How to Monitor Codling Moth Activity in the Spring
Suzanne Fellows
Codling moths can ruin your apples, pears or walnuts and who wants that? Codling moths will start emerging, (depending on your temperatures) in March or April. A good way to monitor for their activity is to put out a trap with a codling moth lure. The male moths will be attracted to the pheromone in the lure and get trapped in the sticky substance on the inside of the trap. If your populations are low, then the sticky traps may be enough to disrupt the mating process. If the infestation is heavy then you will want to use a combination of monitoring traps and insecticides that are labeled for codling moths. Another solution is to apply a barrier around your developing fruit so the codling moth larva cannot penetrate such as our Maggot Barriers.
