Hidden Sources of Bacteria in Your Home

One of the many ways people improperly clean their houses is by only doing it when a room or region is obviously dirty. By simply glancing at a surface, you cannot see the germs in your house. In order to maintain regular cleaning and disinfection of certain areas, it is necessary to be aware of where the sources of bacteria are in your home.

Here are 20 common hidden places of bacteria in your home.

1. Computer Keyboard

Your keyboard has more bacteria than your toilet seat. Studies have shown that keyboards can harbor more than 200 times the amount of bacteria as a toilet seat.

This is because you are constantly touching their keyboards and then touching your face. The average person touches their face 16 times an hour, which means they’re transferring germs from their keyboard to their face constantly.

Meanwhile, there are holes or cracks in keyboards that provide the perfect environment for bacteria to grow. Sometimes you’re eating above your keyboard and crumbs fall in, but you cannot pull it out, or you forget to clean it. All of these factors add up to create a breeding ground for bacteria.

2. Mobile Phone

Mobile phones are full of bacteria because we take them everywhere with us, including the bathroom. We also put them on all sorts of surfaces, like restaurant tables and public transportation seats, in our laps, in our pockets, and in other places where they can pick up germs. All of these surfaces are covered in bacteria, which then gets transferred to our phone screens.

3. Keys

There are many reasons why keys may have bacteria. First, keys are often kept in places that are not very clean, such as pockets or purses. Bacteria can easily thrive in these environments. Secondly, keys are often handled by people who have not washed their hands thoroughly.

This means that bacteria can easily be transferred to the keys. Finally, keys are often made of materials that are not very resistant to bacteria, such as metal or plastic. This means that bacteria can easily colonize the surface of the keys.

4. Door Handles and Light Switches

One of the most frequently touched areas in your home is door handles and light switches. Every time you enter a room, you touch the doorknob or handle, and every time you leave, you again must touch it. You also constantly touch light switches throughout the day as you move about your house.

These areas can easily become covered in bacteria if they are not cleaned on a regular basis. Every time you touch a door handle or light switch, you leave behind microorganisms. If you don’t clean these areas, the bacteria will continue to build up.

5. Laundry

Laundry is another common source of bacteria in the home. This is because laundry hampers and baskets are often kept in moist, warm environments – both of which are ideal for bacteria to grow. 

In addition, dirty clothes that have come into contact with sweat, saliva, or other bodily fluids can also transfer bacteria to your laundry hamper. Once the clothes are in the hamper, it can be easy to forget about them until it’s time to do a load of laundry. This means that the bacteria have ample time to multiply.

6. Dish Towels

Dish towels are often used to dry hands, which can transfer bacteria to the towel. In addition, dish towels are often kept in moist, warm environments – both of which are ideal for bacteria to grow.

7. Makeup Brushes

Makeup brushes are easily forgotten about but they can be a major source of bacteria. Your makeup brushes are dirty as it blends makeup dust, residues, oils, and sweat from your face.

The residue, dust, oil, and sweat combinations from makeup form an ideal environment for bacteria to grow on dirty makeup brushes. Therefore, your face may be at risk of breakouts or an infection.

8. Microwave Handle

There may be yeast, mold, and coliform bacteria lurking on the surface of your microwave handle. The heat from cooking does not kill these bacteria, so it’s important to clean your microwave handle on a regular basis.

9. Children’s Toys

Your children may play with toys every day with their dirty hands, but you may not have time to wash toys every day. Food residues in your children’s hands can attract bacteria, and if the toys are not cleaned properly, these bacteria can transfer to your children’s hands and cause them to become ill.

Children’s toys are often contaminated with bacteria that can cause infections. The most common type of bacteria found on toys is Staphylococcus aureus (staph). Other types of bacteria, such as Pseudomonas aeruginosa and Escherichia coli (E. coli), can also be found on toys.

It is important to clean your child’s toys regularly to remove any bacteria that may be present. You can use a mild soap and water solution to clean the toys. You should also disinfect the toys using a bleach solution or another type of disinfectant.

Be sure to dry the toys completely before your child plays with them again.

10. Salt and Pepper Shakers

You may seldom clean Salt and pepper shakers, but these are common places where bacteria can grow. The salt and pepper shakers have many tiny holes that can trap bacteria. Kitchen is a hot and wet environment, which is perfect for bacteria to grow. If you don’t clean your salt and pepper shakers regularly, the bacteria can spread to your food and make you sick.

