McShanes nursery has weekly workshops. In this video we learn about various methods of controlling Codling Moth in Apple Trees.

I am glad you mentioned codling moth! Well here lets give her a surprise. Who knows what a codling moth is? They got a terrible worm and love fruit trees and they eat your apples all day long. That's why we get worms in our apples, codling moths.

There little traps, you set and you put inside your garden right when things start to bloom and buds start to push and inside the trap is a little nugget that a bunch of scientists identified to make the males in feral. When they come out and the buds are pushing they find this trap, lick it a couple of times. After that the little guys are not going to see much action and your tree is not going to have fertile codling moths laying eggs in your apples or quince producing worms.
The most effective way to use those codling moth traps is once you see the codling moths start showing up in them. Use the Bacillus thuringiensis (or Bt) it's a naturally occurring bacteria. If you use the BT at that time then you know that the females are around laying their eggs in your trees on the blooms. Those eggs are getting ready to hatch out into little worms and crawl their way into the apples are quince or whatever. If you spray at that point (with BT) then they get killed before they go into your apples. Once they are in your fruit there really isn't much that you can do to them.

Scientist, a couple decades back found that this tiny bacteria when consumed by these worms causes them to blow up and explode so, they don't do very much damage by the time they have consumed this small bacteria in a form of a spray.
Most of the time those female are laying there eggs at the time that its either a flower or just newly set fruit. So, that the advantage of using the traps, you put the traps in your trees before the flowers open and keep checking them a couple times a week. You check those traps as soon as you start seeing moths in those traps then you can use your BT and that gets the worms before you get into the apples or whatever kind of fruit it is. Apple and quince and maybe pears those are the main things that are effected by codling moths. Each species has there own particular thing. Apricots its brown rot. Peach's its curly leaf. So, you need to learn what kinds of things effect the trees that you have.
