathrooms, attics or laundry rooms.


The Importance of Moisture Control


To keep these spaces free from mould infestation requires effective moisture control strategies.


One suggestion is using dehumidifiers and air conditioners to maintain low humidity levels.


Cleaning Practices for Prevention


Besides controlling humidity, regular cleaning can also prevent the onset of this fungus on household surfaces.


  • Avoid letting wet clothes sit around as they provide an ideal breeding ground for moulds like Cladosporium or Aspergillus that grow green spores.
  • Ventilation plays a crucial role too; ensure your home has good airflow especially areas prone to becoming moist such as kitchens and bathrooms.


Stay tuned for our next section where we’ll delve into how homeowners can effectively remove smaller patches of green colored mould without expert assistance.

The Dangers of DIY Mould Removal


While it may be tempting to try tackling mould growth yourself using home remedies, this carries significant health risks that are rarely worth it.


Disturbing mould during improper DIY removal can stir up hazardous spores into the air you breathe. And if underlying moisture issues aren’t fully addressed, the mould will simply return again.


Who Should Avoid DIY Mould Removal


Certain vulnerable groups should never attempt DIY mould removal, including:


  • Infants and children
  • The elderly
  • Pregnant women
  • Those with respiratory conditions like asthma
  • People with weakened immune systems


Even for healthy adults, the dangers posed by mould spore inhalation make professional removal the wise choice in most cases.


When to Consider DIY Removal


The only scenario where DIY mould removal may be appropriate is for spot treating very small areas of surface mould growth (less than 10 square feet) using gentle, non-toxic methods.


However, it’s essential to wear protective gear like gloves, goggles and masks when doing so. Ensure the area is well-ventilated too.


For mould growth beyond minor surface spots, call in professional removal services for your health and safety.

Benefits of Professional Mould Removal


Hiring a professional mould remediation company offers many benefits:


  • Safe, effective mould elimination using specialised tools and containment techniques to minimise spore release
  • Thorough inspection and testing to identify all mould sources
  • Addressing root moisture problems to prevent recurrence
  • Protecting vulnerable family members from spore exposure during the process
  • Reduced risk of developing mould-related illnesses down the road


Don’t gamble with the dangers of mould. For anything beyond minor spots, partner with mould removal professionals for clean air and lasting peace of mind.
