Another option is to use insecticides that contain spinosad or carbaryl, but be sure to read the label and follow the instructions carefully. It’s important to note that chemical control methods should be a last resort after trying other non-chemical control methods, such as pruning and removing infested branches.

Always follow safety protocols when handling chemical solutions, and keep in mind that some pesticides may be harmful to beneficial insects and wildlife.
