I have hundreds of these for the last couple of weeks/months in my orchids:
I tried to get rid of them but since they hide in the pot, I can't wipe them out... I think they eat the bark and not the orchids since the orchids are doing well, I just don't like to see tiny bugs going all around (especially when I water the orchids, the bugs seems to flee the pot for a while).
Update (3 months later): I trashed the bark rinsed the orchids and sprayed with insecticide. It was ok until last week where I saw that they were back (in a lower count). Replacing the orchid medium for my all my orchids cost around 100$ I can't do that too often.
Is there a way to add something to the water that would be damaging to the bugs and not the orchids?
