The term "itch mite" refers to a small arachnid, scientifically known as Sarcoptes scabiei, that burrows into the skin of humans and animals, causing an intense itching sensation. However, there are several other terms used to describe this irritating creature. These include "scabies mite," "sarcoptic mite," "acarid," and "mite parasite." Some also use the term "itch parasite" to refer to the mite. Regardless of the name used, the common denominator is the discomfort caused by these tiny creatures, which can be treated with topical medications prescribed by a medical professional.
