What are eyelash mites and how to get rid of eyelash bugs

It’s estimated that by age 60, 84% of the population will have an overgrowth of eyelash mites.2

Eyelash Mites

Why is there bugs on your eyelashes? – Eyelash mites are microscopic parasites, organisms which thrive off a host. In mammals, they eat skin cells, dirt and oils.1

Are eyelash mites real? Believe it or not, we all have some of these eyelash creatures living in our eyelashes. The eyelash mite, also known as Demodex, is a parasite that can be found living in or around the follicles of the eyelash. For most people, these eyelash mites will be unnoticeable. For others, too many eyelash mites will be the cause of a condition called demodicosis.1

Can you see eyelash mites? Eyelash parasites are too tiny to be seen by the naked eye. In the adult stage, the eyelash parasite is only 0.3 to 0.4 mm in length and requires a skin scraping or biopsy to be accurately diagnosed. When an eyelash mite infestation occurs, the follicles will become blocked, leading to an allergic reaction or inflammation.1

Does Everyone Have Eyelash Mites?

Even healthy individuals will have lash mites, however for some people these mites may multiply in number. When this happens, excess eyelash parasites may cause a variety of symptoms that require treatment. With Demodex mites, eyelashes are just one of the hair follicles that can be affected. These parasites can spread to other skin areas such as the forehead, cheeks, chin, and brows.1,2

The number of eyelash mites in humans increases as we age, with 84% of the population having an overabundance of the parasite at the age of 60. While eyelash mites are not present when we’re born, these mites will pass to newborns through physical contact with parents and other family members.1,2

Too Many Eye Mites: Demodicosis

How do you get eyelash mites? As mentioned previously, we all have eyelash mites. While they generally do not cause symptoms, these parasites can become problematic when an infestation occurs. As well, people with an immune deficiency or a hypersensitivity to the parasite can also develop acute symptoms that require treatment.1

Demodicosis is diagnosed by sampling the eyelashes and counting the number of eyelash mites on each.  A normal count of eyelash mites is below 5 mites per eye. Numbers over 5 mites may be are labeled as a case of demodicosis.3

There are a number of factors that can lead to having too many eyelash mites, which can cause mild to severe symptoms. One of the leading causes of demodicosis is the use of makeup, particularly mascara, that is old and filled with bacteria. Using this dirty makeup allows eyelash mites to spread.1,4

Inadequate daily cleansing of the eye area is another cause of high counts of eyelash mites. Going to bed at night without thoroughly washing off all makeup and buildup of oils may also be a cause of lash parasites.2

Having a dog may increase your risk of getting demodicosis, as animals are also vulnerable to eyelash parasites. A veterinarian can help determine if your pet should be treated for eyelash mites.1