11. Kitchen Sponge

There are many reasons why kitchen sponges have bacteria. First, they are often used to clean up food and water spills, which can leave behind bacteria. Second, they are usually stored in a damp environment, which provides the perfect conditions for bacteria to grow. Finally, sponges are often used to scrub hard-to-reach places, like under the sink or in the crevices of countertops, which can also harbor bacteria.

12. Toothbrush Cups

Most people don’t think twice about where they store their toothbrush. However, if you’re not careful, your toothbrush cup can become a breeding ground for bacteria. Here’s why:

Toothbrush cups are often kept in moist environments, such as bathrooms. This provides the perfect conditions for bacteria to thrive. In addition, toothbrushes are often stored in close proximity to toilets. This increases the risk of contamination from fecal matter.

Toothbrush cups can also become contaminated from contact with other objects in the bathroom, such as toilet seats and towels. If these objects are not cleaned properly, they can transfer bacteria to the toothbrush cup.

The best way to prevent bacteria from contaminating your toothbrush cup is to keep it clean. Be sure to wash it with soap and water on a regular basis. You should also avoid storing it in moist or humid environments. If you must store it in a bathroom, make sure to keep it away from the toilet.

13. Video Game Controller

Most people don’t think about the bacteria that might be lurking on their video game controllers. However, studies have shown that these devices can harbor a variety of germs, including some that could potentially make you sick.

One study found that more than 75% of gaming consoles were contaminated with bacteria, including Staphylococcus and Pseudomonas. Another study found that video game controllers in public places like arcades were contaminated with germs that could cause skin infections, respiratory illnesses, and even food poisoning.

So why are video game controllers such a breeding ground for bacteria? Part of the reason is that they’re often handled by multiple people, including children who may not have good hygiene habits. In addition, controllers are often stored in places that are warm and humid, like on top of a television or in a entertainment center, which can create ideal conditions for bacteria to grow.

Fortunately, there are some simple steps you can take to help keep your controller clean and free of bacteria. First, make sure to wash your hands before and after playing. You can also use disinfecting wipes to clean your controller on a regular basis. Finally, don’t forget to dry it off completely after cleaning; bacteria thrive in moist environments.

14. Remote Control

Remote controls are one of the most commonly used devices in households today. They are used to operate a variety of different electronic devices, from televisions and DVD players to air conditioners and heaters. Although they are typically small and portable, remote controls can harbor a variety of different bacteria.

One of the main reasons why remote control has bacteria is because they are often handled with dirty hands. When people use remote control, they typically do not wash their hands beforehand. This means that any bacteria that is on their hands can be transferred to the remote control. In addition, remote controls are often kept in places where there is a lot of dust, such as on coffee tables or end tables. This dust can also contain bacteria, which can be transferred to the remote control when it is used.

Another reason is that they are often used in close proximity to other electronic devices. For example, people often use remote controls while watching television. The heat from the television can cause bacteria to grow on the remote control. In addition, the remote control can come into contact with other surfaces that may be contaminated with bacteria, such as doorknobs or countertops.

Also, the buttons on the remote control can trap dust, dirt, and bacteria.

15. Bathtub and Shower

Another often overlooked area in terms of cleaning is the bathtub and shower. Many people only focus on cleaning the toilet and sinks and forget about these two areas. 

However, if you don’t properly clean your shower, the bacteria can build up and eventually make you sick. One of the reasons your shower can become a breeding ground for bacteria is because of the humid and warm environment. 

In addition, soap scum and mold can easily build up in these areas if they are not cleaned on a regular basis. Be sure to clean your tub and shower regularly with a disinfectant cleaner to prevent the growth of bacteria.

Meanwhile, people often forget to clean their showerheads. Your showerhead can easily become covered in mold and mildew, which can then be sprayed onto you when you turn on the shower.

To prevent your shower from becoming a bacteria-ridden mess, make sure to clean it regularly. Scrub the tub and walls with soap and water and use a mildew remover on the showerhead.

16. Carpet

Your carpets are another area of your home that can easily become a breeding ground for bacteria. Carpets tend to hold onto dirt, dust, and other particles that can be full of bacteria. If you have pets, their hair and dander can also add to the amount of bacteria in your carpet.

Even if you vacuum regularly, your carpet can still harbor bacteria. The problem is that vacuuming only removes the surface dirt and dust. It does not remove the deep-seated dirt, dust mites, and other allergens that can be trapped in your carpet.

