Do Japanese beetles come back every year?
Japanese beetles have a one-year life cycle. The adults emerge in late spring or early summer and soon begin to mate. The females lay eggs in the soil, and the larvae hatch and feed on the roots of grasses and other plants. The larvae pupate in the soil, and the adults emerge in late summer or early fall. The adults feed on the leaves and flowers of a wide variety of plants and may cause serious damage in gardens and fields. In late fall, the adults move to overwintering sites, such as wooded areas, and emerge the following spring to begin the cycle anew.
When a beetle is squished, the plant oils that are released do not attract more beetles. In fact, the opposite is true – the plant oils act as a repulsive for other beetles.
