"Ignorance more frequently begets confidence than does knowledge"
Demodex brevis lives alone in the body's sebaceous glands and feeds on the tissue as well as the oil produced by the gland. It also lives in the meibomian gland and the gland of Zeis.

Researchers generally agree that the lifespan of male mites is no more than 15 days (with one claiming 2-4 weeks). But estimates of female lifespans vary depending on whose research paper you read - from 15 to 24 to 60 days. If a mite is dislodged from the host, some researchers claim it will take from 24 to 38 hours to die. Others say that if the environment is dry, it will die in a few hours. But in a moist environment, like a just-used towel, it can survive for up to 58 hours.
- The Medscape Reference Library has an interesting article on human demodicosis written by Manolette R. Roque, MD, MBA.
- The Journal of Clinical and Aesthetic Dermatology also has a good study on demodex dermatitis by Joseph B. Bikowski, MD, FAAD and James Q. Del Rosso, DO, FAOCD.
For four months prior to the onset of my mother's illness, I put myself under enormous stress studying for an advanced video editing qualification. I felt I just had to pass that exam since a lot of money had been paid for the course. In the event, I did.
Does demodicosis fit the symptoms?
1. Tickles and some itching in the following places:
- Head: (Almost incessantly) around eyes and orbital ridges, eyebrows, cheeks, nose, nostril entrances, chin, forehead, temples, scalp, ears, ear canals, neck.
- Trunk: (Frequently) shoulders, chest, armpits, arms, back of hands and fingers, back, hips, abdomen, groin, scrotum, perineum, buttocks, anus.
- Legs: (Frequently) thighs, behind knees, shins, calves, feet, toes.
- Wandering males and virgin females (both types of mites).
- The insects 'struggles to exit the plug can cause the entire thing to be pushed out onto the surface of my skin, thus registering its sudden presence as a foreign body - a tickle, something to be brushed off. I believe this can also cause the popping sensation referred to below. Here's a freshly-ejected plug:
A plug that's just been ejected on my forehead. The larva can be seen breaking through the wall at the top.
2. Popping and hair-flick sensations like a soap bubble popping on my skin or a single hair being flicked:
- Scalp and eyebrows: (Frequently) these seem to be the main areas I get pops and hair-flicks.
- Trunk: (Infrequently) mostly abdomen, shoulders, arms, and back of hands and fingers.
- Pops: the plug being suddenly dislodged out of the skin onto the surface by the insects 'struggles.
- Pops: Demodex brevis breaking through the external wall of an embedded plug.
- Hair-flick: Demodex follicularum entering or exiting a follicle, causing the hair to move.
3. Sharp pain (Or "sting9rdquo; sensation) exactly like a hair being tugged hard (not as common as tickles or pops) in these areas:
- Legs: (Frequently) thighs.
- Trunk: (Infrequently) chest, armpits, abdomen, groin, scrotum, anus, back, hips, buttocks.
Pictures 1 and 2.
Picture 1 is the inflamed follicle about an hour or so after the initial "hair-tug9rdquo; pain. Picture 2 shows sebum outflow after the pale green top was punctured (black spots are soot from a sewing needle sterilised with a lighter). Picture 3 shows the results of deep-squeezing the site - an insect (or partial insect) is visible at the bottom in the serum. Picture 4 is after clean-up - notice the hair is now gone.

Natural and Organic Treatment s for Demodex in humans with:
Neem Oil, Lemon Grass Oil and other Natural Demodex Mites Killers
Demodicidosis is an opportunistic ectoparasitosis skin complaint, common to humans and many mammals, caused by the proliferation of Demodex in the pilosebaceous unit. The genus Demodex belongs to the arthropod Class Arachnida order and family Demodicides. Over 65 species have been recorded since the first description in тисячу вісімсот сімдесят один by Henle. Each species is unique vis-à-vis its host.

Treatment is based on topical anti-mite or acaricides, whose effectiveness is inconsistent. Crotamiton cream to 10 p. 100 (Eurax ®) is the most commonly therapeutic cream used. This araricide minor is the most active and well supported. It is applied to the wound healing at a rate of once per day in children and twice daily in adults. Lindane at 1 p. 100 form of preparation to be applied at night on the lesions is more rarely used. It can cause skin irritation. It is cons-indicated in children under 2 years and pregnant women and nursing. Lindane at 1 p. 100 in fluid cream.
People may also try natural oils such as neem, lemon grass oils, etc. These form a nice barrier that may help reduce minor infestations. Permethrin cream 5 p. 100 is a brief treatment with a single application every 8 to 12 hours, is more effective and better tolerated in the face as permethrin cream in a capillary p. 100 (Nix ®), which must be flushed after 10 minutes.
Chemicals and Antibiotics suppress immune system helping Demodex to multiply insted of killing the mite. Ask your doctor about possible side effects and how it can affect your daily demodex treatment.
Topical metronidazole, inactive in-vitro on Demodex, has some efficacy in vivo and is worth a try in the form of compounding at 1 or 2 p. 100 twice a day. Only the concentration to 0.75 percent. 100, indicated in rosacea, is currently available (such as Rozagel ®, Rozex ® cream or gel, Rosiced ® gel). Benzyl benzoate to 10 percent. 100 lotion (Ascabiol ®), active but very irritating especially in the face, was abandoned. The mercurial ointments and sulfur to 10 percent. 100 are very irritating and are no longer used.