Over time, these allergens and dirt particles can become breeding grounds for bacteria. In order to remove the deep-seated dirt and allergens, you need to have your carpets professionally cleaned. Carpet cleaning will remove the dirt, dust mites, and other allergens that vacuum cleaners cannot reach.

17. Refrigerator Shelves

The shelves in our refrigerators can be home to all kinds of bacteria, from E. coli and salmonella to listeria and more.

There are a few reasons why refrigerator shelves are such a hot spot for bacteria. First, they’re often damp, which bacteria love. Second, food debris can easily build up on them, providing a perfect food source for bacteria to grow. Meanwhile, shelves are often hard to clean properly, so bacteria can linger even after you’ve wiped them down.

18. Kitchen Sink

Your kitchen sink is another area of your home that can easily become full of bacteria. There are many reasons why bacteria may be present on kitchen sinks.

  • often exposed to dirty water and debris, which can contain harmful bacteria.
  • often used for food preparation, which can contaminate the sink with bacteria.
  • often made of materials that provide a good environment for bacterial growth, such as porcelain or metal.

19. Toilet Seat

The toilet seat is one of the most commonly touched surfaces in your home. It is also an area that is constantly exposed to bacteria. Every time you flush the toilet, water droplets containing bacteria are sprayed into the air. These droplets can settle on the toilet seat and begin to grow.

In addition, if you don’t clean your toilet seat on a regular basis, urine and feces can build up. These substances are full of bacteria that can easily spread to the surface of the toilet seat. Be sure to clean your toilet seat with a disinfectant cleaner at least once a week.

20. Pet Bowl

Pets are lovely creatures that bring joy and companionship into our lives. However, they can also be a source of bacteria and other germs that can make us sick. One way these germs can spread is through pet bowls. Pet bowls can harbor all sorts of bacteria, including E. coli and salmonella, which can cause gastrointestinal illness in humans.

21. Cutting Board

Bacteria can easily transfer from one surface to another, and cutting boards are no exception. Bacteria can live on the surface of a cutting board and contaminate knives and other utensils that come into contact with it. Cutting boards can also become contaminated by contact with food that contains bacteria, such as raw meat or poultry.

There are two types of bacteria that are particularly dangerous: pathogenic bacteria and spoilage bacteria. Pathogenic bacteria can cause food poisoning, while spoilage bacteria can cause food to spoil.

The best way to prevent contamination of cutting boards is to clean them thoroughly after each use. Cutting boards should be washed with hot, soapy water and then disinfected with a solution of one part bleach to ten parts water.

In addition to cleaning and disinfecting cutting boards, it is also important to keep them dry. Bacteria thrive in moist environments, so it is important to make sure that cutting boards are not stored in a damp place.

If you are using a cutting board that is made of wood, it is important to treat it with a food-safe finish. This will help to protect the wood from moisture and bacteria.

22. Kitchen Faucet Handles

Most kitchen faucet handles are made of metal, which can be a breeding ground for bacteria. Kitchen faucet handles are also exposed to water, soap and other potential contaminants on a regular basis. Over time, these contaminants can build up on the surface of the handle, providing a food source for bacteria.

In addition, kitchen faucet handles are often touched with dirty hands, which can transfer bacteria to the handle.

23. Coffee Maker

There are many reasons why coffee makers can accumulate bacteria:

  • coffee makers are often located in areas that are not well ventilated. This can create an environment where bacteria can thrive.
  • not cleaned regularly.
  • the coffee maker’s filter can also be a breeding ground for bacteria.

All of these factors can contribute to the growth of bacteria in coffee makers. If you want to keep your coffee maker free of bacteria, it is important to clean the surface and filter regularly.

24. Kitchen Countertop

The kitchen countertop is one of the busiest places in the home. It’s where we prepare food, eat meals, and often use as a work space for other activities. Because it’s such a high-traffic area, it’s no surprise that bacteria can easily make their way onto the surface.

There are several reasons why bacteria love to hang out on countertops. First, food debris provides them with a source of nutrition. Second, the warm, moist environment is ideal for their growth. Finally, countertops are often made of porous materials that provide bacteria with a place to hide.

Foodborne illnesses, such as salmonella and E. coli, are commonly transmitted through contaminated countertops. In addition, countertops can also harbor dangerous bacteria that cause hospital-acquired infections, such as methicillin-resistant Staphylococcus aureus (MRSA).

25. Trash Cans

Trash cans are often overlooked when it comes to cleaning. However, they can easily become full of bacteria if they are not properly cleaned on a regular basis. Every time you throw something away, you are introducing more bacteria into the trash can.
