You should not need the packing tape for the latteralis, they are non climbers. I never use it and have never had an escapee.

To feed... I use paper towel tubes in the tubs as hides for the roaches and then I have 32oz deli cups. I take a tub and knock the inhabitants into the cup and drop a lid on. Then I use forceps to either feed out of the cup or transfer intot he tank.
