Japanese Beetles

Japanese Beetle

Don’t let their brown halo trace misguide you—Japanese beetles are no angels. They do have wings though, and can chew their way through your trees and landscape quickly. This summer, keep your trees and shrubs healthy with these tips from your local, licensed Davey tree service professional.

How do Japanese beetles affect my trees?

Japanese beetles swarm tree canopies on warm, sunny days when temperatures reach more than 70 degrees. From mid-June through August, Japanese beetles feed on more than 300 plant species, including: rose, crape myrtle, birch, littleleaf linden, crabapple, purpleleaf plum, Japanese and Norway maples, and more.

What are the symptoms of a Japanese beetle infestation?

Monitor your plants for signs of skeletonizing, areas where Japanese beetles vigorously chew and remove patches of leaf tissue between the veins. The damage ultimately leads to sparse tree canopies and premature leaf drop. Talk to your local, licensed Davey Tree service representative to confirm the diagnosis.

Solutions and Treatment

With some extra care, you can help prevent Japanese beetles from causing major damage throughout the summer season. For example, insecticide treatments may protect new growth during peak activity.

To determine the appropriate solution for your trees and landscape, contact your local certified Davey arborist to request a consultation.
