... or > How to Use Neem Oil Spray as an Organic Insecticide

I second the recommendation of neem oil spray if it's practical to grow/obtain in your area. Just wash the fruits before eating. Otherwise you might consider a spray made from fermented tobacco leaves, and same thing, wash thoroughly before eating.

Free range chickens under the trees could help. Might not help as much as spray but chickens do wonders for insect control.

I find an uncomfortable amount of eye contact keeps them at bay.
