Succulent plants, with their stunning looks and low-maintenance appeal, are often cherished as potted plants by many gardening enthusiasts. Not only that, these juicy little succulents also attract some unwanted guests like Armyworms / Caterpillars, who sneak into the succulent stems, feasting away. When you spot them, your succulent might be in peril. So, how do you shoo away those unwanted guests? Let's dive into the solutions in this article. Take a look:

Where Do Caterpillars on Succulents Come From?

Certainly, caterpillars don't just appear out of thin air. They're usually the larvae of butterflies or moths. Recall if you've seen these fellows around your room or succulents:

They could be Spodoptera frugiperda, Cactoblastis cactorum, looper moth, Pieris rapae, aged butterflies, and moths. They are harmless to succulents, but they lay eggs on the succulent leaves, which hatch into caterpollars that feed on succulents.

Are Caterpillars Harmful to Succulents?

Absolutely! When you find caterpillars in the roots or stems of your succulents, they've already been munching on them. These nibbled wounds, exposed in the complex soil environment, can become infected by fungi like Rhizoctonia, leading to root or stem rot issues in succulents. Additionally, caterpillars deprive succulents of nutrients, which can result in stunted growth.

How to Get Rid of Caterpillars

Tweezer Removal:

When you find caterpillars on your succulents, the quickest way is to tweeze them out, keeping them away from your garden. Dispose of them in the trash or gently relocate them outdoors if you prefer not to harm them.

Use Neem Oil:

Neem oil, a natural plant ingredient, suffocates most pests and is harmless to humans, pets, and plants. Mix neem oil with water and spray it on succulents. After some time, you'll find caterpillar corpses in the pots. Clean up promptly. You may wonder: How to Use Neem Oil on Your Succulents and Cactus.

Systemic Insecticides:

If the above methods fail to solve the caterpillar crisis, local laws permit the use of systemic insecticides. These can help repel caterpillars and protect against pests like mealybugs, spider mites, etc. Check the label before use to prevent overdosing and harming your succulents.
