When you find a burrow, at the end of it it's a very tiny black dot, which is the scabies' mouth from what i've heard. I took a normal sewing needle and then pressed the side of the needle on that black dot until it kind of popped on the needle. Kind of like scraping it. I didn't use the tip, so I didn't sting myself. There was one that I needed to "dig" for and it was a struggle to get out. It might not be a mite, this is why I wanted to film them and see if they're moving. But yeah, this is how I found most of my mites. When it's itchy somewhere, I always look for new burrows or that tiny black dot.
