Home Remedy for Tomato Worms

Overview

The tomato worm, also known as the tomato horn worm, is actually a caterpillar of a type of moth. It is a significant pest in the garden and can make quick work of tomato plants, eating them down to the stems, if not eliminated early. In most instances, hand picking the worms from the plants can be an effective means of removal. For larger infestations, or for the squeamish, an insecticidal soap can also work against tomato worms. Incorporating a bacteria that attacks the worms is an added biological agent that can improve the possibility of complete eradication.

Step 1

Choose a dishwashing liquid without any anti-bacterial agents that may kill the bacteria, when added. Purchase the Bacillus thuringiensis bacteria at any home improvement center. While this bacteria is harmless to humans, it is lethal to certain insects, tomato worms among them.

Step 2

Add the water to the sprayer. The distilled water is free of any minerals that may cause a soap scum to form. Mix in 2 tsp. dishwashing liquid for each gallon of water. Add a little of the defoamer at a time, stirring until all of the bubbles are gone.

Step 3

Add in the Bacillus thuringiensis bacteria to the mixture. Although the bacteria is harmless to humans, follow the handling and usage instructions on the package carefully. Mix the bacteria in thoroughly.

Step 4

Pump the sprayer and thoroughly soak the affected tomato plants entirely, in the early evening when the sun will not evaporate the liquid or degrade the Bacillus thuringiensis bacteria.

Step 5

Check for tomato worms in 48 hours. If worms are still on the plants, apply again.
