A study by Sean Tighe, Ying-Ying Gao, and Scheffer C . G . Tseng have demonstrated that the efficiency of 4-terpineol against demodex mites was more potent than the whole oil at equivalent concentrations, and its killing effect was even observable at concentrations as low as 1 %.

Other Prostigmata live as parasites on vertebrates ( e . g . " Demodex " mites of the Demodicidae ) or invertebrates ( e . g . " Polydiscia deuterosminthurus " of the Tanaupodidae or the honeybee tracheal mite, " Acarapis woodi ", of the Tarsonemidae ).

Delusional parasitosis is a mental disorder characterized by a fixed, false belief that a skin infestation exists, which is in contrast to cases of actual parasitosis, such as scabies and infestation with " Demodex ", in which a skin infestation is present and identifiable by a physician through physical examination or laboratory tests.

"Demodex " is a genus of mite in the stress, or malnutrition, the mites can reproduce rapidly, causing symptoms in sensitive dogs that range from mild irritation and hair loss on a small patch of skin to severe and widespread inflammation, secondary infection, and in rare cases can be a life-threatening condition.

In the vast majority of cases, the mites go unobserved, without any adverse symptoms, but in certain cases ( usually related to a suppressed immune system, caused by stress or illness ), mite populations can dramatically increase, resulting in a condition known as demodicosis or " Demodex " mite bite, characterised by itching, inflammation, and other skin disorders.

The closely related term, mange, is commonly used with domestic animals ( pets ) and also livestock and wild mammals, whenever hair-loss is involved . " Sarcoptes " and " Demodex " species are involved in mange, but both of these genera are also involved in human skin diseases ( by convention only, not called mange ) . " Sarcoptes " in humans is especially severe symptomatically, and causes the condition scabies noted above.
