My husband & I thought we had gotten head lice from somewhere so we treated ourselves w/ Rid it didnt work so we tried Nix we still had the problem so we tried smart sense but still finding small black specks some tan colored  what I call egg bags also some small red ones. We went to the doctor he said it sounds like you have treated them gave us an itch pill & sent us on our way . Someone told us to try white vinegar this did help it kills them & we are able to comb them out but they just keep coming we fell a tickle & sure enough if we comb w/ a nit comb there they are in the sink some are so small u need a magnifying glass to see them I also have tore my entire house apart & cleaned everything in it from top to bottom we are living in the kitchen on to plastic chairs other than the bathroom &  bedroom I wash bedding every day what do we have & what do we do help please my father could die at any time now I need to get this taken care of thank you You should also know that my husband developed a rash & he get the black specks in the rash also we find them in the pubic area more my husband than me I have found a few but not as much as him in the morning it appears that its about over but by noon their seem to be more black speck that we comb out so we just keep using more vinegar . we also tried very hot towles on our head olive oil for 8 hrs. w/ plastic on our heads & mayo  short of going crazy  Ill stop now you get the idea
