Your carpet may appear clean when you look at it with your naked eye. However, carpet has been known to accommodate numerous types of bacteria, dirt, and allergens that can negatively impact your health. This is even worse for carpets that are not cleaned and maintained regularly. A dirty carpet can be home to different types of allergens.

Dust Mites

These microscopic bugs depend on human and animal pet skin cells for survival. Dust mites thrive in humidity and places that do not have many interruptions. Therefore, when you do not clean your carpet, the dust mites live there without stress. They can survive on the base of your carpet because you do not touch it.

Therefore, a dirty carpet is a breeding ground for dust mites. Although dust mites do not cause disease, they can make someone who was not previously allergic to them to become allergic especially if there are huge levels of the mites and their wastes. Also, dust mites can make you develop nasal polyps growth within your nose.

Methicillin-Resistant Staphylococcus Aureus (MRSA)

When you walk on your carpet with shoes that you have used outdoors, then you are bringing in this bacteria into your home. This risk is notably higher for people living with athletes. When they come in and drop their unwashed gym bag on the carpet, walk with their shoes on the carpet or take off their shoes and step on the carpet with their dirty feet, these can bring in MRSA to your carpet. When you walk on the carpet, the fungi become airborne. These microbes might use small cuts within the foot to get into your body where they will cause various diseases and bacterial infections.


You have a high chance of getting this bacteria if you have a dirty carpet during the winter season. The dampness on a dirty carpet makes this bacteria for thriving. It is dangerous and can cause an illness referred to as campylobacteriosis, and the risk is even higher for small children and the elderly. You may have cramping, fever, bloody diarrhea and abdominal pain as signs of this disease.

Norovirus or the Norwalk Virus

The symptoms of this virus resemble those of stomach flu or food poisoning. This allergen can stay alive for up to four to six weeks in a dirty carpet. When people walk on the carpet, the allergen becomes airborne, and that is how it causes illness. People who like in areas with a lot of dust are more prone to norovirus.


A dirty carpet can be home to this allergen. It can result in deadly skin infections and other illnesses such as shock, and meningitis. The effects are severe for people with compromised immune systems. Sometimes, it can even lead to death.

Fungi & Mold

Various types of fungi and mold reside in a dirty carpet, and they can result in severe allergies and death in worse cases. Examples of these fundi and mold include Aspergillus, Geotrichum, and Rhizopus.

If you do not regularly have a professional clean your carpet, then it might harbor fungus, bacteria and various irritants at a breakneck pace. You should, therefore, clean your carpet but also take it for a deep professional cleaning sometimes. Otherwise, your dirty carpet will make you and your family sick.
