Codling Moth Trap

If you have wormy Apples or Pears, chances are pretty good that the worm is the larvae of a Codling Moth. They are universal pests and once fruit is inhabited, there is very little that can be done other than salvaging the good portion with a knife.

Malathion is used as a control of this pest, but you may not need that drastic a measure. There are pheromone traps available that trap the males, removing them from the breeding cycle. You can also make an effective trap using common household ingredients and empty milk jugs as follows:

Wash the milk residue out of a 2-quart milk jug by putting several drops of dishwashing liquid and a pint of hot water in the jug and sloshing it violently. Then rinse the jug out and cut large holes in opposite sides, as shown. There has been some success reported by painting the hole areas red or yellow.

The opposite holes allow air currents to carry the attractant through your orchard, hopefully intercepting the Moths before they land on your trees. You may want to use 2 to 4 traps near each tree depending on the size of the tree. Locate them on poles between the trees, at chest level.

Attractant Recipe:
1-cup Apple Cider Vinegar,
1/3-cup Dark Molasses,
1/8-teaspoon Ammonia,
6 drops of Dishwashing Liquid
Add enough water to make 1-1/2 quarts of Attractant.

1/8 cup of this Attractant is placed into the bottom of each trap soon after bud break. They are cleaned and rebaited on a weekly basis.
