Insect

Pea Moth

A small moth whose caterpillars burrow into pea pods and feed on the developing seeds, often going undetected until the pod is opened at harvest.

Pea Moth

Symptoms to Look For

  • Pea pods with small entry holes when examined closely
  • Caterpillars and frass inside pods at harvest
  • Some peas partially or wholly consumed within an otherwise normal-looking pod

Affected Plants

Pea

Organic Solutions

Timing

Sow peas early (February - March) or late (after June) so flowering occurs outside the peak moth flight period of mid-June through August.

Fine mesh cover

Cover pea rows with fine insect mesh during the flowering period to exclude egg-laying moths.

Prevention

  • Do not grow peas that will be flowering during July - this is when egg-laying peaks in most of the UK and northern Europe
  • Remove crop debris promptly as pupae overwinter in the soil near where pods fell
