These purposed mealworm sifters are seriously well thought out and constructed heirloom pieces so long as they never meet up with mealworms or superworms and their pupae the likes of the extraterrestrial sandworms on Arrakis or the Alien creature (both distant relatives of the mealworms and their pupae respectively if just going by some similarity in appearances if not by size, time and space). The Pupae tray quickly efficiently separates the pupae and of course the potato and carrot ‘chips' or ‘crisps’. A simple tap on the underside will dislodge any clinging pupae. That’s easier than trying to dislodge any pupae trapped by the plastic rib supports found on the plastic sifting trays that are really designed for panning gold. The Large, Medium and Small trays are great for spreading out the generations for a consistent supply or for sales if that’s your goal. All trays are conveniently 2x labeled for intended function. Dust is kept in check as the trays both fit snugly and securely upon each other and atop a 5 gallon bucket. Easiest to work with two buckets imo, one to store the frass and to receive the trays as you remove each layer from the sifting bucket. When done sifting, simply return the trays to the emptied sifting bucket in reverse order. Each tray comes with it’s own equally thought out sturdy box and then is further safely shipped in another. Not that I think I’ll ever get around to it, but it would be interesting to know if these sifters can separate gold like the plastic panning trays. In any case, these single material sifters -unlike the mixed material plastic with metal screen gold panning trays- are fully recyclable if they aren’t really able in their future life to seperate out the spice melange from the sandworms on Arrakis or to successfully catch an Alien Xenomorph specimen and bring it back to earth (safely). I do believe the Sigourney and Timothée Worm, Pupae & Beetle Farmers Of The Future Universe will join me in agreeing with this endorsement. Happy siftings.

Best product, high quality, worth the price!

D-11 LIGHTNING SIFTER™ Mealworm Frass Sifting Pan (1st Gen)

I Love it's efficiency. I had just purchased all of the other pans from Amazon and they didn't have the large. I wish I had known there was 2nd Gen in the works because I would have waited. 😢

This pan is a “must-have” to add to your collection. It may seem a little pricey, but I promise you, it’s worth it.

Separates all my wriggly friends, from tiny wormies to beetles, with no muss or fuss.

This sifting pan is a marvellous invention! It separates frass from mealworms with much efficiency. Very happy, 5 stars!

Having purchased multiple pans from this company, the only thing I regret is not getting the five pack from the start! It may seem pricey, but once you see how well they work, you end up buying them all anyway – lol. Do yourself a favor, bite the bullet, and get the five pack. You won’t regret it!

Gettin' my mealworm hustle on without the mess - that's a win in my book!

Don’t ask questions, just buy it - you won’t be disappointed. Time is money. This one’s worth the money!

Look, I've tried it all when it comes to sorting mealworms. But this 5-pan set from Mealworm Farming Solutions? It's the bee's knees! Separates every stage, from pinhead-sized babies to full-grown beetles, with zero hassle. The pans themselves feel like they'll last a lifetime, and stacking them on a bucket saves precious space. Huge thumbs up from this happy mealworm breeder!

The small sifter not only works well for separating small mealworms, it also is excellent for sifting beetles when you’re trying to separate them from their eggs and substrate. Brilliant design and engineering.

Forget the frustration of multiple sifters. Mealworm Farming Solutions' five-pan set separates everything you need – from tiny mealworms to larger adults, pupae, and even beetles. The pans are sturdy, stackable, and have clear functions. This is a true time-saving (and sanity-saving!) investment.

Don't let small mealworms and beetles slow you down. This pan's perfect-sized holes ensure only the smallest mealworms pass through, making separation a breeze. And when you’re ready to move beetles from one bin to another, the same pan can be used to keep all of your beetles on top for easy transfer. It's well-made, easy to use, and saves me tons of time.

This little sifter is a godsend. Now I can sort the small mealworms for my birds much faster. Mom's happy, the birds are happy - everyone wins!
