Little White Insects on My Bark Mix...

[Pete]

I grow phals indoors under lights. Many of my plants are in a bark mix, with others in sphag.

Today after watering my phals in the bark medium, I noticed these miniscule white insects (maybe 1mm, don't seem to fly) emerge onto the bark, They seem to just wander around on the moist bark as they don't try to get on the leaves of the orchid. Once the top drys a bit, they disappear (presumably deeper into the mix where it is most). My orchids are growing vigorously and show no signs of ill health.

Does anyone know what these insects are and if they are harmful to the orchid. It does not appear as if they are harmful, but I do not like bugs of any kind on my orchids.


Also, I purchased Organocide and plan to water the bark orchids with this concoction when they are next due watering.
