Don't spray at all (or use Bugtrol). Best to plant out when the cool weather stops the butterflies laying.

Or cover the plants with bug proof cloth.

Use a spray containing Bt. Look on the ingredients for bacillus thurigensis kursaki. It should be available at good garden centres. It's got no withhold and is approved for organic growers' use. It's germ warfare, a bacterium that activates in the caterpillars' gut and kills it. No effect on humans, our guts don't activate it. It loses potency after a few hours of sun, so best applied late afternoon or morning. Just follow the instructions and store it as advised on the label.
