Very small and tiny white fast running bugs on the roots of my orchid

[Vilija]

RosieC,

Thank you very much for your answer. I was reading about all the bugs orchids can get and it looks like my plant has springtails, they are white, very quick and very small. Probably the size of . or , or somewhere in between.

Can I replace medium and re-pot my plant while it is blooming/new spike is growing? I lost two orchids before (one due to fire in my house and another one didn't get enough light in my old flat) so I am very careful with this one as I don't want to loose it.
