Take a look at the rhizomes. If they're firm and plump, they might be Ok. I would remove almost all the pitchers. If any of the bases of the pitchers are green and firm (not dry or wrinkly), you can leave them on. Take all the plants out of the fridge and give them a good airing out. Maybe clean the drawers with 1/10 strength Bleach or more dilute if that's too stinky. Daily open the drawers and give them some air. Leave the sliding parts open on the fruit drawers to keep the humidity down. Maybe No-Damp.
