Waxworms are the larvae of the Greater Wax Moth they are excellent for all species of pan fish and trout. Hold at 65 degrees for 2 to 3 weeks and then refrigerate if you desire. For best long term results transfer each cup to a container with more surface area. One or two cups can be put in a gallon ice cream pail with the lid left off. Remove any dead bait on a weekly basis. Use the original cup to take with you only what you need for the day. If you plan to use them within 4 weeks, refrigeration may do more harm than good. Once you refrigerate waxworms they should be kept refrigerated.
