Looks likes it is a bit late to try to control the pest, since in organic production you need to implement a IPM (Integrated Pest Management). You need to identify the possible pest you could get, based on the season, weather, historical incidence, etc. Then try to keep actively monitoring the pest or insects and the main source from where they are coming into, the use of sticky traps helps you to monitor and suppress (sort of) the entering of the moths, for this case. Also, if you observed adults laying eggs the next step is to use an organic certified insecticide like a BT (Bacillus thuringiensis) to mitigate the presence of the larva (caterpillar) in your crop from an earlier stage, before they get into the fruit.
good luck on your next crop!
