The Rescue Japanese Beetle Trap is scientifically formulated and engineered to have a controlled consistent release rate that attracts and captures adult beetles. Position the trap next to a non-flowering tree or shrub and at least 30 feet from ornamental plants. Japanese and Oriental beetles fly into the trap's large yellow panels and are stunned on impact; then fall into the attached bag where they can't escape and eventually die. All-in-one trap includes bait. Lasts the entire 6-8 week beetle season.
