However, caterpillars can quickly become a problem for verbena plants, as they can damage the leaves and flowers. In this article, we will discuss different methods of getting rid of caterpillars on verbena plants.
Before you start treating your verbena plant for caterpillars, it is important to identify the type of caterpillar that is causing the damage. There are many different species of caterpillars that can infest verbena plants, and each species may require a different treatment method.

There are several natural methods of controlling caterpillars on verbena plants.
One effective method of getting rid of caterpillars on verbena plants is to simply pick them off by hand. This method is best used for small infestations, as it can be time-consuming for larger infestations.

Neem oil is a natural insecticide that can be effective in controlling caterpillars on verbena plants. To use neem oil, mix 1 tablespoon of neem oil with 1 gallon of water and spray the solution onto your verbena plant. Repeat this process every 7-14 days until the caterpillars are gone.
Introducing beneficial insects, such as ladybugs and lacewings, to your garden can also help control caterpillar populations. These insects feed on caterpillars and other pests, helping to keep your verbena plant healthy and free of infestations.
If natural methods of control are not effective in controlling caterpillars on your verbena plant, chemical methods may be necessary. However, it is important to use caution when using chemical insecticides, as they can be harmful to beneficial insects and other wildlife.

To use BT, mix it with water according to the package instructions and spray it onto your verbena plant. Repeat this process every 7-14 days until the caterpillars are gone.
