What are organic controls for hornworms on tomato plants?

Here are some effective organic methods for controlling hornworms on tomato plants:

Hand-picking: Regularly inspect your tomato plants for hornworms. When you find them, hand-pick and remove them from the plant. Regularly check the plants underneath leaves and within crevices.

Natural Enemies: Encourage natural predators like parasitic wasps, ladybugs, and birds that feed on hornworms.

Neem Oil: Neem oil is a natural pesticide that can be used to control hornworms. Mix neem oil with water according to the package instructions, and spray it on your tomato plants, paying close attention to the undersides of leaves where the hornworms tend to hide.

Bacillus thuringiensis (Bt): Bt is a naturally occurring bacterium that is harmful to hornworms but safe for humans and other animals. It is available as a commercial pesticide, and it can be sprayed on your tomato plants.

Plant Marigolds: Marigolds are known to repel hornworms and other pests, plant marigolds as companion plants around your tomatoes to help deter them.

Diatomaceous Earth: Sprinkle diatomaceous earth around the base of your tomato plants to act as a natural barrier that can discourage hornworms and other crawling insects.

Row Covers: Covering your tomato plants with row covers or netting can help keep hornworms away from your plants. Make sure the covers are secured tightly to prevent the hornworms from getting inside.

Sticky Traps: Use sticky traps to capture adult moths that lay eggs that hatch into hornworms. Hang the traps near your tomato plants.
