Demodex the face mite on my forehead!

Hi Microcosmos!

There are many things I’ve wanted to image with Foldscope. One of which is Demodex, which is a face mite species that live on the faces of every one of us humans.

Tonight, I’ve finally found one on my forehead! Yay!

Ok, ok, mites on our faces. Some might say… EW! But hear me out 🙂

They are part of our personal ecosystem; our human microbiome. And it’s nice to know that we have microscopic pets on our faces everywhere we go. Aren’t they kind of cute? No?

Cute or not cute (I think they are cute), you can catch your own mite and see for yourself! And it’s super easy!

All you need to do is stick a piece of clear tape across your forehead for a few hours. The longer you leave the piece of tape the more chance of you catching the Demodex. I left my piece of tape on for 6 hours.

Then you carefully remove the strip of tape, and stick it on top of a blank glass slide.

Then insert the slide into your Foldscope and scan for your mites!

It took me 40-50 min to scan the entire strip of tape to find one mite which you are seeing below. So it may take some patience.

Have fun!

    Absolutely brilliant @honomi. Sometimes combination of patience, deligence and creativity is the answer to most science problems.

    Fantastic!! Will put on my tape on the forehead right now. It’s a great conversation starter!!

    Oh my goodness. I have been searching for these forever and thinking that I am Demodex free.. 6 hours sounds like a good time. That is what I shall do. Hope to find them on my face too.

    @Manu @Laks
    Looking forward to your mites!

    I had the general idea of what a face mite might look like, but I didn’t know how small/large it would look with the Foldscope 140x lens. Every speck I would encounter on the tape, I stopped to examine it for a long time to make sure I wasn’t missing it. (And yes, there were dirt, makeup, fiber, hair, and old skin…yuck)

    Once I spotted the mite, it was hard to miss. The shape of the mite really stands out from the rest of the yuck factors.

    I’ll have to figure out how to capture them live because the mite on this post did not move at all :/
