How to beat Codling Moth

Codling Moth can be a problem for apple growers in Australia that appears in spring and gets worse by Christmas as the population builds up.


The best approach is multi-faceted:

In spring (late October) put out some traps to check for the presence of male Codling Moths.

CODLING MOTH TRAP

Dissolve 1 part sugar and 1 part molasses into a jar of water and cover with a 3/16 inch mesh (this will effectively trap the moths but not bees). Check daily.

If you see a few males then treat susceptible trees as follows:

CODLING MOTH TREE TREATMENT

Selectively spray the little clusters of blossom on your trees with a Pyrethrum based spray.

CODLING MOTH COCOON TRAPS

Band the trunk and larger branches of your apple trees by tying on 6 inch wide strips of cardboard (the type with a corrugated layer) in November, late December and February. These will provide attractive sites for the Codling Moth caterpillars to make their cocoons. Just check them for larvae and kill those you find.
