How Do Adult Tomato Hornworms Choose Their Host Plants?

They are also drawn to bright colors, so planting white or light-colored flowers near tomato plants can attract them to your garden. Female hornworms will lay eggs on the undersides of leaves, which will hatch into tiny caterpillars in a few days.

Do Tomato Hornworms Have Natural Predators?

Yes, tomato hornworms do have natural predators in the garden. These include braconid wasps, green lacewings, and ladybugs. These beneficial insects can help keep hornworm populations under control. Avoid using pesticides that can harm beneficial insects, as they can do more harm than good in the long term.

How Can I Prevent Tomato Hornworms from Getting on My Plants?

Preventing tomato hornworms from getting on your plants is possible by using certain gardening techniques. Crop rotation is one way to reduce the chances of tomato hornworms finding your plants. This involves planting tomatoes in different parts of the garden each year so that any overwintering pests will not find them. Removing weeds and debris from the garden can also help reduce the number of hiding places for tomato hornworms.

What Should I Do If I Find Tomato Hornworms on My Plants?

If you find tomato hornworms on your plants, the first thing you should do is remove them by hand. Wear gloves and pick them off the plants one by one. Alternatively, you can use a forceful spray of water to knock them off the leaves. If you notice that the infestation is too severe, you may need to use an insecticide to control the population. Be sure to follow the instructions on the label carefully to avoid harming beneficial insects and to ensure that the insecticide is effective.
