Even though it’s normal practice to store live mealworms in the refrigerator, this is not recommended for superworms.

A wide number of things may bring about the demise of a superworm. Most die-offs may be traced to a variety of environmental factors, including too much wetness or too much heat. Moisture. 

The temperature should be between 68 and 88 degrees, with 78 degrees Fahrenheit being the best temperature. The humidity level should be lower than fifty percent.

Superworm beetles may survive up to a year with suitable care. After three to four months, they reach their full size and maturity as mealworms. 

If you’re buying insects from a provider, it’s probably preferable to purchase in smaller batches. Long-term storage of full-size worms may reduce their nutritional value.

Too many worms together in a box without proper air might cause moisture or mildew in the substrate. Alternatively, the substrate could be changed, and the worms should be transferred to a container that has improved ventilation. 

Substrates that are too deep or containers with too many worms might lead to overheating. When possible, keep your superworm container away from windows that get direct sunlight, and this is particularly important if the container has a greenhouse effect. 

Excessive heat might cause the worms to become hyperactive and seem to be attempting to get out of the container they are in. Alternatively, they may form a C-shape and flick their fingers back and forth.

If it is too chilly for the worms, they will stop moving and become dormant. They may burrow quite deeply into the ground in an attempt to maintain their body temperature. 

If the worms are sufficiently warmed, they may resuscitate after a few hours. Once a superworm has passed away, its appearance will abruptly change to a dark gray or black hue. Urgently remove dead worms to avoid unpleasant smells and the development of bacteria.
