Dust mites are home parasites belonging to the arthropod family. Their habitat is dust, and the source of food is dead cells of human skin. Dust mites are unpretentious and can survive in almost any conditions. The most favorable environment for their living is warm and humid, the temperature – about 21 degrees of heat, that is the one that is installed in residential premises, an abundance of food (epithelium). This explains their wide distribution.
These bugs can cause allergies, and their prolonged exposure to humans can lead to the development of sinusitis, asthma, and other health problems. Besides, they provoke a disease such as scabies, that occurs during regular contact with the products of their vital activity.
That is why it is important to know:
- if you have dust mites
- what do dust mites look like
- can you see dust mites with your own eyes
- and how to get rid of them.
What Do Dust Mites Look Like – Picture Under a Microscope
Dust mites are invisible to the naked human eye because their length reaches only 0.5 mm. To study the details of the structure of their body is possible only with a microscope.
One gram of house dust can contain from hundreds to thousands of parasites. This type of bug, as well as all spiders, has flattened body shape, consisting of interconnected individual segments. It moves with eight legs. There are suckers on each limb, thanks to which the harmful microorganism is firmly attached to the surfaces. With the help of two pairs of jaws, the parasite captures and grinds food, and also pierces the skin of the host, as some mistakenly believe.
The body of dust mites covered a kind of water-repellent layer. If we look at the parasite under the microscope, we can notice that it looks like an ordinary small spider. There are about 150 species of mites that live in house dust.
Where Do Dust Mites Live?
Most often, dust mites are concentrated in a dusty environment of difficult to access places, as well as in bedding. They can be found:

Allergic Reaction to Dust Mites
Dust mites – the source of the strongest allergic reactions. They affect the mucous membrane of the respiratory tract and cause:

- Respiratory allergies;
- Atopic dermatitis;
- Bronchial asthma.
On the occurrence of allergies provoked by mites, indicate such symptoms as frequent sneezing, itchy eyes, the appearance of wheezing in the chest, and choking cough.
This disease is diagnosed based on data collection, blood tests and microbiological tests.
Treat dust mite allergies by limiting patient contact with allergens, the use of medications, and desensitization. These are measures aimed at reducing the body’s perception of allergens. For these purposes, an allergen extract is administered to the person, gradually increasing the dosage and concentration. With the help of desensitization, the body does not react so strongly to the source of irritation.
