Mealybugs :( need repotting advice for multiple species of orchid :(

[Leafmite]

I use isopropyl alcohol on my citrus and indoor strawberry plants and it is pretty effective if done weekly and on the entire plant...and any neighbors. Phals seem to provide safe hiding places for mealies which is why I only have two of them and I keep them far from the citrus. I do not use any pesticides indoors.
Even with the alcohol, I have to be careful that the spray does not drift onto my carnivorous plants, towards the parakeet, or into my cherry shrimp tank.
