I lived in the Dominican Republic for a few years where Neem trees
were introduced in one of the waves of miracle trees, and out in the
south-west where I lived, they grew very well and were popular mostly
due to the belief that the mere precence of these trees is an insect
repellent. As far as I can tell, the insecticidal qualities of this
tree are only achieved by some form of processing of either leaves or
seeds. I can only tell you that hanging out under Neem trees never
seemed to discourage the ferocious mosquitos that found me. I
believe the Neem-tree-alone-as-insecticide to be a myth.
