1.5oz White springtails
10x Isopods - Porcellio Laevis Orange or Dairy Cow.
 
Springtails and isopods act as a natural clean-up crew in terrariums.
Springtails feed on fungal spores and early mould growth, helping stop outbreaks before they spread. Isopods consume decaying organic matter (and some mould), removing the excess waste and moisture mould relies on.
Together they keep the substrate balanced and significantly reduce visible mould.
