Coddling Moth Apples Southeast MI #890619

Asked December 08, 2024, 3:46 PM EST

I had my first year of apples from a few trees in my 20 tree backyard orchard and all of them were full of moth frass. What can I do to prevent them from damaging my apples? I have read pick up summer dropped apples, spray, and traps. I am wondering about specifics, what kind of spray at what time. What kind of traps should I set and when. Thank you Andrew Rochester Hills MI
