This means that people with this type of health problem will feel the effects of black mold even worse than other persons. Anyway, it’s always best to get rid of this plague. Then to way for it to ruin one’s health.

What Are the Symptoms of Black Mold Exposure?

As stated above, black mold can affect the health of human beings. And those who have an immune disease will suffer the most. Here readers can find some of the symptoms of having this type of spore at home. Most of them are quite similar to those of the flu or a cold.

Other types of most serious symptoms include fever and nausea. As readers can see, it can make residents feel very uncomfortable and sick.

Where Do Molds Grow: Identifying Spores at Home

It can be tricky to properly name this type of toxic growth because its appearance can vary. Besides the color black, it can take on a yellow, green, white, or red tone. The spores this guide is referring to are the dangerous and potentially deadly mycotoxins that can affect any household. Belonging to the Stachybotrys family, it’s more common in humid areas. If an individual spots a dark, unfamiliar substance indoors, it’s best to contact a professional. In the meantime, here’s where and what to look out for to protect family health.

How to Get Rid of Black Mold

While eradicating all molds from home is virtually impossible, the following tips can help with testing for Stachybotrys fungi and how to ensure its removal.

Black Mold Prevention

Limit Moisture Exposure

One of the easiest things that individuals can do is to keep moisture levels as low as possible. Molds don’t take too well to dry air, so maintain good circulation throughout all the rooms in the house.

Remove as Much as Possible

Depending on where the infestation is, there might be tainted objects or carpeting. The best bet is to remove these things from the area. Most of the time, the cost of replacing a rug or drywall is lower than a remediation treatment.

Stifle Indoor Growth

Sometimes spores reach outdoor items first, so be sure to check any furniture or porous objects before bringing them indoors. When in doubt, keep it out. This is particularly important when storing wooden patio chairs and tables for the winter.

Tackle it With Products

When it comes to cleaning black mold, not just any spray will do. Fortunately, there are products specifically designed to tackle the mycotoxins in several types of mold. Consider a preventative cleaner for the bathrooms, kitchen, and basement.

Protect Cold Surfaces

This tip is for the basement in particular. Insulation is crucial, and yet lots of homeowners aren’t properly protecting their concrete floors. Something with a vapor barrier, such as plywood sub-flooring, can reduce moisture levels and keep moldy invaders away.

Heating & Cooling Expert

Spores in the home are nothing to play around with, so it may be best to seek guidance from a professional contractor. They can survey the property and point out any areas that are prone to spore growth.

Keep the Humidity Levels Low

A more tropical climate holds a greater likelihood of inviting fungi in. To combat this issue, use a dehumidifier to keep humidity levels at 60% or lower. In warmer weather, an air conditioner can help, too.

Warm Up the House During Winter

During the colder months, condensation can appear on windows. Therefore, even though there is less moisture in the air, it is building up and resting on the glass in the house. Keep an eye out for this and strike a perfectly balanced temperature.

Get the Air Flowing

Turn on some fans and open the doors between rooms to increase air circulation throughout the house. This will encourage warmer air to hit the colder surfaces, preventing spore growth.

Repair Leaks & Drips

Something like a leaky faucet can lead to excess moisture, creating the ideal environment for molds. Be sure to fix these inconveniences and regularly check on appliances to make sure there isn’t any water seepage

In the Kitchen & Basement

These two rooms are highly susceptible to fungal growth. Due to the number of appliances, as well as the presence of water, homeowners need to be extra diligent in these spaces.

In the Kitchen Basement

Circulate the Air With Fans

Cooking over the stove can cause a lot of moisture build-up. To remedy this, make use of the exhaust fan and funnel that warm, wet air to another portion of the house, or ideally, outside.

Do a Water Check

Make a routine of looking for leaks, seepage, drips, and puddles around the sink and other kitchen appliances. An accumulation of water will create the preferred breeding conditions for mold.

Don’t Neglect the Refrigerator

This appliance is prone to leaks, so be sure to check the drip pans and basics for water build-up regularly. If necessary, empty the tubs and give them a good washing before replacing them.

Stock the Crawl Space

It’s a bit inconvenient, but check out the basement’s crawl space for any spots where moisture and dirt can come in from the ground. Cover any places that you found with plastic to keep the area dry.

