Never had to deal with bed bugs, but I've had to deal with fleas. You can get this stuff called Borax...spread it all over the carpets and let it sit for an hour or so. It suffocates anything living in the carpet. Vaccuum it up afterwards. Again..not sure if that would work for bed bugs, but it works for fleas!

EDIT: By the way...I can't make it to your slumber party this weekend!
