It seems to be a sort or worm in a tube made of dust. And it can poke it's head at both end of the tube.

I see one every few month in my bedroom, never saw them elsewhere. I've got no idea what they eat or how they get in. It seems it smells pretty bad as well as I can smell a foul odor about 50 cm from it, despite the fact that it's about 1 cm long only.

Anyone knows what it is?
