Ideal Temperature, Storage and Maintenance
Waxworms can be stored for a couple of weeks if kept at 55° F. This is the ideal temperature for waxworms; however, most refrigerators are a little colder than this. Often, the butter tray on the door of your refrigerator is the best place to find this ideal temperature. It’s better to keep waxworms at room temp with low humidity than it is to store them in a refrigerator that is colder than 40° F in its warmest area. Cupped waxworms should be stored in their cup. They have entered a stage in their life cycle where they no longer consume food. They are living off the fat supplies in their bodies. This means you’ll see them growing smaller the longer you keep them. Always remove any dead (black) wax worms from the container. It’s extremely important that they be stored in low humidity.
