Having itchy eyes? There could be mites in your eyelashes. This might sound shocking, but it’s true.
Don’t freak out almost everyone has them, proven by previous researches at North Carolina State University. These mites are also found on the sides of the nose, cheek, chin, forehead and even eyebrows.
These little mites are known as Demodex mites and out of their 48000 species, only two live on the human skin i.e. Demodex Brevis and Demodex Folliculorum. The first one to be discovered was Demodex Folliculorum way back in 1842 by a scientist named Simon; whereas, Demodex Brevis was discovered in 1963 by a researcher named Akbulatova.
Now let’s have a closer look at the two so we may have a better idea about their daily routine. You can’t see them with a naked eye so you will need a microscope, even a compound microscope can do the work. Under the microscope, you will observe that the Demodex Folliculorum is 0.4millimeter long, the other one i.e. Demodex Brevis is relatively shorter with the length of 0.2millimeter. Both have elongated body which is semi transparent and divided into two segments. They have eight legs and are quite similar to worms. Their bodies are covered with scales which help them to cling with the hair follicles. Inside the mouth, there are tiny needle-like structures which help them eat dead skin cells and sebum that is produced inside the hair follicle.
The most visible difference between the lifestyle of these two species of mites is that the Domedex Brevis lives deep inside the sebaceous glands and doesn’t leave its place unless it’s ready for mating. On the other hand, the Demodex Folliculorum remains at the root of the eyelashes and mobilize more frequently.

Another difference between the two is that Demodex Folliculorum prefers to live in the form of clusters; whereas, Demodex Brevis prefer to live in isolation.
The mites reside inside the eyelash follicle with their heads inwards. The male usually comes out of the follicle for the sake of mating; on the other hand, the female doesn’t leave its place. This process usually takes place at night, as they become active in the dark. A female mite can lay up to 25 eggs at a time inside a single eyelash follicle. As the mites mature, they leave the follicle and find themselves new follicles to reside on. The mite needs 14 to 18 days to increase its population.
They also find new hosts either by direct contact or through dust containing their eggs.
