Feverfew is a beautiful flowering plant that is commonly grown for its medicinal properties. However, like most plants, feverfew can be susceptible to caterpillar infestation. Caterpillars can cause significant damage to the leaves and flowers of feverfew, which can ultimately affect the plant’s health and beauty.

If you’re dealing with caterpillars on your feverfew plant, don’t worry! There are several ways to get rid of them and protect your plant from further damage. In this article, we’ll share some tips and tricks for getting rid of caterpillars on feverfew plants.

Identifying Caterpillars on Feverfew

Before we dive into the methods for getting rid of caterpillars on feverfew, it’s essential to identify the type of caterpillar you’re dealing with. Some caterpillars are harmless and won’t cause much damage to your plant, while others can be destructive and require immediate attention.

One way to identify the type of caterpillar you have is by looking at its physical characteristics. Some caterpillars have distinct patterns or colors that can help you identify them. Others may have hair or spines that can cause irritation if touched.

Another way to identify caterpillars is by their behavior. Some caterpillars are active during the day, while others are nocturnal. Some will eat only specific parts of the plant, while others will devour everything in their path.

Natural Methods for Getting Rid of Caterpillars on Feverfew

If you’re looking for a natural way to get rid of caterpillars on your feverfew plant, here are some methods to consider:

Handpicking

One of the easiest ways to control a small infestation of caterpillars is by handpicking them off the leaves and stems of your feverfew plant. While this method may not be practical for a large infestation, it can be an effective way to control the problem early on.

To handpick caterpillars, simply inspect your plant regularly and remove any visible caterpillars by hand. Be sure to wear gloves to protect your hands from spines or hairs on the caterpillar’s body.

Companion Planting

Companion planting is another natural method for controlling caterpillars on feverfew plants. By planting certain herbs or flowers near your feverfew, you can repel or attract beneficial insects that will help control the caterpillar population.

Some plants that are known to repel caterpillars include:

  • Mint
  • Rosemary
  • Sage
  • Thyme

Some plants that are known to attract beneficial insects include:

  • Dill
  • Fennel
  • Marigold
  • Nasturtium

Homemade Insecticidal Soap

If handpicking or companion planting isn’t enough to control the caterpillar population, you may want to try a homemade insecticidal soap. Insecticidal soap is a natural and effective way to control many types of pests, including caterpillars.

To make your own insecticidal soap, mix one tablespoon of dish soap (without bleach) with one quart of water. Pour the solution into a spray bottle and apply it directly to the leaves and stems of your feverfew plant. Be sure to cover all parts of the plant, including the undersides of leaves.

Chemical Methods for Getting Rid of Caterpillars on Feverfew

If natural methods aren’t working or if you’re dealing with a severe infestation, you may need to resort to chemical methods for getting rid of caterpillars on your feverfew plants. Here are some chemical options to consider:

Bacillus Thuringiensis (BT)

Bacillus thuringiensis (BT) is a naturally occurring bacteria that targets and kills many types of caterpillars. It’s available in a powder or liquid form and can be applied directly to your feverfew plant.

To use BT, mix the recommended amount of powder or liquid with water and apply it to your plant using a spray bottle or garden sprayer. Be sure to follow the manufacturer’s instructions carefully.

Systemic Insecticides

Systemic insecticides are another chemical option for controlling caterpillars on your feverfew plant. These types of insecticides are absorbed by the plant’s roots and transported throughout the entire plant, including the leaves and stems.

To use systemic insecticides, mix the recommended amount with water and pour it around the base of your feverfew plant. The insecticide will be absorbed by the roots and transported throughout the plant.
