How to Protect Plumeria from Caterpillars and Leaf-Eating Insects
Introduction
Plumeria, with its fragrant blooms and tropical allure, can also be a target for various leaf-eating insects, including caterpillars. While a few nibbled leaves may not pose a significant threat, a severe infestation can weaken the plant and compromise its health. In this guide, we delve into the identification, prevention, and treatment of caterpillars and other leaf-eating insects on your Plumeria plants.
Identification of Leaf-Eating Insects

Signs of Infestation

Preventive Measures
Regular Monitoring
