Need help sifting NutriGrubs (black soldier fly larvae), mealworms, and superworms from their substrate? This sifter makes a time-consuming, messy process easy! You can also use the large sifter to hold Dubia Diet and Dubia Dew as a feeding bowl for feeder insects! It keeps the food/water contained yet still allows feeders to climb up the side or eat directly through the mesh. Bowl dimensions are approximately 6"x10".
