The crickets seem unable to climb the plastic to even reach the holes. The head and body of the tarantula are too wide to go through. If anything I'll duct tape it. Whens the time to move her to a bigger enclosure?
when she's more than half the width of this one is how i do it. Then i upgrade them to one with a width at least twice their dls to give them a molt or 3 to live in before disturbing them with a rehousing again.
