Hello Al –
Neem works as an anti-feedant and insect growth regulator on a wide range of insects and will most likely work to control Codling Moth. With that said, broad applications of neem oil can get very expensive. I think you would be better served using a horticultural oil and trichogramma wasps early this spring to attack the eggs. Spinosad is a biological product that is SAFE for most beneficial insects, but toxic to bees exposed to treatment for 3 hours following application. Do not apply this pesticide to blooming, pollen-shedding or nectar-producing parts of plants if bees may forage on the plants during this time period.

Thank you!
