G'day Folks,

I was just wondering if there are some mites that live in orchid potting mix that aren't considered detrimental to orchid health? I've previously had the red spider mite - I know this coz I checked the little nasty critters out under a microscope - needless to say I used an insecticidal soap to resolve that issue - but I've noticed some larger mites, white-ish in colour, that are visible to the naked eye and in quite abundant numbers. I haven't noticed any detriment to orchid health though or any scars from them having fed on sap... any thoughts? Is it a case of if they're not causing any problems then leave them be or should I remove them?

I think those are detritivores that are mostly harmless. Not sure though.

I do also have those in my seedlings thumb pots and those seedlings never been infected with spider mites (touch wood). :pray:

Therefore I sometime wonder if they predate on spidermites ??? :think:

Tough to say, but could be either predatory mites or fungus mites (detritivores). There a neat video of fungus mites out there somewhere. I figure they aren't a harm either way, as I have/had them in the past on lots of moss bound plants.
