Mystery Bugs in Phals, HELP!

[orchidgirl82]

Hi Everyone,
I'm new to the board and I am hoping you all can help me.
I have 12 phals in my NYC apt. They are indoor plants and have been doing well, I'm not sure what happened, but somehow they all have weird bugs in them. They are all repotted in fresh mix and some are as old as 3 years so I am really confused how this happened...

I have confirmed that I have fungus gnats in many of them and i read about the trick to use a potato to see if you have larvae in the plants (the whole thing really grosses me out but we all love our chids so we do it, right...), which brings me to my question...

I cut the potatoes in half to test if my other orchids had larvae in them, instead of the larvae coming to the potato, i got a whole bunch of these TINY little brown spots that are moving around on it. I have no idea what they are and if they are bad for the plant. I never would have even been able to see them without the potato since they are SO SMALL. I would take a pic but they are so tiny that it wouldn't show. They are the size of the period on the screen.

Has anyone seen anything like this before and should i be concerned??? It really grosses me out that they are all these bugs living in my orchids. I tried watering them with a dish soap mixture but as soon as i did the fungus gnats got worse so i'm letting them dry out...


Can anyone help??
Thank you!
