All about dust mites: how to protect your home from parasites?

Dust mites are microscopic animals belonging to the class of arachnids.

Oddly enough, ticks are close relatives of spiders and scorpions. In total, about 150 species of ticks are secreted. Dust mites live in close proximity to people.

As a rule, dust mites settle in feather pillows, behind the baseboard, in vacuum cleaner bags, that is, in all those places in which there is dust.

Features of the appearance of dust mites

Dust mite (Dermatophagoides).

The eggs of former ticks are microscopic. The color of the eggs is white. The dust mite larva is white, translucent. Larvae have 6 legs from birth.

Adult individuals do not exceed 0.5 millimeters in length. Outwardly, a dust mite resembles a microscopic spider. In adults, 8 limbs, each of which is equipped with special suction cups, with which the parasite is attached to the surface. It is because of these suction cups that the mite cannot be thrown off simply by shaking the laundry, and parasites cannot be removed with a vacuum cleaner. The body of dust mites is coated with a water repellent. The oral apparatus may be different, depending on the type of food.

Reproduction of dust mites

The entire development cycle of a dust mite is no more than 3 months. Already in the third week of life, individuals begin to breed. Dust mites mate in dark shelters. If the temperature is 18-25 degrees, the females begin to lay eggs. Egg laying occurs daily - one egg a day. Only one female brings about 60 eggs.

Young larvae emerge from the eggs and begin to actively search for food necessary for a series of molts to occur. Dust mites do not have a pupal stage.
Since dust mites have no natural enemies, they multiply incredibly fast. For example, in just six months, a colony of a million individuals will dwell in the mattress.

Oddly enough, but neither the larvae of these parasites, nor adults do harm directly to people. Danger is caused only by substances that are contained in the excrement of dust mites. These substances contain digestive enzymes that break down the epidermis in humans; in addition, they provoke a severe allergic reaction.

The effect of these enzymes is not noticeable for the body, if the number of dust mites does not exceed 100 individuals per 1 gram, but if it increases to 500 individuals, then an allergy develops.

These mites provoke all types of allergies: contact, respiratory and food. If dust mites live in the apartment, the owners can develop a large number of diseases: bronchial asthma, allergic rhinitis, conjunctivitis and a variety of dermatitis.

Signs of dust mites

The appearance of dust mites can be reported by itching on the skin.

Often a skin rash occurs, people complain of bites, but in reality they are not bites, but swelling that causes itching. These edema are the result of allergic reactions.

Ticks settle in beds, and since they defecate about 20 times a day, excrement balls remain everywhere. These excrement in large quantities is collected on wet skin, it is they that cause dermatitis in people prone to allergies. And in people who are not prone to allergies, sleeping in the same bed, there are no manifestations. The patient has the following symptoms: skin rash, itching, red eyes, depression of the body.
