Common Household Items That Are Filled With Bacteria

It’s no secret that bacteria are everywhere. There are more bacterial cells in your body than human cells! But did you know that some of the most common household items contain tons of bacteria? From your kitchen sponge to your toothbrush, these items can be breeding grounds for bacteria. This blog post will discuss some of the most common household items that are filled with bacteria and what you can do to keep them clean!

Dish Sponge

Your kitchen sponge is one of the dirtiest items in your home! One study found that dish sponges are teeming with bacteria. 74% of dish sponges and rags tested positive for coliform bacteria, which can cause diarrhea, cramping, and vomiting. Eek! So how can you keep your sponge bacteria-free? The best way is to clean it regularly. You can do this by boiling your sponge for one minute or microwaving it for two minutes.

You should also replace your sponge every few weeks. Another option is to use a dish brush instead of a sponge. Dish brushes have bristles that can reach into nooks and crannies, making them great for scrubbing dishes clean. Plus, they’re easier to clean than sponges! Rinse your brush with hot water after each use and let it air dry.


It’s not uncommon for a toothbrush to be full of bacteria. About 100 million bacteria live on a toothbrush at any given time. While most of these bacteria are harmless, some can cause infection or other problems. To keep your toothbrush clean, it’s important to practice good hygiene. Be sure to rinse it thoroughly after each use and allow it to air dry. You may also want to consider using a natural disinfectant every few weeks. Even if you clean your toothbrush regularly, it’s a good idea to replace it every three to four months. This will help ensure that you’re not re-infecting your mouth with bacteria.


While a loofah can be a helpful tool in your shower to scrub away dead skin cells, it can also contain a lot of bacteria. If you don’t clean your loofah regularly, you’re just spreading that bacteria around your body. Loofahs house so many different bacteria because they are a moist and dark environment, which is the perfect place for bacteria to grow. If you want to avoid a bacteria-ridden loofah, make sure to clean it after each use with soap and water and allow it to dry completely. You should also replace your loofah every few weeks. One easy way to clean it is to put it in your dishwasher on the hottest setting.

Bath Towels

The warm and moist environment is the perfect place for bacteria to thrive. Your bath towel is no exception and is probably full of bacteria, especially if you are someone who uses it more than once before washing it. You can do a few things to keep your bath towels bacteria-free. First, make sure to wash them in hot water with antibacterial soap after each use. You should also avoid sharing your towel with anyone else to reduce the risk of cross-contamination. Finally, make sure to dry your towel after each use entirely, so it doesn’t become a breeding ground for bacteria.

Pet Toys


If you have a pet, you know that they love to play with their toys. However, you may not know that those toys can be filled with bacteria. When your dog or cat plays with their toys, they transfer bacteria from their mouths to the toy. This can be a problem, especially if you have young children who like to play with the same toys as your pet. It is important to wash them regularly to keep your pet’s toys clean and bacteria-free.

You can either wash them in the washing machine or by hand. Just make sure to use hot water and soap. Another method you can use is to soak the toys in a bleach solution. Bleach will kill all the bacteria, and it will help keep your pet’s toys clean.

Toilet Brush


This one may seem rather obvious, but still good to mention just how much bacteria is on it! A toilet brush is easily one of the most bacteria-filled items in your home. These brushes can hold more than 100 times the amount of bacteria as a toilet bowl. The bristles can easily trap dirt and germs, which can be spread to other surfaces when you use the brush again. You should clean toilet brushes regularly, and it’s best to keep them in a closed container to prevent cross-contamination. Soak it in a bleach solution for about five minutes to clean a brush. Let it air dry completely before using it again.

Cutting Board

A cutting board is a kitchen essential, but it can also be a breeding ground for bacteria if you don’t clean it properly. Bacteria such as E. coli and Salmonella can live on a cutting board for several days, so it is important to clean it after each use. One way to clean a cutting board is to soak it in hot, soapy water for several minutes. You can also use a disinfectant cleaner or vinegar to kill any bacteria.

Just be sure to rinse the cutting board well with hot water after cleaning it. Keeping your cutting board dry is also important, as bacteria thrive in moist environments. If you are using a wooden cutting board, oil it regularly to keep it from cracking and warping. You can also use a plastic or glass cutting board, which is easier to clean and doesn’t require as much maintenance. Regardless of what type of cutting board you use, be sure to clean it after each use to prevent the spread of bacteria.


Remember, it is essential to be aware of the bacteria lurking in your household items. While some of these items, like dish sponges and toothbrushes, can easily be cleaned with hot water and soap, others may require a bit more effort. Be sure to disinfect cutting boards regularly, hang towels to dry after use, and replace your loofah every few months. By taking these simple precautions and all the others on this list, you can help reduce the number of bacteria in your home and keep yourself and your family healthy!
