I have not sustained any bites, but I have been finding these all around my room. First I found the little bitty seed looking things. They are tiny, and come apart when pressed between my nails. Then I started finding other bugs as well. I do for sure have carpet beetles. (I recently had a friend stay over who admitted to me she has a bb infestation, hence the paranoia)
Edited to add the little seed like things
