However, these plants are prone to infestation by caterpillars, which can damage the leaves and stems.

Identify the Caterpillars

Before you start any pest control measures, it is important to identify the type of caterpillar that is infesting your fire stick plant.

These caterpillars are usually green or brown in color and have a segmented body with small hairs.

Handpicking

One of the simplest methods of removing caterpillars from your fire stick plant is by handpicking them. Simply wear gloves and pick off any visible caterpillars you find on your plant. Be sure to dispose of them in a sealed container or bag, so they don’t release their eggs back onto the plant.
