I live in a cold climate (NH) but it is warm indoors all winter - especially in office/herp room (warm enough for them to survive, even if their cycling might be slowed down).
I kept Luna and all the feeders upstairs and one day I was downstairs in the total opposite end of the house and lifted something to find an adult lobster with about 20 nymphs. UGH! I know many people do the vaseline, bug blocker and other means to keep them from climbing, which I did for a while, but it is quite messy and it was just not worth the hassle. The discoids and Orangeheads are fine. Though I did recently switch caging on a pet hisser and forgot that they CAN climb and she got out. Would not be surprised if she is living just a matter of feet away from me!
So that is my personal experience with climbers, though I know many keepers/breeders use them.
