About Pea moth
- Adult pea moths are plain grey/ brown in colour with small pale yellow markings on their sides. They are tent-shaped, have a 15mm wingspan and long antennae.
- Females usually lay their eggs on leaves or flowers during May/ June.
- Eggs are small and flat and are usually laid in groups over a period of 2-3 weeks.
- Larvae are small yellow/ white, dark headed caterpillars up to 6mm long, and emerge after about 3 weeks.
- Caterpillars wander the host plant for a day before entering a developing seed pod in which they feed for up to a month.
- Caterpillars emerge from the pods by eating their way out and over-winter in the soil as pupae in silken cocoons.
- Pea moth larvae are most destructive during July/ August time.
- There is usually only one generation per year.
There are currently no chemical controls commercially available for the home garden to control pea moths.
Note: It is important to read manufacturer's instructions for use and the associated safety data information before applying chemical treatments.
- In small outbreaks remove affected Pods by hand and burn.
- Try to sow peas before or after pea moths have become active and are breeding.
- Remove any other plants or weeds nearby that are host plants for pea moths.
Preventing further problems
- Plant peas within netting or under fleece to keep adults out.
- Try using pheromone traps to dispatch of adults.
- Encourage natural predators such as birds with feeders.
