Preventing Caterpillar Damage

Inspect plants regularly for signs of caterpillars and remove them by hand. Plant flowers like marigolds, daisies, and lavender that repel caterpillars. Release beneficial insects like parasitic wasps to control caterpillar populations. Use row covers to protect vulnerable plants from caterpillar infestations. Apply Bacillus thuringiensis (BT) as a natural caterpillar insecticide.
