I had little bugs crawling on me, in my hair and in my clothes. I kept finding black specks that didn't move. I would notice glitter on my face in the sun light. I didn't realize this was scabies. I washed, sprayed and bombed; nothing seemed to work. Unfortunately, I gave scabies to my friend. She told me the only way to get rid of these bugs was to get ivermectin.
My tip is if you are having little black specks and feeling like something is crawling all over your body, see your doctor and have them to prescribe ivermectin. :)
Many types of bugs are small and black, if they are biting bugs they can be annoying and a health hazard. This is a page about getting rid of tiny biting black bugs.
