My worst pests are bower birds, they eat the bananas, paw-paws and strip the ripe chillies from the plants the moment they appear.
In the aquaponic beds I often get caterpillars from various sources so as I cannot use conventional insect sprays as 99% of those are harmfull to the fish and all the so called organic mixes I've tried are worse than useless. I use DiPel and found it to be excellent.
Dont know if its available in the US but it contains Bacillus Thuringiensis var. Kurstaki and is totally harmless to us, pets, fish, bees etc but unfortunately not aphids.
