Tomato hornworms are the bane of vegetable growers everywhere. The average tomato farmer probably hates and dreads these pests more than all other pests combined. While picking off the “worms” may seem like an easy fix (and is relatively effective) it can be time-consuming and, depending on your location, increase the risk of spreading a harmful pest to other plants.
Solving Pest Control Problems in your Garden – Whether you are thinking about starting a garden for the first time or you want to do it better, it is good to know what pests may be a problem in your area so you can prepare for them. You can create an organic pesticide for tomato hornworms that will help prevent these destructive pests from ruining your tomatoes.
Tomato hornworms are bright green caterpillars that grow up to 4 inches long. They can be seen munching on your tomato plants, and they may also eat peppers, eggplants, and potatoes. These pests can live for about 3 weeks or so as a caterpillar before turning into moths. A female will lay about 600 eggs in her lifetime; it takes about two weeks for the eggs to hatch into larvae once they’re laid.
As with any pest control method you use around your home or garden, check the labels of these bug sprays carefully to make sure they’re safe for use around kids and pets. If you have questions about how safe an organic spray is, call your county extension service office or state university extension service to ask them directly.
Tomato hornworms are not only destructive because they eat your plants, but their droppings cause problems as well. They can attract other pests and diseases, and their droppings can act as fertilizer for weeds. If left unchecked, tomato plants and other plants are at risk of wilting and dying.
You may find that the young hornworms have hatched and are now feeding on your tomato plants. If they are in large numbers, they can quickly devastate the plant’s foliage. The female hornworm can lay as many as 400 eggs during its lifetime and an egg can hatch within two weeks. Eggs are small, white, and laid in groups of 30-40 on the underside of leaves.
Ideally, you should catch and treat your tomatoes before the worms get to them. If you see just one hornworm in your garden, there are likely many more nearby. These pests can devour an entire tomato plant in a single day. You need to work quickly when you suspect tomato hornworms are present in your garden.
How To Use Homemade Organic Pesticide On Tomato Hornworms
The number one organic pesticide for tomato hornworms is dish soap. It’s easy, cheap, and effective. To use dish soap as a natural insecticide, simply spray the tomato hornworm directly with soapy water. You can find dish soap in most kitchens and it costs very little money to make your own. Dish soaps are safe around people and animals because they are non-toxic and will not contaminate the soil.
To use this homemade organic insecticide on tomato hornworms:
- Spray your hand with plain water first to test whether or not you have sensitive skin (this will prevent you from burning yourself).
- Put some water into a container large enough that you’re able to dunk most of your hand into it comfortably (you can use a small bucket if necessary).
Eco-friendly soaps are non-toxic, and safe for humans, animals, and the environment. They will not contaminate the soil or groundwater. Eco-friendly soaps are also biodegradable, meaning they break down as they decompose into humus (a nutrient-rich organic material that improves soil fertility).
How To Get Rid of Tomato Hornworms Organically
Tomato hornworms are a common problem for tomato plants and can be difficult to get rid of. The best way to keep the tomato hornworm population in check is by making sure you have healthy plants with plenty of flowers and fruit.
This method involves spraying dish soap directly onto the worms, but you should use caution as they are very sensitive to chemicals and will die if exposed to too much soap solution. When spraying dish soap, make sure that you cover the entire worm so it’s thoroughly soaked in the solution. You’ll want to wash away any residue from your plant after removing all of the dead insects as it may cause other pests or diseases if left on there too long.
If this method doesn’t work alone or if an infestation has become particularly large, other methods should be tried such as using Bt corn (Bacillus thuringiensis), which will cause caterpillars feeding on it to stop eating within 48 hours due to its effects on their digestive systems; applying kaolin clay around plants will help prevent pests from damaging them; planting marigolds near vegetable beds attracts beneficial insects that prey upon tomato hornworms while deterring others species such as aphids which might otherwise be attracted by its flowers’ sweet scent.
What Is The Best Insecticide For Hornworms?
Hornworms are the larvae of the sphinx moth. When they’re young, they look like green worms with a large horns on its tail. As they get older, their bodies turn brown and grow to about 1 inch long. Hornworms can be found on many different types of plants, including tomatoes, potatoes, eggplants, and peppers. They feed on leaves and stems until they’re ready to pupate into moths.
To get rid of hornworms in your garden, you can use an insecticide with Bacillus thuringiensis (Bt). It is a naturally occurring bacteria that prevents hornworm larvae from developing into adult moths. You can apply Bt directly to plants or spray it around the base of plants to kill off any other caterpillars that may hatch later in the season. It will not harm any other insects or animals but will kill only caterpillars that eat it.
How Do You Keep Hornworms Away?
Hornworms are the larvae of moths in the genus Manduca. They are common pests on many plants, especially tomatoes. Hornworms are easy to spot because they are large and have a distinctive horn on their tail end. Here’s how to keep hornworms away from your garden:
– Use row covers or floating row covers to protect your plants from pests like hornworms. These coverings will trap insects and keep them from harming your plantings.
– Plant marigolds around your garden as a natural insect repellant that will keep away many pests including hornworms.
– When planting your tomatoes, add wormwood to the soil so that it is incorporated into the root system of your plants which will deter hornworms from eating them.

The tomato hornworm is a common pest of tomatoes, peppers, eggplants, and other plants in the family Solanaceae. The adults are large moths with a distinguishing black-and-white pattern. The larvae are green caterpillars with large diagonal yellow stripes and a black horn at the rear end.
These pests can cause significant damage to your plants by eating leaves, fruit, and stems. They can also carry diseases that affect the plant’s growth and fruit production.
There are several different types of pesticides available to help control tomato hornworms in your garden. Most of these pesticides are designed to be sprayed on the leaves of your plants or directly onto the insects themselves. Some of these products are organic while others contain chemicals that may cause harm if they come into direct contact with your skin or eyes while handling them during application.
