Okay, what the heck are these crazy little worm-things that I keep finding on my carpet?  Where are they coming from?  How are they getting inside?  And, most important of all, how can I stop them?!

*has the heebie-jeebies*

P.S. A quick (very quick, see heebie-jeebies above) Google suggests they are neither centipedes nor millipedes ... though I guess they might be.  They've got legs, anyway.  What the heck are they?

P.P.S. They are not silverfish, nor roly-polies, nor house centipedes.  They are a little over an inch long, very narrow, with many short legs on the bottom, like a caterpillar has.  They are a dark red-brown in color.  I think they <i>might</i> be millipedes after all, in which case they're not dangerous, but they still completely gross me out!

P.P.P.S. captainardi had the link that identified them!  Millipedes it is:  Fourth photo down, here.  Ugh!  Now, how do I keep them out of my home?
