On a note!

A dust mite is a synanthropic creature, lives in a person’s dwelling, feeds on dead organics.

Habitat

If you carefully examine your own housing, dust can be detected almost everywhere. It is in these places that the household tick lives. The most common:

On a note!

There is no separate substance “dust”. The gray coating, which can be found in any room on window sills, furniture, carpets, is nothing but the waste products of microorganisms, particles of human skin, small living microorganisms.

Do dust mites bite

On the Internet pages you can often find photos of dust mite bites on the body. It looks like a numerous rash over the entire surface of the body or its individual sections. Farin dust mite, pteronissinus mite are the main provocateurs of household, contact allergies, but such a reaction of the human immune system in this way does not react to parasite bites. It is not possible to bite a dangerous pest anatomically.

On a note!

Household dust mites do not pierce human skin, so we can confidently say that these creatures do not bite. They feed exclusively on dead organics - particles of human skin, animals. Excrement, getting on the skin, contributes to the exfoliation of the stratum corneum, which provides an abundance of food.

Feces contain digestive enzymes - proteins Der f1, Der p1, antigen P1. These components provoke the development of a local allergic reaction to the skin and general. Excrement is so small that when you inhale it gets on the nasal mucosa. Penetrate into the respiratory tract.This is followed by an instantaneous reaction of the immune system, which is manifested by rhinitis, sneezing, coughing and other symptoms.

Signs of the presence of the parasite

Dust mites are present in every home, but not all people have a persistent reaction to their presence. It is all about the strength of immunity, which restrains or allows the development of a response.
