While demodex mites can only live a few hours off of the human skin in a dry environment, in a wet or damp environment they can live for days. (Source). A mascara tube is not a great environment for demodex to live, as they have nothing to feed off of and nowhere to lay their eggs safely.
A high risk of transmission of Demodex spp. is associated with using the same mascara, in which the mite was found to survive up to 56 h.
Patients with Demodex are typically prescribed an eyelid cleanser that contains tea tree oil twice daily in order to eradicate the Demodex mites. They are instructed to cleanse the lids and lashes, as well as smear the lid cleanser onto the eyelash roots of both the upper and lower eyelid margin.
At high concentrations, tea tree oil is a potent killer of Demodex mites. The problem is that solutions of 100% tea oil, or other high concentrations, are very irritating to the eye. So one approach is to thoroughly wipe the eyelashes and eyebrows with a diluted solution of tea tree oil, from 5% to 50%.
"Demodex mites live on our skin and are especially prominent in areas where we have a lot of oil like the face or the middle of the chest." Even worse, said mites thrive in unsanitary environments, like Xu's dirty pillowcase.
Dear Reader: Eyelash mites, also known as Demodex mites, are a type of eight-legged parasite. They live in or near the hair follicles on the face and eyes and are found primarily near the eyelashes and the eyebrows.

"The total life cycle of mites is several weeks,” says Lam. “But I usually have patients on tea tree wipes for at least 30 to 60 days, depending on the severity of the condition.” In-office procedures, such as eyelid microexfoliation, may also be recommended to offer relief to those with blepharitis-related issues.
Demodex mites occupying deeper regions of hair follicles cause dislocation of the base of the hair. These changes may lead to excessive loss of eyelashes and eyebrows [3, 6, 7]. Infested follicles usually contain 2–6 parasites, but they may sometimes be even more numerous [8].
Conclusions: Makeup cosmetics used by different individuals at short intervals (from several hours to several days) can be a source of transmission of Demodex sp. mites.
Temperatures below 0 degrees C and above 37 degrees C are harmful to the mites. The lethal temperature is 54 degrees C, and the effective temperature that kills Demodex mites is 58 degrees C.
They're known as Demodex or eyelash mites, and just about every adult human alive has a population living on them. The mostly transparent critters are too small to see with the naked eye.
Microscopic Demodex mites are attracted to the oils that build up on our eyelashes. If the lashes remain dirty, the mites can overpopulate, causing inflammation and itchiness along the eyelids, says Dr. Husain. If infection sets in, a woman's healthy, natural eyelashes may fall out and never regrow.
Possible Impact of Demodex Diagnosis
Formication, a sensation resembling that of insects crawling on or under the skin, is a specific form of the general set of abnormal skin sensations known as paresthesias (prickling, tingling sensation of “pins and needles”) and tactile hallucinations.
But don't freak out – almost every human eyelash contains microscopic parasitic mites. Despite their generally harmless nature and mutualism with us, these bacteria can sometimes cause itchy, crusty, red, and bumpy eyelids.
Treatment for a mite infestation usually involves a cream, gel, lotion or wash containing an acaricide. An acaricide is a pesticide that kills ticks and mites. Your healthcare provider may recommend: Benzyl benzoate.
Gliding through grease, and protected by our pores, tiny Demodex folliculorum mites lead a secretive life within our skin, only emerging at night to mate on our foreheads, noses and nipples.
Among them, only Demodex mites are permanent ectoparasites of human and other mammalian pilosebaceous unit. A total of 140 species or subspecies have been identified worldwide in 11 orders of mammals including humans (1).
Prevalence of Demodex infestation increases with age, with a reported 84% in people >60 and 100% of patients >70 years of age. Direct contact is needed to transfer mites from one person to another, most probably through common household items such as linen, towels and toiletries.
By age 70, every individual has at least 1000-2000 mites. Men are almost twice as likely to experience demodicosis, perhaps because women regularly cleanse their eyelids with eye makeup remover.
The actual name for these bugs are “Eyelash Mites” or Demodex Folliculitis. The mites are a parasite that lives in the hair follicles of the face. They feed off of the oil, build up and bacteria in the follicle. They can overpopulate if you don't properly clean your makeup brushes and change your mascara wands.
The parasitic mite, Demodex folliculorum, lives in the hair follicles in humans and certain other mammals, especially around the nose and eyelashes.
Both male and female Demodex mites have a genital opening and fertilization is internal. Mating takes place in the follicle opening and eggs are laid inside the hair follicles or sebaceous glands. The six-legged larvae hatch after 3-4 days, and the larvae develop into adults in about 7 days.
Washing your face will not get rid of them as they live under your pores. All humans have face mites but they only become an issue when they increase in number resulting in a condition called demodicosis.
