The mattresses are ideally perfect place for mites, but many do not know how these parasites look under a microscope.
The laboratory at the University of Ohio made a video on which you can clearly see the microscopically increased mites.
On the footage you can seen that the mites are surrounded in their own yellowish feces, and experts claim that they can expel feces up to 20 times a day.
Dust mites are very small creatures, with length of around a quarter of a millimeter and can cause a lot of allergies.
They feed on bits of human skin and are attracted by moisture, mattresses, cushions and soft furnishings.
Unfortunately, over 10 million mites can be found in a single mattress. After two years of using the pillow it becomes 10% heavier die to the mites and their feces.
Generally, dust mites are not dangerous, but can cause allergic reactions, asthma, fever and eczema.
