But if you do give her more space, she will eventually use it. Most of mine are in jars or Kritter Keepers, but one is in a repurposed aquarium. During the last four years, she has gradually webbed every accessible area.
I don't even keep a lid on them. Once they web up, they never leave their enclosure (unless it's a male). I keep several Kuk's in open lidless deli containers along the baseboards of my walls... all natural pest control. Collected as adults 6 years ago and not one has disappeared.
I'm going to try that next time I get some!
