Codling Moth Trap
For those who have wormy Apples or Pears, odds are very good the earthworm may be the larvae of the Codling Moth. They're universal unwanted pests and when fruit is lived on, there's hardly any that you can do apart from saving the great portion having a knife.
Malathion can be used like a charge of this pest, but you might not need that drastic a stride. You will find pheromone traps available that trap the males, removing them in the breeding cycle. You could make a highly effective trap using common household ingredients and empty milk jugs the following:
Wash the milk residue from a couple-quart milk jug by putting several drops of dishwashing liquid along with a pint of warm water within the jug and sloshing it strongly. Then rinse the jug out and cut large holes in opposite sides, as proven. There's been some success as stated by painting the opening areas red or yellow.
The alternative holes allow air currents to hold the attractant using your orchard, hopefully intercepting the Moths before they find your trees. You might want to use two to four traps near each tree with respect to the size the tree. See them on rods between your trees, at chest level.
Attractant Recipe:
1-cup Apple Cider Vinegar Treatment,
1/3-cup Dark Molasses,
1/8-teaspoon Ammonia,
6 drops of Dishwashing Liquid
Add enough water to create 1-1/2 quarts of Attractant.
1/8 cup of the Attractant is positioned into the foot of each trap right after bud break. They're cleaned and rebaited every week.
