Sorry to hear, I hope you can find both of them. Have you tried heating up a f/t feeder in that room to try to entice them out? For that tub or others if they're free standing you can use binder clips to help keep down the lids: they won't do much with bigger and stronger snakes but I've used them for my smaller ones. Currently I have 6 clips per tub for each of my little Cali Kings.
