The main cause of maggot damage in plums, damsons and gages is due to caterpillars produced by the plum fruit moth. In winter female moths lay eggs in trees. The eggs hatch out into caterpillars which feed on fruit in early summer. The monitoring trap allows gardeners to assess the infestation problem and treat with a suitable insecticide if necessary.
