Both the apple maggot and the coddling moth cause damage to apples, pears and Asian pears. The apple maggot fly lays eggs just under the skin of the apple, then when it hatches it eats through the fruit. The coddling moth lays eggs on the leaves, branches and sometimes the fruit. When it hatches it eats a tunnel through the fruit to get to the seeds.
Members of the Seattle Tree Fruit Society in Washington state has been using Maggot Barriers to protect the fruit for several years. Maggot Barriers are nearly 100% effective against apple maggot and 75% - 80% effective against coddling moth. Maggot Barriers are small nylon "socks" that are slipped over the fruit when they are about the size of a marble. Unlike a plastic bag or paper bag, they allow water, air and sunshine in.
