These are Hide or Larder Beetle larvae (genus Dermestes). Here is an illustration of a Dermestes maculatus larva. There may be a dead mouse or other animal somewhere near your bedroom and the larvae feed on the carcass.
Thank you for your speedy response and very helpful information!
The main place we Have these are in our bedroom, most are dead though, our room is very small and im pretty sure there is no access to our floorboards upstairs for a rodent. Do they only feed on carcass's? and are they harmful?
