Josh's Frogs Milli Mix Calcium Enriched Millipede and Isopod Substrate (10 quart)


Quantity Available: 60

About This Product

Millipedes and Isopods depend on a good quality substrate for shelter and food. Josh's Frogs Milli Mix provides a source of hardwoods, organic compost, leaves, coco fiber, and trace minerals that your inverts need to thrive.

Milli Mix comes in a 10 quart bag that weighs 5 lbs, and contains enough substrate for a 10 gallon tank.

IMPORTANT NOTE: Millipedes require more than just hardwoods in their diets, so this substrate does not provide a complete diet for them.

Their diet can be safely supplemented with foods such as apples, cucumber, zucchini (all peeled!), romaine or spring lettuce, strawberries, and Repashy Bug Burger.

We highly recommend researching your particular species to provide complete nutrition.

Recommended Animals:

  • Isopods

Recommended Plants:

  • Dried Moss
  • Leaf Litter

Care: Place a 2-4" thick layer of Milli Mix in your invertebrate's enclosure. Depending on the species, add the desired amount of reverse osmosis or distilled water. Mist or add water regularly to provide adequate humidity. 

Replace when substrate becomes uniform (resembling garden soil) or eaten substrate (which will appear as small balls) makes up more than half of the substrate.

Not sure if this is the right substrate for your pet? Josh's Frogs also offers Coco Select, Dig It, ABG Mix, Coco Cradle, BioBedding, incubation media, feeder insect beddings, various shredded barks like Aspen, Cypress, Pine, and more!

Amazing millipede substrate

I picked up a bag of this to use in the terrarium I set up for my millipedes. It works great! They're both thriving and I love the mix of wood matter, soil, and leaves present. My isopods seem to enjoy it as well.


Perfect Complete Diet

Great mix of decomposing wood and leaves
