You actually want a container that is shallow, not deep.
They sell these at Target:
You want about 20 square inches of surface area per thousand mealworms
You'll want to leave the lid off, and add bran/bedding to only 1.5" deep to allow moisture and heat to escape.
To care for them they need bedding for food (we use wheat bran) at a shallow depth or they will get too moist at the bottom causing bacteria and fungus to grow on their grain. We keep them at 1.5" deep.
You can also use plain oats or whole barley.
They need carrots 3 times a week for a water source. Potatoes tend to mold, and will infect your grain causing your worms to get sick. They do best with sliced carrots 3 times a week minimum, and to be kept warm.
