I understood it to be a dead cock roach, the stomach acid is strong enoug to drive your pin worms out so thy can be seen. Otherwise I can't understand the people's languages in the video.
I assume all humans on the planet have these worms in their skin, all over their body. The old scotch tape method pulls the worms out as well. Take scotch tape and rip it off the skin and then look under a microscope to see pieces of the same worm.
When we sleep these worms come out and get in our bed sheets and lay their eggs everywhere. For this reason, herbs can't kill them all, NEVER EVER can you kill them all, they can hide from our blood and their eggs are EVERYWHERE.
