One of my plant got aphid and some ants are taking advantage of this tending to farm the aphid honey pots.
If not treated it will weaken this plant and worst could cause virus or fungal infection. I had to get rid of it quick.
Isolate the plant from the rest and at first I try to get rid of the ants by using this ants bait that could eliminate the ants. But it don't seems to work, because they are busy harvesting those honey pots and show no interest to my bait.
For a quick action, decide to clip off two of the most affected leaves and discard them to kill majority of the aphids. The remaining leaves are not that bad, but I must do something to stop recurring.
Leaves cut and sprayed with organic pest repellent, if needed I can make do with soap solution. Since I had this spray at hand, just try it out first before proceeding to the next step.
I had to isolate this plant, to ensure those aphid don't fly off or hop off to nearest safe place and will just makes things worst. Luckily the plants are all in individual pots, which makes it easy to do this.
