What Is Mold?

Mold is a type of multicellular fungi (1). Fungi are more common than you think — mushrooms and yeast are a type of fungus, and we eat them! So what gives mold such a bad rep?

It plays a vital role in nature — breaking down dead, organic matter. There’s a chance that you’re exposed to mold every day, but in small amounts, it’s pretty harmless.

Mold thrives in moisture zones. They reproduce through minute spores that travel through the air (2). Once they land on a wet surface, it takes them only a few days to start growing into the clusters that are visible to the naked eye.

Most homes have an endless supply of moist surfaces for mold to flourish in — the most common being bathrooms. Since a lot of bathrooms don’t have windows for damp air to escape sufficiently, it can become a massive breeding ground for mold.

It’s also more likely to form on wood and the insulation in your walls than on bricks and cement. Many American homes tend to face a mold epidemic at some point.

A severe infestation can cause permanent damage to your home, eating away at the drywall, floorboards or carpets. Even when the mold dies or is removed, it leaves behind stains.

The Effects of Mold on Your Health

Exposure to mold can result in an array of health complications (3). Even the healthiest person can develop allergic symptoms to mold, including:

  • Stuffed sinuses.
  • Irritated or watery eyes.
  • Throat irritation or soreness.
  • Coughing.
  • Skin irritation.
  • Asthma.

In some cases, prolonged exposure to toxic mold can cause serious illness. It can also worsen symptoms in people with weak immune systems or chronic illnesses. Some of these health problems include:

  • Bone marrow disease.
  • Heart conditions.
  • Neurotoxicity (4).
  • Lung infections in those with lung diseases.
  • Damage to the liver and kidneys (source).

Types of Mold in Your Home

There are 12 types of mold that tend to grow in homes (5). Let’s have a look at some of the most common and dangerous ones:

1. Alternaria

This is the most common type of allergenic mold. You can identify it by its dark green or brown “hair.” This species easily appears after water damage.

It spreads very quickly so it’s essential to treat it as soon as it’s spotted, or it could take over a home. If you experience an allergic reaction or asthmatic symptoms, check for this mold and remediate it immediately.

2. Acremonium

Acremonium is a toxigenic mold and one of the most dangerous types to have in your home. It can lead to bone marrow disease among other immune system and organ diseases (6).

It has a fine, powdery texture and is orange, grey, pink or white in color. You’ll find them in humidifiers, cooling coils, window sills or drain pans. If you spot this mold, it might be best to have it professionally removed as it’s so hazardous.

3. Cladosporium

This species grows on objects and surfaces that we’re constantly in touch with. The spores thrive in both cold and warm conditions and will make a home on moist or damp carpets, clothing and upholstery.

It’s an allergenic mold type, which is not quite the most dangerous, but it can still be difficult to deal with. We don’t recommend touching it upon discovery since it can cause an allergic skin or throat reaction even in someone without allergy issues (7). You can identify it by its formation of brown, green or black spots.

4. Stachybotrys

Stachybotrys is also known as “black mold.” It’s toxigenic but can also cause allergic reactions. Easily distinguishable from other mold species by its slimy texture, this one ranges from forest green to black in color.

You’ll see this type of mold on wood, cardboard, paper or wicker. If the walls of your house are composed of wood or if you have wallpaper, you might be at risk for Stachybotrys.

5. Mildew

Although not classified as mold, mildew is a type of surface fungi that can be identified by its grey or white patches. It tends to grow on surfaces like walls, bathroom corners and cupboards.

Mildew is the least dangerous type of fungi you’ll encounter in your home, and can easily be treated. However, this doesn’t mean you should let it grow wild — it can still trigger allergic symptoms.

Choosing the Best Mold Remover

Although a lot of mold removers are similar and provide matching results, there are some factors you might want to consider before buying one:

Surface Type

Check the specs or the label of the mold remover to ensure that it will be suitable for the type of surface you want to clean.

A versatile mold remover is always a good bet. This will save you money from having to buy separate products, and is just all-around convenient.

Potent Chemicals

Strong chemicals can end up causing damage to the surface you’re cleaning. So when buying a mold remover, watch out for bleach. It’s an effective cleaner, but can be dangerous if not used with caution (8).

Instead, keep an eye out for non-corrosive and non-abrasive products — they’re gentler.

Surface Area

Take note of the surface area that the mold is growing on. This will help you calculate how much product you’ll need. If the affected area is larger than 10 square meters, it’s best to have it professionally remediated.

