My guess, they are Clothes moths.

if this is the case they are probably feeding off clothing or your carpets (natural fibres only) if you cant find them in clothing, check the corners and edges of the room, behind and under furniture etc even hanging off the bottom of furniture.
You can still but moth ball but they make everything stink! just get any insecticide liquid, maybe a cheap flea or ant killer from the pet shop or similar and spray all infested areas.
