The next improvement is an easier way to separate the waxworms form their sawdust bedding.  Introducing the "Waxy Sifter(TM)" to quickly separate the waxworms from the sawdust bedding.  The standard grate is optimized for the waxworm size.  Additional coarser or finer grate sizes can be made available upon request.   These come in Orange Florescent, Green Florescent, or "other" color category which could be gray, blue, red, purple, etc based on availability.  

Note:  Very handy for people who use waxworms to feed their reptile friends.
