Where Do Japanese Beetles Live?

In the United States, Japanese beetles are most prevalent in the Appalachian mountain range and adjacent areas, and along the eastern seaboard. They can be found along the East Coast from as far south as Georgia all the way up to Canada.

Japanese beetles prefer a cool and moist climate, and Florida is generally too hot for them to thrive. They have difficulty colonizing locations with a hot and dry climate.

Japanese beetles can be found in the southern and southwestern states of the continental United States, but they are not as prevalent as they are in the mid-Atlantic states along the coast. Northern California is conducive to Japanese beetle growth because of its cool temperatures and moderate rainfall.

In the Midwest and other northern locations, Japanese beetles spend most of the year inactive and hibernating. They may only be seen by humans for short few months in the summer time when they emerge to mate and feed.

As the name suggests, Japanese beetles are originally from Japan where they thrive in the cool and moist climate. Islands and coastlines in temperate latitudes are ideal for Japanese beetles.
