How to Build an Isopod Enclosure

Isopods have earned their reputation as the ultimate bioactive cleanup crew (along with their fellow springtail friends). These small crustaceans break down waste, uneaten food, and decaying plant matter, helping keep bioactive enclosures clean and balanced. They're low-maintenance, easy to care for, and a great addition to many bioactive setups.

But before your isopods can get to work, they need a home of their own! Building the right enclosure gives them the humidity, hiding spots, and food sources they need to thrive. Here's how to put one together in a few simple steps.

What You'll Need:

• An appropriately sized bin – In our example, we used a six-quart bin, but the right size depends on how many isopods you're keeping and how much room they need to roam.
• ABG mix – A well-draining bioactive substrate that holds moisture without staying waterlogged.
• Sphagnum moss – Helps create a humidity gradient so your isopods can regulate moisture on their own terms.
• Cork bark accents – Flats, rounds, or half rounds all work great and give your isopods plenty of places to hide.
• Leaf litter – Doubles as both a hiding spot and a food source.
• A calcium source – PangeaCal, cuttlebone, or crushed eggshells all support healthy exoskeleton development.
• A spray/mist bottle – For keeping your substrate and moss evenly moist.

Building the Setup

1. Start with a clean, ventilated bin.
   Make sure your container has adequate airflow so your isopods can breathe and moisture doesn't get trapped. We're using a six-quart bin for this build, but size it up depending on your colony.
2. Add a layer of ABG mix to the bottom.
   How deep you go depends on the species you're keeping, since some isopods burrow more than others. Give burrowing species extra depth to work with.
3. Lightly mist the substrate and mix it in.
   Spray until it's evenly moist throughout, (not soggy though). This gives your isopods a stable base humidity to start from.
4. Sprinkle a layer of leaf litter across the surface.
   It gives your isopods extra hiding spots and doubles as a natural food source.
5. Add a handful of sphagnum moss to one side of the enclosure, then mist it damp.
   Keeping the moss on just one side creates a humidity gradient, so your isopods can move toward or away from moisture as they need.
6. Add your cork bark accents across the enclosure.
   Flats, rounds, or half rounds all work. Spreading them throughout (not just piled in one spot) gives your isopods plenty of spaces to hide.
7. Finish with a calcium source.
   PangeaCal, cuttlebone, or crushed eggshells all work well and support healthy exoskeleton development as your isopods grow.

Your Setup is Ready!

And that's it! In just a few simple steps, you've built an isopod setup that's ready for its new residents. With the right humidity gradient, hiding spots, and food sources in place, your isopods will have everything they need to thrive as your enclosure's cleanup crew.
