The bird feeder store showed me a glass dish with vertical sides about 3/4" high. I had an old butter dish that had similar sides and no worms escaped. I tested it for 4 hours. Maybe it's the glass surface, but the meal worms do not seem to be able to climb out.
My store also suggests placing slices of carrot in the dish and in the keeping container in the refrigerator for the worms to feed on.
For anyone leary about the keeping the worms in the "fridge"--I was squeemish at first. But, they really aren't all that icky--they are cleaner than I imagined--and the cold keeps them fairly immobile. I place them in an open bag just to keep a second surface between the worm box and the refrigerator shelf;
I was told that chickadees and robins also like the worms. ~ ~ ~ ~ ~>O
