Symptoms

Big green caterpillars stripping leaves and leaving dark droppings; chewed stems near the top of the plant.

When it shows up

Mid to late summer as the moths lay eggs on the foliage.

Jul Aug

Treatment

Hand-pick them off (easiest at dusk) and drop in soapy water. Bt spray works on a heavy infestation.

Prevention

Till in fall to disturb pupae, plant dill or basil nearby, and let parasitic wasps do their work.
