Tomato hornworms are large caterpillars with a horn-like tail. Their favorite plant is Tomato. Hornworms chew plant leaves and can completely defoliate plants. Additionally, controlling Tomato hornworms helps maintain the overall health of your garden ecosystem. When left uncontrolled, they can decimate these crops, too, leading to significant losses in yield. Furthermore, successfully controlling Tomato hornworms allows you to enjoy a bountiful harvest of delicious Tomatoes.

This spray contains a bacteria called Bacillus thuringiensis, which specifically targets and kills caterpillars like the Tomato hornworm. Using Bt spray is simple.

The bacteria in the spray will be ingested by the hornworms when they feed on the leaves, causing them to stop eating and eventually die.
