We have 5 old apple trees and one old pear tree, all 10 to 15 feet high. They have always been good croppers and are professionally pruned every 2 years. In recent years, we have developed a huge problem with Codling Moth. We have used the traps each of the past 3 seasons. The first year 50% of the crop were affected. Last year the percentage was much lower, but it was an enormous crop. This year, the apple crop is much smaller, and it looks like a high percentage are affected again. Some pears are always affected. I understand that most garden insect sprays have been banned. I agree with this, but clearly the Pheromone based glue traps are not working. Any suggestions?
