What Comes in a SquirmStack Kit?

🌱 What You’ll Need to Get Started

• Mealworms (order online or from a pet store)
• Dry bedding such as wheat bran or oats
• Hydration: thin vegetable slices (carrot or potato) or water crystals/gels
• A warm, dry space (room temperature works great)

How It Works: Step-by-Step

Step 1: Add Your Mealworms

Place your mealworms into the bottom worm tray along with some wheat bran. This will be their food and bedding.

Step 2: Watch for Pupae

As your worms grow, they’ll begin to pupate. Use a spoon or tongs to gently move each pupa into the pupae sanctuary (the center cap in the top beetle bin). Check your worm tray daily for new pupae.

Step 3: From Pupae to Beetles

Pupae will transform into beetles in a few days to about a week. Once they emerge, they’ll climb down into the main beetle bin. When multiple beetles are present, they’ll begin breeding and laying eggs in the wheat bran across the beetle-bin floor. Eggs are very tiny and can’t be seen with the naked eye.

Step 4: Baby Worms in the Nursery

As eggs hatch, baby worms naturally fall through the perforated beetle-bin floor into the nursery (the tray directly below). No need to add wheat bran here — some will fall through along with the tiny worms. You may add small slivers of vegetables, but they typically won’t eat them until they’re bigger.

At first, you won’t see worms. You might notice tiny “flickers” in the bran — that’s the babies moving around. In a couple of weeks, they’ll be large enough to spot, and you’ll notice frass (worm waste) building up as they eat.

Step 5: Move to the Grow-Out Tray

Once your baby worms are large enough that they won’t slip through the sifter holes, sift them from the frass and transfer them
