OSU has a trapping program for codling moth. It varies each year a bit due to degree days. Here is a quick overview of the life cycle.

You are behind in your spraying as mid-May to early June is the beginning of the adult stage which will lay the eggs into the fruit. The damage peaks late June into July most years. Last week of June is the usual second control spray. Mid-July is the usual last spray. This are approximate due to weather changes.
