Today I discovered that a plant next to my compot of Paph. vietnamense seedlings had mealy bugs. And sadly the pest has spread to some of the seedlings in the compot. I removed all the bugs and white foam I could find with a cotton swab drenched in rubbing alcohol and a toothpick. Then I sprayed the affected leaves and between the leaves with a spray containing Thiacloprid 0,015% since that’s all I have at home. What else can I do now? Should I repot them right away and rinse them in water? I don’t really want to use more insecticides since I grow on the windowsill and don’t like chemicals inside the house. This is really disheartening, 12 beautiful, vigorous seedlings from my very first flask, and I've been growing them for almost two years. They were doing so well and now this.
