These sifting inserts can easily replace the common (and expensive) green sifting trays. By cutting the bottoms of 2-gallon buckets (from either Home Depot or Lowes), you can now have a DEEP sifting tray for your mealworms, substrate, and even pupae!
A variety of options are available, including mesh sizes and whether you want to cut your own bucket or have SCMW do it with our fancy laser!
