This year I decided to do some spraying for codling moth on my apples trees (backyard grower in Pacific Northwest with just a few trees in my yard). I have been using Permethrin and have done a couple sprays this season. So far, all my apples look to be completely clear of codling moth damage. I know that there can be be a few generations and what I’m wondering is if anyone knows when I should be doing the next round of spraying to target the new eggs that will be hatching. I’ve been doing some research but everything seems to be in degree days and what I’m hoping for is just a general guideline of when to spray (i.e beginning of June, mid July etc.) just to make sure I keep on track.

If you have nearby neighbors with apple or pear trees, the spraying may never end. I had to bag my apples when I was living in W Washington. There were too many nearby host trees to control without constant religious spraying. A coddling moth trap is a good indicator of when to spray.

I completely agree with nil. You may need to spray for a long time and yet you dont want to spray needlessly. Using monitoring traps is the way to go.
Spray to coat the fruit with Surround WP when fruit are size of quarter. I started 2 weeks ago. Repeat as fruit grows and after each rainfall. Also plug in a bug zapper which is death on codling moths and mosquitoes
Have used these two for over 10 years, takes care of the apple fly maggot and codling moth
