The dust mite is a microscopic representative of the animal world inaccessible to the human eye. Favorable breeding grounds are dark and gloomy corners, mostly among the dust, and the main habitat is the dwelling of people.
The first dust mites were found in apartments several hundred years ago. It is assumed that they were brought with feathers and down of poultry. Dust mites are the causative agents of a rather dangerous disease - bronchial asthma.
From the article, you will learn what symptoms are caused by dust mite bites, how they look on the human body, and you can look at a photo of an insect under a microscope.
Brief description of insects
Science has more than 150 species of dust mites. The most common are pyroglyph and barn species, which are referred to as house ticks.
The diet of these individuals is dead cells of the epidermis, falling off the human skin, particles of dandruff, as well as the pile of woolen carpets, blankets, and blankets. They prefer to live their life in the dusty corners of the dwelling, in the accumulation of old clothes, mattresses, upholstered furniture, on bookshelves ..
They feel great at 55% or more humidity in the room and an air temperature of 22 - 26 ° C. Two months is enough for this parasite to lay offspring of several tens of eggs. But the life cycle of an individual does not last long - about three months.
The size of one individual is from 0.1 mm, but some species can reach 0.5 mm. Up to one hundred dust mites can live in one gram of dust.
What do they look like?
The dust mite cannot be detected and viewed with the normal human eye. But under a microscope or under a magnifying glass, an adult looks intimidating. Its appearance resembles a yellow - brown chubby spider with eight sharp legs, each of which has a suction cup to hold the body on the surface. The pincers cling to objects with their paws so tightly that they cannot be thrown off the clothes or bed even by strong shaking. A vacuum cleaner is just as powerless in the fight against these animals (how to get rid of a dust mite at home?).
Do they bite? Dust mites are so small that a person cannot feel their presence on the body and feel bites. The only danger from these creatures is that with a large accumulation, they are quite capable of causing allergies in a person.
If an allergy to bites is found, do not comb the damaged areas, in order to avoid spreading to other areas of the skin.
The affected area should be immediately treated with soap or soda solution, an antiseptic is also suitable.
In order to reduce itching and inflammation, use:
- essential oil of conifers, wormwood, lavender, mint, cypress;
- freshly brewed black or green tea bags;
- you can drink several tablets of activated charcoal.
ATTENTION! The proposed agents have a softening effect on the skin, reduce itching, but do not cure allergy symptoms.
For treatment, you need to visit a doctor and take a course of prescribed medications. Among them, the most effective drugs can be distinguished:
