5 areas of the home where more bacteria accumulate

Identifying the areas of the home with the most bacteria will allow you to focus cleaning efforts to ensure that bacteria do not get out of control. Although, as we said, microorganisms are present on all surfaces in the house.

In fact, the Society for General Microbiology explains that there are about 10 times more bacterial cells than human cells in the human body. He also points out that there are some not very dangerous that only damage food, others that are useful for fermenting products and others that can cause serious diseases in animals and plants.

The point is that, since we do not know and cannot see them directly, it is best to keep all areas of the home clean, with special emphasis on those that by their nature can concentrate a greater amount of them.

Why is it important to control the growth of bacteria?

Although studies indicate that to achieve better control of the growth of bacteria it is necessary to know them in depth, at home we are not all scientists. But you don't have to be to understand that these microorganisms are responsible for some bad smells, especially in the kitchen and in the bathroom.

This in the best of cases, because we could also run into bacteria that end up becoming sources of diseases, such as Salmonella, Escherichia coli and Campylobacter, responsible for various types of foodborne infections.

The 5 areas of the home with the most bacteria

Calm! Do not be scared when reading the risks that can come from the bacteria that accumulate in your house. As we already mentioned, it will be enough for you to double the sanitation processes in the following areas of the home with more bacteria.

Microorganisms are guilty of some bad odors that appear on the surfaces of the home, clothing and the body itself.

1. The kitchen

According to research, the kitchen is one of the most susceptible places to the proliferation of microorganisms that adhere to different surfaces and utensils. Its origin is the food that we bring almost daily from the store, the natural process of proliferation that can be accounted for by the remains of food and moisture in the corners.

Now, among the kitchen elements in which bacteria are most found are the following:

  • Chopping boards.
  • Coffee makers.
  • Fridge.
  • Sink.
  • Sponges and brushes.

2. The bathroom

After the kitchen we find the bathroom, which is paradoxical if we think that this is where we are going to clean ourselves and get rid of dirt. However, it is for this reason that germs grow in this space and bacteria.

So this is the place where we have to put a lot of effort to clean. In addition, it is necessary to do it at least once a week. There are some elements that tend to be a greater focus than others, such is the case of toothbrushes.

A study indicates that to keep this daily use utensil away from the proliferation of bacteria that can make us sick, it is necessary to avoid leaving it in very humid spaces, near the toilet and with a case. Among the other elements to which we must pay attention we find the following:

  • Tap.
  • Toilet.
  • Discharge key.
  • Bar soaps.
  • Floor, joints and corners.

3. The laundry

Many people have a habit of depositing dirty clothes in the washing machine until they have completed a full load. This means that bacteria from outside can proliferate there, as well as those that come from sweat. We ourselves have created a focus of bacteria to pay attention to.

It is recommended that, to avoid further complications, whenever possible we use hot water to do the washing, with which we can get rid of these annoying microorganisms. Something similar happens when we let the clothes soak.

4. The study

The study is one of the areas of the home with the most bacteria on account of the utensils we use there. In this space we usually have the computer, keyboards and other electronic devices that we touch repeatedly.

In fact, an investigation determined that the surface of the mobile is a vehicle that carries pathogens due to the time we have it in our hands and the places we take it to. Something similar happens with keyboards, so be sure to wash your hands well and disinfect them often.

5. The rooms

Among the last areas of the home with more bacteria we find the rooms. There is our mattress, an object that allows us to rest every night in which mites, bacteria and viruses begin to accumulate that can spread throughout the room and home.

So clean the mattress and bed once a week, preferably with the vacuum cleaner. It includes the dressing room, where mites and bacteria that generate bad odors can also stay.

Utensils with more bacteria

In addition to the areas of the home with more bacteria too you should pay attention to other utensils that may be throughout the house. Among these we find the following:

  • Light switches.
  • Knobs and handles.
  • Pet toys.
  • Rugs
  • Makeup accessories.
  • Gym clothing and items.

Good habits for a clean home

To keep areas of the home with more bacteria clean it is necessary to have good hygiene practices, which include use of elements such as water, soap, bleach, vinegar and other disinfectants. Plus, clean at least once a week.

Objects are carriers of microorganisms, so it is advisable to do a general cleaning once a week.


In addition to cleaning, you must disinfect the home. In the specific case of bacteria and viruses, bad cleaning habits can spread them, so it is very convenient to take a few more minutes to disinfect. You can use a solution of water and bleach or alcohol greater than 70%.

Avoid the spotlights

The more you reduce the virus proliferation fence, the safer you will be. Clean utensils that come from the street, disinfect your shoes and clothes before entering the home.

Wash your hands regularly and sanitize the utensils you use the most often before leaving them on surfaces like the dining room, nightstands or bed.

Goodbye to the areas of the home with more bacteria

As you may have realized, bacteria can hide where you least expect it, but it is also easy to get rid of them and keep them at bay with constant cleaning. In the event that you feel unsure about the sanitation of your home, you can consult a specialized company.
