I have an orchid that (with no new plants having come into the house) has mealybugs. I've owned it for years so no idea where they came from. I've sprayed it once with imidacloprid and they have reappeared a couple of months later.
Do I ditch it? Take it all out of the pot and spray the roots too?
How long would the little swines take to drown if I soaked the root ball for a day..?
