Instructions on how to take care of superwormsIf you are planning to not refrigerate the mealworms, they will need to be placed into a Sterilite container or cup full of wheat bran. Wheat bran acts as both a substrate and food and helps to keep your mealworms happy and fed. To provide moisture for your mealworms, you can choose between adding carrots and potatoes. Add only enough carrots and potatoes so that the mealworms can eat within one day, as adding too much can cause the uneaten vegetables to become moldy. Once the vegetables are finished by the mealworms (approximately one day) replenish their supply of carrots or potatoes. Never refrigerate superworms! Unlike mealworms, superworms cannot tolerate low temperatures.They will die if they are left in a refrigerator.
