Understanding Catalpa Worms
Catalpa worms, or catalpa sphinx moth larvae, are the caterpillars of the Catalpa Sphinx Moth (Ceratomia catalpae). These caterpillars are known for their voracious appetite for catalpa leaves, which can sometimes lead to defoliation of the tree. Despite their size and appearance, catalpa worms are not poisonous to humans. However, they can cause allergic reactions in some individuals, particularly if they come into direct contact with the skin.
- Appearance: Catalpa worms are large, green caterpillars with white and black markings. They can grow up to 3 inches long and are often mistaken for other harmful caterpillars.
- Habitat: These caterpillars are found throughout the eastern United States and parts of Canada, where catalpa trees are common.
- Life Cycle: Catalpa worms undergo a complete metamorphosis, starting as eggs, then developing into caterpillars, pupae, and finally emerging as adult moths.

Managing Catalpa Worms in Your Garden
While catalpa worms are not poisonous, they can still be a nuisance in your garden. If you notice a significant infestation, there are several methods you can use to manage these caterpillars and protect your catalpa tree.

- Manual Removal: If the infestation is small, you can manually remove the caterpillars by hand or with a gentle spray of water. This method is effective but can be time-consuming for larger infestations.
- Chemical Control: In severe cases, you may need to use insecticides. However, it’s important to choose a product that is safe for the environment and won’t harm beneficial insects. Always follow the instructions on the label and use the product sparingly.
