Our composting worms are mixture of species (mainly reds and dendras) selected for their composting ability.
Ants are attracted to dry conditions, so this is usually an indicator that your Subpod is too dry.
Avoid grass clippings (as they heat up), glossy printed paper and cardboard (lots of chemicals) Non Biodegradables (of course), Dog and Cat droppings (can carry human pathogens) and raw meat. [more info]
When you add your food scraps and carbon material to the Subpod, you'll need to mix them through using an aerator. This takes a few minutes each time you feed the worms.
You don’t need to chop everything up small for the worms, but it does speed up the process so your food will break down even faster.