Remember to Ventilate

Crawl spaces also need some ventilation, so consider blowing a fan in there from time to time. It might even be necessary to install some vents on the outside wall.


Concrete floors are rarely prepared for prevention, so consider sprucing up the place with some paint or area rugs. This is a much better alternative to wall-to-wall carpeting, which can harbor pockets of water and heat.

Get a Professional’s Opinion

This lethal mold is nothing to play around with, so bring in an expert who can check the basement and kitchen floors. They can also look at other areas of the house and point out risk factors while offering professional advice.

Get Into the Gutters

Moving to the outside of the home, check that the gutters are working properly. Since they deal with a lot of excess water and damp leaves, they’re a good spot for spores to settle.

Around the Washer & Dryer

The laundry room is another area that homeowners can’t neglect. Washers and dryers are large appliances, and their vents and basins are great spots for spores to settle.

Around the Washer Dryer

1. Redirect the Dryer Vent

The clothes dryer should ideally vent to the outside to avoid excess moisture. All of that wet, warm air can end up making the laundry room or basement very humid, so proper circulate is a must.

2. Keep Things Clear

Moreover, make sure the vents are cleaned and free of obstructions. This includes things like lint, but also look for any holes that warm air can escape out of.

3. Watch Where Damp Clothes Go

Don’t just dump damp shirts and pants in a laundry basket and call it a day. The excess moisture will add up and invite toxins to start breeding.

The Bathroom & Beyond

Hot, steamy showers may feel great after a long day of work, but they can also invite the growth of various molds. Here is a guide to fighting off that invasion.

The Bathroom Beyond

Hit the (exhaust) Fan

Circulating the air is especially important in the bathroom, especially if there aren’t any windows in it. Hopefully, the room has an exhaust fan that can whirl the moisture into another part of the house.

Lay Down a Rug

Another way to combat that warm, tropical air is by putting an area rug in the room. It can help dissipate the moisture hanging around, as well as add style to this space.

Do a Leak Check

Homeowners should make it their duty to check the shower, tub, sink, and toilet for leakage or seepage. Spotting the issue early means they can remedy it and prevent further damage.

Crack Open a Window (if possible)

It helps tremendously to open a window (even just a bit) when taking a hot shower. All of that humidity and moisture needs somewhere to go, and the best choice is outside.

Don’t Leave Wet Towels Laying Around

Similar to the tip from the laundry room, those wet towels shouldn’t sit on the floor, a hanging rack, or a hamper. Toss them in the dryer to keep them from spreading a mildewy mess.

Black Mold Facts

Despite the seriousness of black mold, shockingly few people know what it is and why it’s so dangerous. Below are some staggering facts about this substance, including what it can do to the body and mind.

1. It Can Be Deadly

This is why it’s so important to know the symptoms of black mold. Prolonged exposure to the mycotoxin can lead to brain and organ damage and a compromised immune system.

2. It’s a Known Neurotoxin

Its spores can hook onto a person’s neurons, which can cause mental health issues like mood complications and brain tremors.

3. It Lowers Immunity

Breathing in spores can suppress the immune system, exposing victims to more diseases and diminishing their ability to fight off the toxins.

4. It Contributes to a Variety of Symptoms

It’s not just neurological problems that signify exposure poisoning. Other telltale signs include breathing issues, eye irritation, sneezing, fever, and headaches.

6. Expectant Mothers Are Especially At-Risk

Pregnant women need to be especially careful since exposure to this toxin can increase the chances of birth defects and miscarriage.

7. It’s Possible to Detect it Through Smell

Besides its distinct dark color, individuals can identify this fungus through its odor. It smells musty with a hint of mildew.

8. It Prefers a Tropical Environment

A warm, humid, and damp atmosphere is a paradise for all kinds of mold. That’s why people need to be extra careful about checking their bathrooms and kitchens.

9. The Damage Can Be Irreversible

Unfortunately, black mold exposure can end up weakening someone’s immune system permanently. Damages to the physical environment may also be irreversible.

10. It Technically Isn’t Toxic

It’s not the mold itself that’s the primary concern; it’s spores. They contain mycotoxins that can reach the brain and cause serious health issues.

11. Everyone is Surrounded By Mold

Fungi is everywhere, both inside and outside. Fortunately, there are lots of non-toxic and harmless ones, but black mold isn’t one of them.
