How to kill or get rid of “spittle bugs” on my Tipu tree?
I have a Tipu (brizilian rosewood ) tree and the spittle bugs are very annoiing. Please some advise will help.

I don't know what insecticide products are available in South Africa, but look for an active ingredient of acephate or dinotefuran. These are both very fast acting systemics. Be sure to water adequately before and after the soil treatment to facilitate uptake. Examples:
