For years I've kept a few drawers' worth of mealworms for my lizard and chickens. I got the original version of the pupae sifting pan from Mealworm Farming Solutions, and it was a tremendous help in separating pupae and beetles from the worms. Sorting worms is not fun for me, since it means spending a couple hours bent over in the Florida heat, suffering in a face mask because I'm very allergic to the worm frass. I decided to invest in Mealworm Farming Solution's new worm sifting pans to make the sorting process quicker and easier on myself.

They came carefully packaged, beautifully manufactured, no sharp edges, with sizes etched onto the side for easy reference. The pans are pretty high capacity, but since my drawers are on the larger side, I found it easier to do a "first pass" sift without the frass pan and then sift the bedding through the frass pan separately. With the worm pans stacked, I shake the bucket from side to side for a minute, and then let the worms self-sort for a few more minutes. Then, just empty each pan into its own drawer (gently brushing off any clingy worms). SO much easier than hand-sifting through several small wire-mesh pans. My spine and sinuses thank you!!

Another interesting note: I have changed nothing about my mealworm-keeping besides using these pans, but my mealworm population has EXPLODED. I've never seen so many pupae in my life! I have a whole drawer that's just full of pupae now -- I may need to get another rack at this rate. I don't really know why this is happening. Maybe the worms grow and pupate more successfully when they're not competing with bigger worms? Maybe I'm sorting more often because it's easier? Who knows! But I think I'll finally have a big enough colony to sell worms, and thus turn my free-critter-food hobby into an actual income source for us... which is very exciting!

I would recommend these pans to anyone who wants to get serious about mealworm breeding. Thanks so much for the game-changing product, MFS!

*NEW!* LIGHTNING SIFTER™ Pupae Sifting Pan (D-11)

Great design and works as intended!

I decided to buy this metal sifter plate as it wasn't much more than the cost + shipping of a similar product made with much less durable materials. Seems well-designed and arrived thoughtfully packaged; no sharp edges, missing parts or any other quality issues. Safe to say this sifter plate will serve me for years to come!

The sifter plate fits perfectly in my store-branded 5 gallon buckets, with no gaps around the edges even if I put it in a bit crooked, and the U-bolts make it very easy to remove. The few pupae that fall through the grate are either small or freshly molted. I don't mind hand-picking these pupae, but if your goal is to breed bigger worms, leaving the small pupae behind probably helps with that goal. The sifter tends to catch any beetles in the batch too, which is helpful.

I appreciate Mealworm Farming Solution's care and attention to detail, and look forward to seeing what they come up with in the future. (Additional plates for sorting worms by size maybe? Fingers crossed!)

This round pupae sieve is a "must have" for any mealworm farmer!

Their pupae sieve works better than anything I've tried before. It isn't flimsy like the plastic and wooden ones out there. Those break after a few weeks, but this one is sturdy and will last me a long time!

WOW! Using the Mealworm Farming Solutions round pupae sieve made separating my pupae SO easy!!
