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 product works amazing, especially when you have baby crested geckos that you’re feeding. No more hand picking the right size mealworms. Throw them in the pan, sift them out, feed your geckos. Easy and simple.

If you want to save a little money, you can get the flat pupa sifter. It works great. But I recommend their new pupa sifting pan – by far the best mealworm sifter on the market. Saves me so much time and effort and makes farming mealies easy and fun.

Separating mealworms is quick and easy now, and the pan feels built to last. Highly recommend for any serious mealworm breeder.

Worth, every penny. Saves me so much time and effort. Makes farming, worms, easy and fun. And when you have as many crested geckos, as I do, you don’t want to be wasting your time shifting worms. 100% five stars! If anyone says, otherwise, they’re not shifting large quantities. It DESTROYS the green plastic gold sifting pans. Built with high-quality stainless steel, I feel like these will last forever. The worms also can’t get stuck underneath like with the green plastic gold sifting pans. Well done! Excellent company with amazing support!!

Mealworm Solutions' frass pan saves time & keeps things clean.

The pans are built tough and stackable, which is clutch for saving space in my tiny apartment. This is a must have for any mealworm enthusiast, newbie or OG. Highly recommend!

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!

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.

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.