Value for Money

Some brands offer bulk deals where you end up paying less for more. This can include one-gallon bottles or multi-pack offers.

A mold remover concentrate is a good way to get value for money. It needs to be diluted, and therefore produces a lot more product than you initially bought.


Let’s face it, a spray bottle is a lot more convenient. It’s also safer than pouring out the product and risking touching it.

Some products are even formulated to be sprayed on the affected area without the need for rinsing or scrubbing. This can make your life a whole lot easier.

How to Treat and Prevent Mold

We hate to break it to you, but everyone has mold in their home. It’s one of the most natural occurrences, and there’s no way to get rid of every single spore. However, there are some measures you can take to prevent mold reproduction from becoming problematic:

1. Identify the Problem

Start by inspecting any damp-prone areas in your house, including bathrooms, kitchens, basements, laundry rooms and crawl spaces. This can also be a great way to discover any leakage you didn’t know you had.

Remember to keep an eye on things that might not seem as significant. Things such as a spill on the carpet or laundry that was left in the machine by accident can be problematic.

2. Reduce Moisture

Mold can’t grow without moisture. Naturally, this means that if you reduce the moisture in your home, you’ll reduce the reproduction process of spores. Ways to reduce in-home moisture include:

  • Leaky pipes and seepage into the house from rainfall needs to be dried within 24 hours.
  • Regularly clean and repair gutters.
  • Remove carpets, furniture, bedding or clothing that has sustained any type of water damage.
  • Install a hood vent above the stove to evacuate and filter steam.
  • Don’t leave wet objects lying around the house — for example, hang swimming towels outside to dry.
  • Dry the walls and floors after taking a shower or a bath.
  • Keep indoor humidity between 30 and 50 percent.
  • When renovating or building a new house, opt for mold-resistant drywall and mold-resistant paint.

3. Plants

Indoor plants help keep the air clean and fresh by reducing pollutants (9). Nonetheless, the moist soil attracts mold. In a natural setting, this would be healthy, but indoors, the spores can easily spread throughout your house.

But, don’t get rid of your plants. Instead, add Taheebo tea to the water you feed them. The oil of the Taheebo tree contains powerful antibacterial and antifungal properties, strong enough to withstand mold growth in forests (10).

These properties will be absorbed through the soil and the plant, warding off a large portion of mold spores.

4. Mold Removers

A good mold remover will break down the clusters and all you’ll have to do is scrub or even just wipe it away. Most contain various antibacterial substances that not only eradicate growth, but clean the surface overall. It also contains ingredients that will remove stains caused by the mold.

Some are specifically formulated for tile surfaces, wood or fabric, and others are suitable for various surfaces. You can even use them regularly for general cleaning in order to prevent a mold breakout.

5. Safety

Before you dive right into cleaning, there are some precautions you need to take.

Getting up close and personal with mold can prove dangerous, even if you’re not touching it. Spores travel through the air and become denser around their colonies, increasing your likelihood of breathing it in.

Follow these steps if you’re about to come into contact with mold:

  • Wear old, long-sleeved clothes and shoes you can throw away once you’re done.
  • Cover your face with a surgical face mask, or in the case of a more severe infestation, invest in a respirator. This will prevent you from inhaling spores as well as potentially potent chemicals in the mold remover.
  • Wear goggles that fit comfortably.
  • Rubber gloves are ideal because they won’t allow moisture to seep through and touch your skin.
  • Wear a medical hair cap or a beanie you’re willing to get rid of and ensure it covers all of your hair.
  • Keep the windows open.
  • Cover the AC and ducts before you start cleaning.

If the mold accumulated on fabric, such as clothes, carpet or furniture, it’s best to throw it out. We know this can be an unfortunate loss, but mold is near impossible to fully get out of these materials, increasing the risk of spreading. Double-bag it and ensure it’s tightly sealed before disposing of it.

Call in the Big Guns

A good mold remover will come in handy for treating an infestation ASAP. But there are some things you might want to consider before purchasing one.

Take into account the affected surface type and area. This will help you determine what kind of formula you’ll need and how much of it. A spray nozzle will certainly ease the process of remediation, and always keep an eye out for bulk deals to save some cash.

As much as the best mold removers can improve the health of your home, the product itself could be toxic to your health or damage your home. If that’s a factor you’re concerned about, opt for toxin-free, non-corrosive and eco-friendly mold removers.

In with the mold remover, out with the mold!
