sorry to hear of the BBs it is a problem even here in Australia, as mentioned you have to wash everything in hot hot water and pop into a hot dryer, vaccuum the matress and burn the bag of waste then spray the mattress with fly spray or a bug spray and leave in the sun for a few days too. you may have to repeat the treatment a few times. to get the eggs as they hatch. not sure about the life cycle of BBs but most eggs hatch within 3 weeks so you would need to treat it for at least that long to make sure you get them. other than this throw it all out and fumigate the room leave it sealed for a couple of weeks and then redecorate.
