Is That Stain Dangerous? Identifying and Dealing with Household Red Mould

Mysterious orange patches in the bathroom? Unexpected spots on clothing or furniture? You likely have red mould, friend.

With the right know-how, you can tackle it head-on and even keep it from making a comeback. This guide will arm you with practical tips on how to handle red mould like a pro. But first, let’s answer the question on your mind…

What is red mould?

Red mould isn’t just one specific type of mould. It’s more like a family of fungi that share a knack for showing off in shades of red. It’s not just for looks. It’s a result of the mould reacting to its environment. Things like humidity, light, or even its own internal processes can give it that signature reddish hue.

In terms of colour, red mould can range from a vibrant vermilion to reddish-brown, sometimes even blending with hues of orange or pink. This colour variation depends on the mould’s growth stage and the surface it inhabits.

Common species linked to red mould include Neurospora, often found on food; Aspergillus, which can appear on water-damaged areas like walls; and Fusarium, which thrives in soil and plants.

You can find it both indoors and outdoors.

Red mould identification signs

The easiest way to spot red mould is by its appearance. It often forms slimy or powdery patches on surfaces. The colour is usually shades of red, pink, or orange. A persistent musty odour is another tell-tale sign that mould might be present, even if it’s not yet visible.

The way you confirm that you are infested by this kind of fungi is with a mould testing kit. You can buy one at any hardware store. These are really easy to use. You either place a petri dish in the suspected area to collect airborne spores or swab a visible patch of mould. That’s it.

Once you’ve done that, you send the sample to a lab for analysis. The results will not only identify the mould type but also show you the severity of the situation.

Is red mould dangerous?

Yes, it can actually affect your health. That goes double if you’re sensitive to mould or have existing health issues. Here’s what you might experience:

While red mould exposure can affect anyone, these groups are at higher risk:

1. Children – With their still-developing immune systems, kids are more vulnerable to mould exposure;
2. Elderly individuals – As we age, our immune systems weaken. That’s why seniors are more susceptible to the effects of mould;
3. People with pre-existing conditions – Those managing asthma, allergies, or weakened immune systems face a higher risk of serious reactions to mould exposure.

Where does red mould grow?

Red mould loves to settle in spots where moisture, warmth, and organic materials come together. The most obvious place is the…

How to get rid of red mould

Let’s divide this part into two sections. One for removing the red mould and one for preventing it. Both parts are equally important.

Removal methods

Here’s a step-by-step guide on how to get rid of red mould. First, start with safety in mind! Wear gloves, goggles, and a dust mask. This will help you avoid direct contact with mould spores. Also, open windows or use fans to ventilate the area.

There’s also the matter of using the appropriate cleaning solution. There is no right one, as it depends on where the red mould is growing.

1. Ceilings and internal walls. Create a bleach solution. 1 part bleach to 3 parts water. Apply the mixture to the affected area with a sponge or cloth. Let it sit for 10-15 minutes. Afterwards, scrub gently. Rinse with clean water and dry thoroughly;
2. Fabrics (Mattresses, Clothes). Soak washable fabrics in a mixture of warm water and white vinegar. For mattresses, lightly spray with a vinegar solution. It should contain equal parts of vinegar and water. Let it sit for an hour, then blot with a clean cloth. Check that everything is thoroughly dried so no lingering moisture remains;
3. Bathrooms (showers, tiles, and grout). Use a white vinegar solution or a paste made with baking soda and water. Scrub grout with a toothbrush, rinse, and dry. If mould persists, a commercial mould cleaner can help;
4. Wood surfaces. Apply a diluted hydrogen peroxide solution to the wood. Use a soft brush to scrub the area and wipe clean;
5. External walls. For brick or concrete surfaces, you need a stronger mould remover or a pressure washer.

When to call the pros?

If the mould covers an area over 10 square feet or keeps returning despite your efforts. That’s when it’s time to bring in professionals. Mould remediation experts offer services like:

Prevention methods

Once you’ve learned how to get rid of red mould, the next step is to stop it from returning. Prevention is all about controlling moisture and keeping your home clean.

Humidity control techniques

Use a dehumidifier to maintain indoor humidity levels. They should be below 50%. Place the machine in moisture-prone areas like basements or bathrooms. Make sure you also install and regularly use ventilation systems in the kitchen and bathroom. This will reduce steam and condensation.

And of course, open windows or run exhaust fans during and after showers. This will keep moisture levels down.

Regular cleaning

Clean areas like showers, sinks, and windowsills regularly with mould-resistant cleaners or natural solutions like vinegar. Pay extra attention to bathrooms, as they’re a hotspot for red mould in showers and on ceilings.

Also, avoid leaving damp items like towels, clothes, or sponges sitting around, as these can quickly become breeding grounds for red mould.
