Hello, Mauly,
My 2 cents.
I would take the plant outside and remove it from the pot.
Wash all the dirt off the roots with a hose , then soak the roots in a 1/2 strength Bleach solution. There may be eggs among the roots and you want to kill them. You don't want anything hiding there.
Then I would hose down the whole plant.
If you want to spray with the insecticidal soap, I'd do it outdoors really well.
The insecticidal soap should be ok indoors, too, but you can get messy with it, without fear, outside.
Myself, I would be ruthless, because I hate the idea of bugs in my house.
But, like Sheryl, I equally dislike the use of strong pesticides inside my home.
Oh, and be sure to bleach the pot it was in before repotting with fresh soil.
The systemic insecticidal granules should be ok mixed in with the soil, as long as you don't have any pets or children who might be digging in that pot.
Then for 3 weeks, I would quarantine the plant, keeping it away from any other houseplants, until you are certain it is bug-free.
Good luck and let us know how it goes.
