Our small kowhai trees have been very troubled by the presence in HUGE numbers of the kowhai caterpillar. I understand they will not kill the tree but they certainly make it look unsightly. Is there a way to deter/ exterminate these voracious critters? This year I stopped counting at 1000 squashed caterpillars, but this method did take a concerted effort!!!

Yes that is a big effort to kill them all! Try using an organic Neem oil like Oakdale organics. Stocked in all of our stores.
