Do Mealworms Have to Be Refrigerated

Therefore, proper ventilation is the key factor for keeping mealworms alive—not cold temperatures from a refrigerator. Additionally, if mealworms are kept too cold they can die due to frostbite or other environmental factors that result from extreme low temperatures.

Mealworms do not need to be refrigerated, although they will last longer if stored in a cool and dry place.
