How to spot it
The leek moth is a small nocturnal moth whose larvae bore into the leaves and stalks of leeks, garlic, and onions. They leave elongated, window-like translucent feeding marks and tunnels in the heart, through which rot often enters. Affected heart leaves bend or twist. In warm summers, two generations occur.
Prevention
Cover your beds with a fine mesh protective net starting from the time they emerge to prevent the moths from laying eggs. This is the most effective prevention. Check the heart leaves and generously cut out individually infested shoots before rot sets in. Consistent crop rotation with a multi-year break on allium species and the removal of crop residues will deprive the moth of overwintering sites.
