Reply To: How necessary are isopods and springtails?

If it were me I would use both. And definitely do not collect them from your yard, especially the isopods, that are known to be riddled with parasites that can affect your pet’s health. By using both, you ensure that detritus of different kinds in the habitat are consumed by these invertebrates who occupy similar but slightly different niches.
