Do Japanese Beetles Buzz?

Japanese beetles are mostly silent creatures and don’t make much noise at all, especially when they are on the ground chewing up your garden.

When they fly, though, Japanese beetles do make a faint buzzing sound to the human ear, just like many other types of insects do.

Japanese beetles rarely fly, however, and when they do it is usually quickly and only for a short distance. So don’t rely on the buzzing sound from their beating wings to alert you to the presence of Japanese beetles.

Rather than sound, it’s much better to look for visual cues that signify a Japanese beetle infestation. Namely, plant leaves that have holes chewed through them, or even the complete skeletonizing of their leaf structure.
