Try the organic way first. BTW the beetles lay eggs and these transform into voracious petal-eating larvae that is more destructive....

Cannot be. Beetles don't lay eggs on plants. They normally lay eggs in the soil. You might like to show some photos.

One is the larvae the other is mature beetle. These are the only 2 I find on my flowers. See the destruction on just one of the spike by the worms. Melted away within 2days.

Yes, recently did use Neem oil. Use one of the lavare to experiment on to see the result. BTW is does Neem oil harm earthworm and plant roots too? My friend said her hoya died when the solution got into the soil.

I have never had problems with neem. Maybe its because I dilute it quite a lot first.
