Plant quarantine

I found some tiny ant / aphids look-alike insects crawling about on my pot of C. griffithii 'Bintan' today and therefore, I decided to take some actions before things get out of hand.



Maybe submerging the entire pot with the plant under water will do the trick and hopefully kill the insects. And maybe I should implement this quarantine method for each of my future new entry, or at least soak the plant for half a day before planting.
