These bugs for 4 years I've tried it all from bleach alcohol hand sanitizer mint peroxide bug spray insect spray throwing everything away starting over and still same they are bad they hurt they itch in the head mostly. They fall feel wet but they dry like stickers there black white cream brown they feel like little balls rolling off your head they even feel heavy at times and leave there nasty feces I would say on your clothes Cuz it changes color and you see the bugs when u git them on your clothes they latch on like ticks

Why not have a doctor look at the "bugs".. Sounds a bit strange to me-4 years?

I'll take a wild guess. THRIPS. 6,000 species. Yes, they can bite. Yes they can get in your hair. https://bugguide.net/node/view/7754

I haven't heard about this kind of bugs... its really strange

Take some transparent cellophane tape and catch 3 or 4. Stick the tape to a white card for contrast. Take this specimen to a University or an Exterminator's office for identification. You cannot solve the problem until you identify it.
