Entomology (Study of Bugs)/black beetle in bedroom


Can you please help me to identify this bug I've been finding all over our bedroom? They are tiny, black beetles that are attracted to light, or anything light-colored (like the white comforter). I'm not sure if they fly or not, but they do seem to congregate in the ceiling lights (has a dome that they fall into and die). They don't bite, are really slow moving and don't seem to do much. 6 legs, 2 antenna feelers, and black/dark brown hard-shelled body.
Thank you for your time!

Dear Kati - Without seeing an image, I can only guess at what you may have. I suspect that they may be carpet beetles (often resemble miniature lady beetles), but there are several other possibilities as well. Take a look at the images of carpet beetles at,, and to see if any of them resemble your unwanted 'guests', and if none of them do, please try to obtain a clear, close-up photo of at least one of yours and attach it to a follow-up question.
Waiting to hear back,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
