Not sure which type of beetle they are. They are small, brown and can fly. We had an infestation surrounded by our kitchen last year, which we be able to do away with after finding the nest in some out-of-date grain. But very soon they are appearing in my bedroom. I with the sole purpose usually see one in a fortnight, whereas within the kitchen we used to find at least 20 a daylight. And I can't locate a nest anywhere. I don't smoke and I don't keep food contained by my room. So where the heck are they coming from and how can I gain rid of them?
Answers:    Do you have any potted plants within your room? If you do that could be the source of your buggies. They live in the soil.
If you do contained by fact enjoy plants with infested soil later a mild solution of dish soap and water sprayed on the plant and over the soil should do the trick.
Good Luck
