I am using a bioactive substrate and the animals (RF tort, hermit crabs) love it for exploring(worms, organic soil, plants from seed) but my little tort got blood mites(I did use outdoor leaves, sticks etc.) . Any advice to prevent a recurrence? The soil was too wet because humidity was a struggle and I am adding Pillbugs and a fogger so I can water less. Also, will Pillbugs or worms eat a buried Hermit crab?
