Have you noticed some holes in your tomato plants’ leaves, fruits, and stems? Have you found some brown droppings on your garden plants? If the answer to these questions is yes, your observations may indicate the presence of tomato hornworms.
In most cases, the effects of the tomato hornworm become evident first before you see it. This is because its green color helps it camouflage with the color of your tomato plants.
It would help if you took immediate action when you spot them to curb the problem from spreading to all your tomato plants.
You can opt for natural ways like picking them by hand when you spot them on the farm, tilling your soil to destroy them before they hatch, or interplanting your tomato plants with other crops that repel or trap the tomato hornworms. It is possible to adapt some biological ways to control them too.
Getting natural predators and beneficial insects like ladybugs, braconid wasps, or green lacewings will be helpful.
These insects will feed on the tomato hornworms hence getting rid of them. Going for organic insecticides to control the worms is another good alternative. They are a safe way to kill the tomato hornworms without poisoning the crops.
We urge you to continue reading this post for further details on the best methods you can adapt to get rid of destructive tomato hornworms.
Natural Ways of Getting Rid of Tomato Hornworms
Nothing beats the safety and convenience of adopting a natural way as a preventive and control measure against pests. For tomato hornworms, here are some proven natural ways of doing away with them:
Hand-picking to get rid of Tomato Hornworms
I shudder at the thought of touching these worms by hand, but this is the most natural way of getting rid of them. I recommend you look through your tomato plants at least twice a day.
It would help if you searched very keenly for the tomato hornworms considering they can hide so well. Once you spot them, pick them up by hand and dispose of them far away to limit their chances of returning to your farm.
Tilling to get rid of Tomato Hornworms
The pupae of tomato hornworms have the characteristic of hiding underneath the soil before hatching into an adult. I recommend that you dig through your soil. This will help destroy the pupae before they can hatch and begin their destructive activities.
Interplanting to get rid of Tomato Hornworms
Interplanting your tomato crops with beneficial companions is a good solution if you wish to eliminate tomato hornworms.
Some plants naturally repel tomato hornworms and will prevent them from laying their eggs on tomato plants. Some great crops you can interplant with your tomato plants are basil, wildflowers, dill, chamomile, borage, nasturtiums, etc.
Planting trap crops to get rid of Tomato Hornworms
Planting trap crops at a safe distance is a great choice. These trap crops will attract pests away from the garden. A great option would be the flower tobacco plants. It’s been proven that tomato hornworms cannot resist it. They, therefore, will be attracted to the flower tobacco plants and leave your tomato plants to thrive.
Crop rotation to get rid of Tomato Hornworms
Changing the location of your tomato plants will help shift them away from a location infested with tomato hornworms. Ensure they are far enough to prevent the worms from crawling back to the crop.
Biological Ways of Getting Rid of Tomato Hornworms
Certain insects and plants are beneficial in this process when it comes to preventing and controlling tomato hornworms. They include:
Marigolds to getting rid of Tomato Hornworms
Planting marigolds around tomatoes is a good strategy. Tomato hornworms dislike the smell of marigolds. They will therefore be driven away by this. It is essential to note that the best types of marigolds guaranteed to yield are the pot marigold and the tagetes marigold.
Ladybugs to getting rid of Tomato Hornworms
These insects feed on the larva of the hornworm eggs that are found on the plant. They’ll get rid of the tomato hornworms by eating many of the hornworm larvae.
It is estimated that they can eat up to 50 larvae a day. They can be purchased online to help stop tomato hornworms in their tracks before they begin the destruction.
It is recommended that they be released at night to limit their chances of flying away.
Green Lacewings to getting rid of Tomato Hornworms
These insects also work the same way ladybugs do. They will feed heavily on the larva of the hornworm. It is estimated that green lacewings can feed on over 200 garden pests or eggs in one week. If you intend to get them, you can purchase the lacewing eggs.
Parasitic Wasps to getting rid of Tomato Hornworms
Some wasps do a fantastic job when it comes to controlling the tomato hornworm. The braconid wasp and Trichogramma wasp are excellent examples.
These parasitic wasps will sting the tomato hornworm and lay eggs inside its body. The wasp eggs will hatch under the hornworm’s skin and feed on it from the inside. They will eventually kill it and emerge outside to begin the cycle afresh.
And the good news is that they’ll keep increasing in number, and the helpful insects will continue to get rid of the tomato hornworms in your garden.
Organic Insecticides to getting rid of Tomato Hornworms
Organic insecticides prepared using natural ingredients are a safe choice for removing tomato hornworms on your farm. In cases where the area in your garden is too large, the hornworm population is huge, and other natural or biological methods are not working, I will advise you to resort to this. Let me expound on the options available:
Botanical Bt (Bacillus Thuringiensis) to get rid of Tomato Hornworms
This is a safe organic insecticide, considering it will not harm other plants or animals within the area. It will act as a stomach poison against some larval insects, with tomato hornworms being one of those insects.

Also, ensure you reapply for this insecticide after rain because the chances of being washed away during the downpour are high.

You can make this organic insecticide as a DIY at home. To make a soap spray, mix a little liquid soap with water. You can then pour this mixture into a spray bottle and spray it on the infected parts of your tomato plants in the evening or early in the morning. This is an effective way of controlling tomato hornworms.
Neem Oil Spray to get rid of Tomato Hornworms
The oil derived from the seeds of the neem tree has been proven to be a powerful natural insecticide. It can interfere with the life cycle of tomato hornworms during the different stages, such as the egg, larvae, or adult. It can also act as an antifeedant, stopping insects from feeding on leaves and other plant parts.
You can easily find neem oil in stores and food markets. Follow the instructions on the bottle to understand how to mix things up and create an insecticide.
Garden Dust Insecticide by Safer Brand to get rid of Tomato Hornworms
This safe insecticide has been approved by the Organic Material Review Institute (OMRI). Once you spray it on your tomato plants, the tomato hornworms will ingest it and stop eating after several hours.
Within a few days, they will die, and we will have succeeded in getting rid of them. The good thing about this insecticide is that it is safe for other beneficial insects.
The Monterey Garden Insect Spray to getting rid of Tomato Hornworms
This is my favorite insecticide because it is made through the fermentation of a naturally occurring soil bacterium.
What’s more, it has also been approved by OMRI. It is an easy-to-mix concentrate that has the ability to control worms and caterpillars that have the intention of destroying fruits and vegetables.
This is your go-to solution if you intend to eliminate tomato hornworms.
Sevin Insect Killer to getting rid of Tomato Hornworms
This is another effective, non-systemic solution. This implies that it does not penetrate plant or vegetable tissues. Instead, it remains on the surface and kills the tomato hornworms that come to contact with it. To get to know the recommended intervals for application, read through the instructions on the label.
