Bed dust mites – what do they look like and how to get rid of them?

Dust mites , or bed mites , are domestic parasites belonging to the arthropod family. Their habitat is dust, and their food source is dead human skin cells. Bed mites are unpretentious and can survive in almost any conditions. The most favorable environment for their living is warm and humid, the temperature is about 21 degrees Celsius, that is, the one that is installed in living quarters, and there is an abundance of food (epithelium). This explains their wide distribution.

Such parasites can cause allergies, and prolonged exposure to them can lead to the development of sinusitis and even asthma. In addition, the scabies mite provokes a disease such as scabies, which occurs with regular contact with its waste products.

That is why it is important to know what a tick that lives at home looks like and how to get rid of it.

You may be confusing dust mites with bed bugs or marks on your skin with bed bug bites.

Main types of house ticks

House ticks are a separate biological group of parasites that live in the residential environment. They not only spoil food, clothing and furniture, but also affect the health of humans and animals.

The following types of ticks can appear and reproduce in the living environment:

• Hairy house tick . This pest lives in flour, grain, plant and animal residues, and even in cheese and tobacco. Such mites actively develop at a temperature of 23-25 ​​degrees and a relative air humidity of 80-90%. They can cause dermatitis in humans;
• Scabies mite (itching) . It develops and parasitizes only on humans in high humidity and warmth. It is the causative agent of scabies;
• Rat mite . The parasite primarily attacks rats, but, in the absence of a natural host, can attack other mammals, as well as humans. Rat mites cause a difficult to treat disease - rat mite dermatitis. This parasite is common in rural areas and poses a danger to its inhabitants;
• Chicken mite . This type of parasite is widespread throughout the world. Mainly lives in nests and droppings of birds, cracks of wooden surfaces. Can parasitize on the surface of human skin, causing skin rashes and irritations;
• Bird mite . This tick parasitizes wild and domestic birds, that is, it lives in close proximity to humans and is capable of attacking them.

Household ticks are dangerous not only because of their bites, but also because of the impact of their own feces on humans and pets.

Folk recipes

Some people are afraid to use chemicals. In this case, you can remove the ticks using improvised means. To do this, take 25 ml of liquid soap and dilute it in a liter of clean water. Half a glass of ammonia is also added there. The resulting mixture is thoroughly mixed. All rooms are treated with it and used for washing clothes.

Parasites do not like some plants, so dry bunches should be distributed in areas where ticks live. Tansy, wild rosemary, and wormwood are suitable. Vinegar, boric acid or turpentine are used as floor cleaners. They are bred in a bucket of water. To prepare a concentrated solution, 1 teaspoon is enough.

What a dust mite looks like - photo under a microscope

Dust mites are invisible to the naked eye because they are only 0.5 mm long. It is possible to study the details of the structure of his body only with the help of a microscope.

One gram of house dust can contain from hundreds to thousands of parasites. It is known that their numbers increase significantly from August to October, especially after the start of the heating season.

A tick of this species, like all arachnids, has a flattened body, consisting of individual segments connected to each other. The linen mite moves with eight legs. Each limb has suction cups, thanks to which the harmful microorganism is firmly attached to 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 is covered with a kind of water-repellent layer. If you examine the parasite using a microscope, you can come to the conclusion that it looks like an ordinary small spider. About 150 species of mites are known to live in house dust.

Where do dust mites start and live?

Most often, dust mites are concentrated in dusty environments that are difficult to clean, as well as in bedding. They can be found:

• In a pillow filled with natural bird feathers;
• In the mattress, especially if it is old and has not been cleaned for a long time. It is claimed that such mattresses consist of 10% mites;

• In soft toys made from natural materials;
• In stale old clothes;
• In woolen blankets.

According to the Federal Budgetary Institution “Center for Hygienic Education of the Population” of Rospotrebnadzor, one gram of dust contains from 10 to 10,000 dust mites. In addition to them, about 350 thousand colonies of bacteria and about 100 thousand clusters of fungi live on bed linen.

The waste products of sofa mites, which cause allergic reactions, enter the air, slowly settle on the surface and gradually accumulate. Allergens get not only onto furniture and things, but also onto human skin and even into the respiratory tract.

Step-by-step instructions on how to detect them

In the apartment

Finding dust mites in an apartment is problematic. Due to their microscopic size it is impossible to see them, but these creatures live in varying quantities wherever people live. If a person does not have any allergic reactions, most likely the concentration of mites in his apartment is low. The owner may not even know about the existence of these parasites in his home. If any unusual reactions of the body to inhaled dust appear, it can be assumed that uninvited guests live in the apartment.

If you suspect the existence of parasites in your apartment, you can purchase special test strips at the pharmacy that can easily detect dust mite allergens and determine their number. In addition, you can invite a special team involved in the fight against parasites. Specialists will take dust samples and, if parasites are found, will carry out a complete disinfection of the home.

How do bed ticks bite? Do they bite?

Many people are concerned about whether mattress mites bite and, accordingly, what the bite looks like. This type of parasite does not bite and does not spread infection. This is due to the fact that the pests are too small and cannot bite through human skin.

The cushion mite causes harm in a different way, through its metabolic products. These include:

1. Cuticle remaining after molting;
2. Secretions produced by parasites;
3. Feces that contain proteins that cause allergic reactions.

Those who are predisposed to allergies should be especially careful, because the parasite causes extremely unpleasant symptoms that can develop into a serious illness. That is why, if alarming signs are detected, it is worth contacting an allergist or immunologist to check for suspected tick allergies.

The rash that appears on the skin in response to the activity of the mite is confused by some with bed bug bites. In fact, bed bugs, unlike ticks, leave very specific bites: they are numerous and grouped, looking like large swellings with a pronounced red seal in the middle.

• Refuse drapery on the windows and choose blinds;
• Keep air humidity less than 40%;
• Ventilate the room regularly;
• Bedding should ideally be replaced with padding polyester or other artificial materials;
• Wash and comb your pets regularly.

Allergic reaction to bed dust mites

Dust mites are a source of severe allergic reactions. They affect the mucous membrane of the respiratory tract and cause:

1. Conjunctivitis, rhinitis, allergic dermatitis;
2. Respiratory allergosis;
3. Rhinoconjunctivitis;
4. Quincke's edema;
5. Bronchial asthma.

In medicine, such a reaction to household parasites is called tick-borne sensitization .

The occurrence of an allergy caused by bed mites is indicated by such signs as frequent sneezing, wheezing in the chest, suffocating cough, lacrimation, and red eyes.

This disease is diagnosed based on data collection, blood tests and microbiological studies.

Allergy to dust mites is treated by limiting the patient's contact with allergens, using medications, and desensitization. These are measures aimed at reducing the body's perception of allergens. For these purposes, an allergen extract is administered to a person, gradually increasing the dosage and concentration. With the help of desensitization, the allergic person’s body does not react so strongly to the source of irritation.
