A Guide to Black Mold

Black mold sounds just as menacing as it is. It releases lethal mycotoxin spores and can cause neurological breakdown, pulmonary decay, immune system degradation, skin irritation, and even death. Whether you’re working to prevent black mold from growing in your home or remediating an existing problem, here are facts you need to know to stay safe.

Black Mold Facts

1. Black mold is a neurotoxin.

The spores released by black mold attach your brain’s neurons—incapacitating your mental ability. The reaction to black mold can be tremors, mood swings, and other neurological shifts.

2. Black mold suppresses your immune system.

When you breathe in black mold spores, your immune system is weakened, so on top of being sick from the mold, you can also become more easily ill from germs.

3. Black mold can kill.

If you’re exposed for long enough, black mold spores can shut down your organs, incapacitate your immune system, and damage your brain—resulting in death.

4. Black mold endangers pregnant women.

Women who are pregnant can suffer birth defects, miscarriage, and infertility later on.

5. Black mold can harm anyone—including pets.

The young, sick, and elderly are most susceptible to black mold symptoms and damage, but all living things can be harmed by black mold.

6. Black mold has a smell.

The mold smells like mildew and must, so it’s detectable even when you can’t see it.

7. Mold grows in damp, humid, and warm locations.

All molds love this combination and thrive in it. That’s why your bathroom is a breeding ground for black mold and other types of mold.

8. You’ll suffer from a number of symptoms when exposed to black mold.

Symptoms of black mold exposure include fatigue, headaches, seizure, tremors, mood swings, confusion, fever, eye irritation, sneezing, rashes, coughing, bleeding of the lungs, and sometimes death.

9. Black mold isn’t actually toxic.

The mold itself isn’t poisonous—just the spores it emits.

10. Some damage is irreversible.

Depending on how long you live amongst black mold, you could suffer once it’s been remediated. Immune system weakening and sensitivity to mold can persist throughout your lifetime.

11. Mold is everywhere.

Mold spores are all around us all the time. Only some present major health hazards.

Before you fly off the handles, make sure the mold you’re seeing is, in fact, black mold. The easiest way to identify mold is to look at the color. Mold can be black, white, green, red, and orange. If your mold is any color other than black, it’s not black mold. Other molds can be treated with a bleach solution. However, if you’re unsure, you should call a professional rather than handle a potentially dangerous substance yourself.

Black Mold Prevention

Keeping mold out in the first place is your best plan of action. You can avoid paying a ton for mold remediation and endangering your health by doing the following:

1. Keep it dry.

Keeping your home dry is key to preventing mold from growing. Dehumidifiers in basements, ceiling fans in bathrooms, and good air flow can all improve your chances of keeping mold at bay.

2. Remove tainted material.

It’s imperative that you remove affected materials if you undergo mold remediation.

3. Keep it outside.

Never bring old wood or other porous objects in from the outdoors. Mold spores grow on everything and can go wild when brought indoors.

4. Use cleaning products.

You can use mold reducing sprays in your bathroom and damp locations. Endurance BioBarrier (Amazon) preventative mold spray is one product that discourages mold growth. It works on mildew too.

5. Get a dehumidifier.

Dehumidifiers suck moisture out of the air and prevent mold growth. The Frigidaire FAD504DWD Energy Star 50-pint Dehumidifier (Amazon) is the “#1 Best-Selling” dehumidifier on Amazon and will do the trick.

6. Keep water away from your house.

Water is key to mold growth. Don’t let your basement or home become flooded, and you’ll have waged half the battle on mold. You can do this by grading your yard to keep water flowing away from your house. You may also install downspouts that divert water from your home.

Mold Remediation

If mold creeps up on you or you buy a new house and find it hiding in the walls, don’t panic. You can have mold professionally remediated. While this can cost anywhere from $500–$10,000, you might be able to add a rider to your homeowner’s insurance policy to cover this event.

Mold remediation specialists use special ventilation masks and clothing for protection. You won’t have those products on-hand, and should avoid a DIY approach since it’s can be dangerous. In some states, it’s actually illegal (especially during a renovation) to handle the mold yourself. Inspectors will have to sign off on the remediation to ensure safety to the building’s occupants.

Black mold is an unwelcome and dangerous guest in your home, but it can be prevented and treated. You can learn more about prevention, mold control, and top water damage reducing products here.

    This is not grounded in science at all. For articles grounded in science and read articles about mold on the CDC, EPA, and OSHA websites. Not a blog with affliate marketing links to mold test kits on Amazon. Ever plant flowers in top soil? You just breathed in millions of mold spores. You’ll live. Control the moisture, clean it up, move on with life. The profiteering and scare tactics need to stop. Please cite credible references that irreversible brain damage and death can occur like you claim. *Credible* peer reviewed references.

    Phil you are so closed minded how can anyone think you have credibility at all. People are telling your their life experiences, something a TRUE scientist would jump on, but instead you attack them saying they have psychological problems. I’ve gotten pneumonia from black mold, verified by science and doctors…and it wasn’t pretty.
    Open your mind and learn a thing or two. If you close your mind you’ll never be any smarter than you are now…and well…

      Lisa – I’m a scientist and work off data not emotional heresay – and you’d not know science if it bit you on the butt. Share the diagnostic paperwork or shut up.

    We live in South Carolina and we have very selfish landlord and bad mold here in our house. We don’t have any windows open. We are scared to contact someone about it because we have all the symptoms.

    We are afraid that we will end up on the streets because our house is a mess and they will look at us as unfit for living in a house/apartment.

    TBH what do we need to do? How will the health department judge us based on how we clean our house? Will they come back at us because we are living in a messy house or will they look at our landlord because she has really bad black mold?
