About moths & butterflies
The cabbage white is one of the moths & butterflies. Moths and butterflies have wings covered in tiny scales and go through complete metamorphosis. The caterpillar stage does all the feeding and damage, while adults sip nectar or, in some species, don't eat at all.
In pantries and closets, the moths you see flying are a signal. The real problem is the larvae feeding in food or fabric nearby.
What to do about it
- Cover brassicas with fine row covers from planting time
- Hand-pick green caterpillars from leaf undersides
- Apply Bt (Bacillus thuringiensis) sprays to young caterpillars
