Hang the jug in the tree using a wide strip of cloth to protect the tree branch. Use up to three traps per tree for large trees. A traditional nonchemical method for controlling codling moth is to trap mature larvae in a trunk band of Tanglefoot, burlap bags, or corrugated cardboard as they climb up the trunk to pupate under loose bark. Trapped caterpillars or pupae must be killed before they can emerge as adult moths that can lay a second generation of eggs. For effective control, use trunk banding in combination with other control methods.
Corrugated cardboard is preferred for trunk banding.
The codling moth caterpillars will crawl up the tree and into the corrugations to pupate. Be sure to crush and kill any pupae remaining on the trunk after you remove the band. To help control the overwintering generation, put new trunk bands up in August and remove and destroy them between November and January. Even in the best situations, banding will only control a small percentage of the codling moths because many pupate elsewhere on the tree or on the ground. Once the caterpillar has gone into the fruit or nut, it is protected from pesticides.
