Chemical spray or more expensive nematode or biological insecticide solutions are available to treat caterpillars directly.  Spray treatment needs to be thorough and get right inside the plant, past the protective web left by the caterpillars. Therefore we use pump sprays with a lance that get right into the plant, ensuring that all the foliage is covered.  For that reason using a hand spray is not effective. Because we need to kill off any infestation first, treatment is repeated every 7-10 days to start,  and then approximately every 4-6 weeks between March and October. Importantly, the spray is absorbed into the plant, where it kills the caterpillars as they eat the leaves.
