House dust mites live on animal and human skin dander or hair. They prefer to find them in the dust and in beds, where they live in thousands.
The immune systems of people allergic to house dust and sensitive people react to the animal's feces by releasing large amounts of histamine.

But there are measures that make life difficult for them and reduce their number and thus the allergy triggers. From encasing to ventilation – how to decimate mites in the bedroom.
