Dust mites

The house dust mite is also called Dermatophagoides oteronyssinus, this is the Latin name. The dust mite, as the name suggests, occurs in dust. Dust mites are mainly found in homes. The dust mite lives on organic material. Organic material can be found in many places in the home, such as human and pet flakes lying everywhere. Dust mites are found wherever dust and dander are found. So on the floor, in the couch, in the mattress, etc. They also do well on semen, so the sheets also contain dust mites.

The life of a mite

The dust mites cannot be seen with the naked eye. It is a small creature that looks like a spider. It is 0.3 mm in size, so it is only visible under a microscope. House dust mites find a temperature of 245 degrees very pleasant, as does a humid environment. An air humidity of 50 to 75 percent is ideal for dust mites. The house dust mite lays three to five eggs per day. After a few months the dust mites die. Unfortunately, humans cannot remove all dust mites, especially from mattresses. Ultimately, a mattress will contain many dead dust mites. Dust mites can be removed from carpeting with a cleaning device. Cushions can easily be washed in the washing machine.

Remove dust mites

It is unavoidable that dust mites are present in a home. However, it can be limited as much as possible. First of all, by vacuuming and cleaning thoroughly every day, so that no dander is left to grab. Furthermore, ventilate the home well, so that the humidity is reduced. Don’t give mold a chance, because that’s what dust mites feed on. Pillows can be washed and many mattresses nowadays have a washable cover. Some mattresses are even anti-allergic.


An allergy to house dust mites can manifest itself in asthma or eczema. However, people are not allergic to the dust mites themselves, but to the droppings and flakes they leave behind. People with asthma and eczema are therefore advised to thoroughly clean and ventilate their home every day. It is not clear why one person develops an allergy to house dust mites and another does not. Hereditary may play a role in this. Early exposure to tobacco smoke and chemicals probably also plays a role, i.e. when the young child comes into contact with this at an early age. Pets also bring flakes with them, so people with asthma and eczema often do not have pets. Certain pets such as aquatic animals can often be kept without problems.

Removal of substances

It is best for someone with an allergy to take a critical look around them. Carpeting is not allowed, as it is full of dust mites. Mattresses can be fitted with a special anti-allergic cover. Pillows regular shafts. Stuffed animals are also often full of dust mites. Remove rugs and loose clothing from the floor. No fabric wall coverings. No curtains or fabric blinds.
