Wandering dude plants, also known as Tradescantia zebrina or inch plant, are popular houseplants due to their attractive foliage and ease of care. However, these plants are sometimes plagued by caterpillars, which can damage the leaves and stems of the plant. If you’re dealing with caterpillars on your wandering dude plant, don’t worry – there are several ways to get rid of them.
Before you start treating your wandering dude plant for caterpillars, it’s important to make sure that you’re actually dealing with caterpillar damage. Caterpillars are the larvae of moths and butterflies and can range in size from tiny to several inches long. They have soft, segmented bodies and feed on plant leaves and stems.
Caterpillar damage on wandering dude plants typically appears as ragged holes or notches in the leaves. You may also notice eggs or small green worms on the leaves or stems of the plant. If you’re not sure whether you’re dealing with caterpillar damage, take a closer look at your plant and see if you can spot any of these signs.
If you prefer to avoid using chemical pesticides on your plants, there are several natural methods for getting rid of caterpillars on your wandering dude plant:
Handpicking: One of the simplest ways to get rid of caterpillars is to simply pick them off your plant by hand. This works best if you only have a few caterpillars to deal with. Wear gloves to protect your hands from any spines or hairs on the caterpillars’ bodies.
Neem oil: Neem oil is a natural insecticide that can be effective against caterpillars. Mix a few drops of neem oil with water in a spray bottle and spray your wandering dude plant, making sure to cover the leaves and stems thoroughly. Repeat every few days until the caterpillars are gone.
Diatomaceous earth: Diatomaceous earth is a fine powder made from the fossilized remains of tiny marine organisms. It works by dehydrating insects, including caterpillars. Sprinkle a thin layer of diatomaceous earth onto the soil around your wandering dude plant and on the leaves and stems. Be sure to wear a mask when applying diatomaceous earth, as it can be irritating to your lungs and eyes.
If natural methods aren’t working, or if you have a severe caterpillar infestation, you may need to use chemical pesticides to get rid of them. Here are some options:
Bt (Bacillus thuringiensis): Bt is a natural bacteria that can be effective against caterpillars. It works by producing proteins that are toxic to certain types of caterpillars, but harmless to humans and other animals. Mix Bt powder with water according to the package instructions and spray your wandering dude plant, making sure to cover all of the leaves and stems.
Pyrethrin: Pyrethrin is a natural insecticide derived from chrysanthemum flowers. It can be effective against caterpillars, but can also harm beneficial insects such as bees and butterflies. Use pyrethrin with caution and follow the instructions on the label carefully.
Permethrin: Permethrin is a synthetic insecticide that is effective against many types of pests, including caterpillars. However, it can be harmful to humans and animals if ingested or absorbed through the skin. Use permethrin with caution and follow the instructions on the label carefully.
The best way to deal with caterpillars on your wandering dude plant is to prevent them from infesting in the first place. Here are some tips for preventing caterpillar infestations:
Keep your plant clean: Regularly remove any dead or damaged leaves from your wandering dude plant, as well as any debris or fallen leaves around the base of the plant. This will reduce the likelihood of caterpillars finding a place to hide and lay eggs.
Inspect plants before bringing them home: If you’re buying a new plant for your collection, inspect it carefully for any signs of pests, including caterpillars. Don’t bring home any plants that appear to be infested.
Use companion planting: Some plants, such as marigolds and garlic, are known to repel pests like caterpillars. Consider planting these around your wandering dude plant to help keep caterpillars away.
Q: Are caterpillars harmful to wandering dude plants?

Q: Can I use insecticidal soap on my wandering dude plant?
A: Insecticidal soap can be effective against some types of pests, but may not be effective against caterpillars. If you’re dealing with a severe caterpillar infestation, you may need to use a more targeted pesticide.
Q: Can I use dish soap to get rid of caterpillars?
A: While dish soap can be effective against some types of pests, it may not be effective against caterpillars. Additionally, it can harm your wandering dude plant if used in high concentrations. Stick to natural or chemical pesticides that are designed specifically for dealing with caterpillars.
Q: How can I tell if my wandering dude plant has a caterpillar infestation?
A: Look for ragged holes or notches in the leaves, as well as any small green worms or eggs on the leaves or stems of the plant. If you’re not sure whether you have a caterpillar infestation, take a closer look at your plant and see if you can spot any of these signs.
