Micro Mealworm SquirmStack- Mealworm Farm/Colony

Wondering how to start a mealworm farm/colony? It’s so easy to raise your own healthy live mealworm feeders rather than buying from the pet store each week. The Micro SquirmStack is designed specifically for keepers who don’t need hundreds of worms at once — just a steady supply of small, fresh feeders perfectly sized for smaller pets.

4” x 4” x 5” tall

Perfect for bearded dragons that don’t eat large quantities, jumping spiders, tarantulas, mantids, micro geckos, amphibians, and other exotic pets that thrive on tiny, nutritious prey.

Produce mealworms in a variety of sizes so you always have the right feeder stage available for your pets.

☀️ Micro Mealworm Breeding Box – Compact Stackable Habitat System for Efficient Breeding of Beetles, Raising Mealworms & Frass Separation
Automatic sorting, self-sorting

This scaled-down version of the original SquirmStack keeps all the same smart features in a smaller footprint. Efficiently manage every stage of the mealworm lifecycle — from beetle to tiny mealworm — while keeping your setup neat, organized, and low-maintenance.

Self-sorting features allow pupae to be separated and eggs and baby mealworms to drop safely into the nursery layer below. The middle tier acts as a protected nursery for newly hatched worms. They are so tiny you may not see them at first, but you may notice the bran shifting as they grow safely away from hungry beetles.

Once large enough to sift, worms can be moved to the bottom grow-out tray until they reach the ideal feeder size for your pets.

Remember to allow some worms to pupate and become beetles to keep the colony producing continuously — infinite feeders!
