Why Use

The main cause of maggot damage in plums, damsons and greengages 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.

When to Use

Male moths fly and mate on warm nights from mid-May to the end of July. Place the trap in the garden in mid-May.

How to Use

  • Unfold the sticky insert, open the sachet and place the monitoring lure in the middle of the sticky trap
  • Put the insert in the trap, sticky side up
  • Hang the trap at head height on the windward side of the tree. The trap will monitor moths for three average size trees up to 12 metres apart
  • Inspect the traps regularly. If more than 12 moths are trapped per week, treat with a suitable insecticide
  • Replace sticky glue insert and monitoring lure after 6 weeks
  • Remove trap in early September and dispose of the sticky insert and monitoring lure
