Hi, My girlfriend and I have been getting bit for about 10 days now. Some bites are approx. 1/4 inch and some are tiny pin prick size. I've taken photos of everything I've found throughout the house. I had an exterminator come and do a thorough inspection for bed bugs but he found no evidence. I have bug interceptors in various places and have caught nothing. I've only had a few, what I believe to be, mites, crawling on me, since pigeons have nested outside of our house. Here are all my pictures. I'm worried about bed bugs more than mites and generally just paranoid all around.
Ok, those are definitely mites. The magnified images may help an acarologist (mite expert) identify them, but I cannot. You might try Dr. Barry O'Connor at the University of Michigan. Tell him I sent you. He is usually very cordial and helpful to the public. Hope this problem resolves itself for you quickly, with little or no expense.
