What Are Tomato Hornworms?
The tomato hornworm is the larvae of the beautiful sphinx moth. They start their life cycle hatching and growing into green caterpillars.
And even though these moths are beautiful, I don’t want their larva on my tomatoes.
If you’ve ever noticed these green “worms” on your tomato plants, this is cause for alarm! They can be quite large (they can double in size in one day), up to several inches in length and can do quite a bit of damage during this phase.
Their coloring is a green body with varying marks colored in white or black. Plus, they have stripes on their body as well. Identifying those markings early will help you plan your next steps in identifying how to rid them from your tomato plants.

Since they are green, it’s very easy to miss them. Sometimes, it’s impossible to find them during the day. You can try and look for droppings, and follow that trail.
But if you can’t find them during the day, it’s best to have a black light in the house. (this one is very popular, with over 6500 great reviews) And as soon as it gets dark, go exploring. The hornworms will glow in the dark. your kids might have fun helping 😉

If you see any signs, caterpillars, cocoons, or droppings, it’s time to take the next step on how to rid your garden of tomato hornworms. The longer you delay, the quicker they will spread.
How To Get Rid Of Tomato Hornworms Naturally
If you see a hornworm with lots of white pods sticking out of it, leave it alone. It means it’s been infested by wasps it will soon die.
1. Remove them by hand
The good thing (and probably the ONLY good thing!) about tomato hornworms is that they don’t bite or sting humans. Therefore, you can easily grab them and remove them by hand to get them off of your plants.
Depending on how many you have, this process could take a while, but in order to save your garden, it is necessary!
What can you do with the worms once you pick them by hand? If you raise chickens, you can feed them to your chickens. Or, add them to your bird feeders. And if you like to fish, they might make good fish bait.
2. Use a DIY natural homemade solution
Keep the chemicals off your tomato plants and opt for a more natural solution instead. Combine liquid dish soap and water and spray the plants and worms until covered. This should kill off the tomato hornworms without causing any type of further damage to your garden plants.
Some also say that covering the outside of the plants with a bit of cayenne pepper can also help to keep the worms from coming back. Just in case the rain comes and washes away the soap/water combination before eliminating them.
3. Spray with BT (Bacillus Thuricide)
Naturally occurring bacteria that attack caterpillars, but leavers beneficial insects alone, sprays made with BT are safe for your tomatoes and safe for the insects we want in our garden.
Keep in mind that tomato hornworms also like other garden vegetables besides just tomato plants! Always monitor your peppers, potatoes and eggplant plants as well to ensure that you don’t lose those crops, too!
The sooner that you catch them and get rid of them, the better the chance that your garden will rebound and produce!
