Those mites that cluster on your spiders arent parasitic, they're Acarus siro- the grain mite.
They cluster and go dormant as a form of phoresy and dont attack animals. they do, however cause great discomfort and can harm millipedes/centipedes/larvae by blocking spiracles. the only way to prevent grain mites is to sterilize substrate and grow your own feeders and freeze food before feeding it to them.
As for these predatory mites, they are mostly used to kill spider mites.
Hypoaspis is used to control fungus gnats, the others are used to control spider-mites.
