Answer: Dear Joe,

The product to use to control this small caterpillar is called Success Naturalyte Insect Control. It is a natural insecticide and works by both contact and ingestion. Although it is not a systemic spray, Success moves through the leaf surface via “translaminar movement” making it resistant to UV light and rain, once the spray has dried. It is effective on a wide range of caterpillars.

When spraying ensure that all foliage, including undersides of leaves is sprayed. The caterpillar will stop feeding immediately but may take up to three days to die. Apply the product in the early morning or late evening. You can repeat the spray at 7-14 day intervals until this pest is under control.

I really haven’t heard whether a mixture of molasses & water added to soil will kill the eggs. You may have to do some further research on this topic.
