triple stack of pests- normal treatment or something more

[DirtyCoconuts]

so this is really odd- i was gifted this plant and inspected it well when i received it and it was quite clean and no visible pests.

i potted it up and put it with the rest of the onc types and was delighted that it was only a few months until it spiked


spike was progressing well and then i looked at her today and YUCK. i see ants (normal), scale (none of my other plants have any) and these little white things.

I removed it from the lath house and was going to unpot it and do a pesticide soak and then what?

repot, keep it bare root for a few days to do successive soaks?

i have VERY little experience with any orchid pests (thank goodness) so i don't want to over react nor do i want more pests....

thanks in advance (click to the image and then zoom in once to see clearly
