Mould comes in various forms and in a surprising array of colours. While they might seem like a mere visual distinction, these colours can actually tell us a lot about the nature of the mould. In this article, we’re going to delve into the world of common house mould types, categorising them based on their colours. By recognising these different hues, you can equip yourself with the knowledge needed to identify and manage mould issues more effectively.
Green Mould
Green mould is one of the most common types of house mould you might encounter in your home. They thrive in areas that are consistently damp and humid. Your bathroom, for instance, can be a prime breeding ground for green mould. Even indoor potted plants can become a cozy home for green mould if they’re not getting adequate sunlight and air circulation.
Green mould includes Cladosporium, Aspergillus and Penicillium.
Black Mould
Black mould is notorious for its potential health risks and can be a real headache to deal with. They often take advantage of water-damaged spaces, making basements and areas with plumbing leaks their preferred habitats. If you spot black, slimy patches of bathroom mould, whether on the ceiling or walls, it’s a clear sign that you’re dealing with this troublesome mould.
One of the well-known black mould species is Stachybotrys chartarum. Other mould strains that can be present as black in colour are Aspergillus and Cladosporium. Found these mould types in your home? Here is what you should do.
White Mould
Unlike their attention-grabbing counterparts, white moulds tend to be more discreet. They prefer lurking in hidden corners and forgotten items, which makes them harder to detect. Dampness in basements or attics can provide the ideal conditions for white mould growth. You might find them on stored belongings or in less frequently visited rooms.
Aspergillus, Penicillium and Cladosporium are some types of house mould that can appear as white.
Brown Mould
Brown moulds have a particular affinity for organic materials like wood, paper and fabrics. These moulds are often found in areas with high humidity levels. If you have cardboard boxes stored in your basement or a wooden shelf in a damp room, keep an eye out for brown spots or patches. Brown mould includes Stemonitis, Cladosporium and Ulocladium.
Yellow Mould
Yellow mould tends to thrive in spaces with both humidity and light. Kitchens, especially those with poor ventilation, can be a haven for yellow mould growth. Imagine the damp corners near your sink or around windows – these are the areas where you might spot their yellowish presence. Penicillium, Aspergillus and Mucor are examples of this type of house mould.
Blue Mould
Blue moulds have a distinctive appearance, often presenting as powdery or fluffy textures. They can take up residence on various surfaces, but they seem to have a particular liking for fabrics and materials. If you’ve ever left a damp towel in a corner or forgotten a piece of clothing in a humid room, you might encounter this house mould. While not as commonly discussed as some other moulds, their presence can still contribute to a less-than-ideal living environment. A great example of this type is Penicillium.
Orange Mould
Orange moulds are a bit more unconventional but still worth noting. They often flourish in environments rich in iron, which can include areas around plumbing fixtures. Watch out for spots near pipes or faucets in your home, especially if there’s persistent moisture. Orange mould includes Acremonium, Fuligo septica and Trichia varia.
Allergenic vs Pathogenic vs Toxigenic Moulds
The effects of house mould on human health can vary significantly. Understanding the distinctions between allergenic, pathogenic and toxigenic moulds is crucial for assessing potential risks and taking appropriate actions, such as calling in professional mould removal services. Let’s break down these differences.
Allergenic Mould: The Common Irritants
Allergenic mould primarily triggers allergic reactions in susceptible individuals. These reactions can range from mild irritations to more severe symptoms. Common symptoms include sneezing, coughing, watery eyes and skin rashes. Cladosporium and Aspergillus are examples of allergenic moulds. While they can be bothersome for people with allergies or sensitivities, they generally pose less severe health risks compared to other types of mould.
Pathogenic Mould: The Health Concern
Pathogenic mould has the potential to cause infections, particularly in individuals with weakened immune systems or pre-existing health conditions. While healthy individuals might not be severely affected, those with compromised immunity can experience more significant health issues.
Aspergillus fumigatus is an example of a pathogenic house mould that can cause respiratory infections in susceptible individuals. While the risks are higher for immunocompromised individuals, it’s still important to address pathogenic moulds to maintain a safe living environment.
Toxigenic Mould: The Harmful Contaminants
Toxigenic moulds are the most concerning due to their ability to produce mycotoxins – harmful substances that can have serious health implications. These mycotoxins can be released into the air, potentially leading to respiratory problems, neurological symptoms and other health issues. Black mould is an example of toxigenic mould that can produce mycotoxins.
Knowing the differences between allergenic, pathogenic and toxigenic moulds is essential for safeguarding the well-being of your household. While allergenic moulds might cause discomfort for some, pathogenic and toxigenic moulds can pose more significant health risks, especially for vulnerable individuals.
Regular inspections, proper ventilation and addressing moisture issues promptly are critical steps in preventing mould growth and minimising potential health concerns. If you suspect that your home has mould issues, especially of the pathogenic or toxigenic variety, seeking professional assistance from the best mould remover in Melbourne is strongly recommended to ensure a safe living environment for you and your loved ones.
