Advertisement Due to a need for more content to feature on my YT channel, my invert collection has been growing exponentially. As such, I've been heavily considering the benefits of a roach colony. Here in Australia, the most common feeder roach is Parcoblatta pennsylvanica. Anyway, I'm on top of the care/feeding requirements and such, but one thing remains on my to-do list: escape-proofing. I've heard of fluon, but I won't be able to get that for a while, and I've heard from several keepers in Australia that Vaseline presents a good film to prevent roaches from climbing. Can anybody A: testify to that fact, and B: tell me how often a layer of Vaseline would have to be reapplied? Thanks in advance.
