Pests Guide
Moths are small – around 10 mm long.
Moths have diamond shaped patterns on their wings while at rest
Their caterpillars feed on the underside of crop leaves.
Caterpilar colour varies from yellowish green to grey green.
When the larvae hatch from the egg they burrow into the leaf and feed on tissue within.
As they grow they emerge to feed on the lower leaf surface leaving the upper surface intact.
This distinguishes their feeding from that of cabbage white butterfly caterpillars
Attract natural enemies – spiders and parasitic wasps – by planting carrots, parsnips, parsley, or dill, and allowing them to flower.
Plant tomatoes or wormwood (a herb) among brassicas.
These help to repel white butterflies.
Plant cabbages with cauliflowers and broccoli – butterflies will prefer the cabbages.
Companion Planting - Plant Celery near to brassicas to deter white moths
Repel butterflies with garlic spray.
They often cause damage to crops and scouting the crop will allow detection of caterpillars while they are small and allow treatment before damage reaches a high level.
