Dust mite: a photo of how the symptoms on the skin and insects look under a microscope, what size these creatures are, bite and how to detect in the apartment and on the body?

Dust mites are synanthropic insects that live in humans.

Sinanthropus is a creature whose life is closely connected with people. Without coexistence with humans, these insects cannot survive. In most cases, saprophytes are harmless to humans. House dust mites are literally ubiquitous!

What is the size of these creatures?

The size of insects is microscopic, the largest individual reaches 0.1-0.2 mm. It is impossible to see them with the naked eye, only under a microscope.

Note! Pests can cause irreparable harm to human health. The concentration of insects up to 100-150 pcs. on 1 gr. dust is safe for health. A higher tick content will cause allergic reactions, conjunctivitis or asthma.

How they look - description and photo

Dust mites belong to the arachnid genus. You can consider them only under a microscope, which increases by 40-50 times.

Insects themselves

Ticks look rather unpleasant and disgust. Their body is oval and large, in relation to the legs. A proboscis is attached to it, which is similar in shape to tentacles. The legs of the insect are six. They have suction cups on which they are attached to different surfaces.

Insects live in high humidity. The arthropod life cycle is 60-85 days. The female can lay up to 300 eggs.

Symptoms in humans

Many people are mistaken about whether these unwanted housemates bite. In fact dust mites do not bite or suck blood like spring mites. They feed on the dead cells of the upper layer of the skin, as well as their deceased relatives. Pests do not spread any disease.

If you notice bites on your body, you may have bed bugs or other parasites.

The danger to humans is that ticks can cause allergic reactions. More precisely, not the insects themselves, but their feces, which contain digestive proteins. These enzymes destroy human skin cells and cause various dermatitis. Fecal balls along with dust spread throughout the room and together with the air enter the lungs of a person.

The pest during its existence produces excrement 200-250 times its own weight.

Regular inhalation of large amounts of tick waste can lead to development:

bronchial asthma;
allergic rhinitis;
frequent diseases of acute respiratory viral infections and acute respiratory infections.

Dust mites are especially dangerous for children. At the age of 5-6 years, they are prone to allergic reactions. Insects can contribute to the rapid development of the disease and complicate its course. therefore it is necessary to carry out wet cleaning of the apartment daily if there is a small child at home.

Ventilate the apartment regularly, monitor the humidity. It should not be higher than 50%.

How to detect - step by step instructions

Due to the microscopic size of insects, it is impossible to see them. In any room there is dust and dust mites are present in it. The number of pests per 1 gr. dust ranges from 100 to 10,000. thousand.

In the apartment

There are 3 ways to detect ticks and their excrement in the apartment:

using a microscope;
make analysis in specialized laboratories;
using chemical test control systems.

With a microscope

Through a microscope, dust mites can be clearly seen if dust is examined.. Such a device is rarely bought home. You need to be able to work with him correctly. To do this, you need:

Microscope.
Two glasses: subject and integumentary.
Between them place a dust sample.
Glue the glass together.
Closely examine for ticks.

Analysis in specialized laboratories

To determine the insects in the dust and their number, you can do its analysis in specialized laboratories. It is advisable to make such a test for those who have an allergy of unknown origin.

Chemical Test Control Systems

To independently detect ticks at home, you can use the dust mite test. You can buy it in online stores. Step by step insect detection:

Before starting the test, check for completeness.
Vacuum up the dust in a few minutes.
Pour the chemical solution into the dust container. Close the lid and shake gently to mix thoroughly. Leave for the time specified in the instructions for the test.
Be careful when handling chemical compounds. Wear gloves to prevent chemicals from getting on your skin.
Prepare a test cassette. Drop a few drops of the solution into the hole. Leave on for 10 minutes.
Rate the result.

Detailed instructions are attached to the test, with which you can correctly evaluate the result.

On the skin

Redness and peeling may appear on the skin.. This should be a signal that you may be allergic to dust mites. For an accurate determination, you need to contact an allergist. He will prescribe a blood test to determine specific antibodies. Their presence will confirm allergy to dust mites.

Dust mites insidious insects. People with strong immunity are not afraid of them. At risk: allergies, children and the elderly. Often do wet cleaning in the apartment, use washing vacuum cleaners and air purifiers.
