My Carmona bonsai tree has suddenly gathered these very minute, black and white coloured insects on them. The plant is still growing well but they're multiplying and looking very disturbing...how do I get rid of them. Please help!

Here's a few more pics

I think they're aphids (or greenfly/blackfly as they're sometimes called). Just last night, I washed my a chilli plant's leaves with dilute dish soap and water to get rid of them. Try this and see if it works

Doesn't exactly sound like the safest thing to do.....any more suggestions? I'll try this if there's nothing else available

soap and spiritus (rubbing alcohol) in water. Drench the above-soil part of the tree e.g., with a sprayer.

Then use bio degradable soap?
