Some females also do that before they lay their eggs, they go ballistic climb things and dig.
yea my mack snow goes ballistic before she lays, she takes all of the moss out of her humid hide and spreads it though out the tank... its starting to get annoying!
lol yeah they all pretty much do that, if you want to stop her from doing that put a hole in the top of the humid hide/Laying box instead of the side.
