I have been getting bit all over my body and in my hair by tiny white mites that look like tiny grains of sand. I have been to the doctors at least 12 times about this, and no one knows what they are. I do not have lice or scabies. I hired an exterminator , he says we don't have fleas, ticks, or bedbugs. He could not find anything. I have bombed the house about 8 times, but I still see these white tiny things all over the house, on my clothes, and in my hair. About 2 weeks ago I finally called it quits and now I am living in hotels. However even though I have left the house these bugs are still in my hair biting me. I have tried everything! Please Help
