How Does Mold Appear

Mold is a fungus with a microscopic structure. You can see it with a naked eye — everyone knows what spoiled food looks like. However, if you look at the mold under a microscope, you will see that it consists of threads with a bunch of balls around them — spores that it reproduces with.

Mold can be found everywhere – in soil, wood, dust fibers, and even in synthetic fabrics. Most often, mold appears in warm, humid places where organic substances serve it as a nutrient. Therefore, wallpaper glue, dust containing tiny organic particles are all good food for mold. However, the fungus is not always immediately visible, and dark spots signal that the fungus has been successfully developing in this place for a long time.

Bedrooms, bathrooms, and kitchens are high-risk areas. This is where the first signs of mold appear on the walls most often. Due to the specifics of their use and insufficient ventilation, there is often increased humidity in these rooms.

Main causes of mold:

  • high humidity and warm temperature;
  • insufficient or faulty ventilation, hermetically sealed PVC windows and poor air circulation;
  • the furniture fits the walls too snugly;
  • uneven heating or freezing of the room;
  • leaks;
  • premises above damp basements;
  • use of low-quality construction materials during repairs and non-compliance with construction technologies;
  • a combination of all or any of these factors.

Why is Fungus in Your Apartment Dangerous?

Fungus in a residential area has an extremely negative impact on the residents’ body and health. Fungi are known to reproduce by spores, that is, by releasing spores into the environment. Thousands of these microscopic particles can float in the room and chances are that they can get into your body and cause various respiratory diseases (rhinitis, pharyngitis, asthma, allergies).

In addition, your immune system weakens because of continuous and close contact with the fungus. Your personal items will have an ever-present smell of dampness, causing them to lose their initial appearance and durability, and eventually, they will rot altogether. This applies not to fabrics only, but wood and plastic, too.

Your health should always be your priority. Therefore, it is best to get rid of the mold as it can pose health problems. For your ease, we’ve listed some of the most common health issues that are caused by mold.

Breathing Issues

Spores, cells, and various unstable compounds can invade the air when mold begins to grow. The dampness caused by indoor mold breaks down substances, which in turn leads to a high level of dust and particles in the air.

Furthermore, these particles can act as irritants and allergens that disturb the lungs, nose, and throat. People who suffer from breathing problems are more vulnerable.

The symptoms of mold allergies are similar to those of other allergies. Airborne substances produced due to the mold, affect the upper respiratory tract of an individual. As a result, the person affected might suffer symptoms that include:

  • Runny and itchy nose
  • Watery eyes
  • Sore and itchy throat
  • Sneezing

As dust levels rise, the dust mites multiply, too. Consequently, this can be quite dangerous as it can often trigger allergic reactions in some people.


Serious health problems can also be caused by specific types of molds, such as Aspergillus. Usually, people do not get sick after breathing in the spores of this fungus. However, it can cause a severe reaction in individuals with weak immune systems or lung diseases. There are various types of aspergillosis, and each type may cause different symptoms.

How Do I Get Rid of Mold?

To get rid of mold in your home once and for all, you need to take a serious and comprehensive approach.

to get rid of mold

First, you need to eliminate the source of humidity and poor ventilation in the room where the mold is found. Air purifiers can help you there. Modern air purifying systems allow maintaining an optimal favorable climate in any room, even the one with high humidity. Only after normalizing the room atmosphere can you be sure that the mold will no longer appear.

The second step of this comprehensive approach to fighting mold presupposes mechanical cleaning of infected room areas. You must eliminate all mold foci and perform preventive treatment. There are two ways to do this: chemical and natural (home) agents.

Chemical agents for eliminating mold are the easiest and most effective way to get rid of it. Today, you can buy them in almost any construction and hardware store along with special antiseptics to be applied to the cleaned areas to prevent fungus in the future. If you are not allergic to chemical agents, this is the best way to treat the infected surface.

If you do not want to use chemicals for some reason, there are several natural methods. Obviously, they are less effective yet they can still help. Traditional means are best used as a preventive measure:

  • Baking soda – The most famous natural cleaner. It attacks mold effectively and without any damage to your health. To use this method, you need to prepare a solution with 3 teaspoons of baking soda per one glass of water. Spray the surface with this solution, let it sit for 10 to 20 minutes, and then wipe it with a damp cloth. Try not to wipe it too thoroughly, so that soda particles are not washed off completely.
  • Vinegar – Table vinegar is good for cleaning surfaces from mold. Apply it using the sprayer and let it sit for an hour. Then wipe the surface with a damp cloth. A huge disadvantage of vinegar is its strong unpleasant smell, which is, moreover, harmful to your health. Therefore, it is best to treat the surface with your windows open and wearing a respirator.  Ventilate the room thoroughly after the procedure is over.
  • Hydrogen peroxide – Another traditional remedy for getting rid of mold is a hydrogen peroxide solution. It is an excellent antiseptic, it is non-toxic, and does not have an unpleasant smell. You will need a 3% solution for this procedure. The only drawback here is that hydrogen peroxide has bleaching properties, so it is better to avoid using it for cleaning colored fabrics or wallpapers.
