Q&A - How To Stop
Tomato Hornworm

Question:
Last year a worm or something ate the leaves of my tomato plant.  How can I make sure that doesn’t happen again this year?

Answer:
The tomato or tobacco hornworm is the caterpillar of the sphinx moth. It is one of the largest caterpillars in North America and has a voracious appetite.  Only a couple of caterpillars can defoliate a tomato plant only a couple of days. They can be controlled by using BT (Bacillus thuringiensis). The BT causes the worm to get a stomach ache and die.
