The Q&A Archives: Tomato Worms

Question: How can I get rid of tomato worms?

Answer: Tomato hornworms are big and green with white stripes on their sides and a pointy 'horn' on the back. They are the larval stage of a large brown or gray moth with stripes on their wings. The adults have a 4"-5" wingspan and feed at twilight. You can hand pick tomato hornworms or use Bt (sold as Dipel) to control them. There are also tomato fruit worms that attack the fruit, not the leaves of a tomato plant. Fruit worms are related to corn earworms and they are the larvae of a moth, as well. You can control fruit worms with rotenone. Be sure to follow label directions.
