Japanese Beetles are destructive pests that can cause extensive damage to a wide range of ornamental and edible plants in the lawn and garden. Spectracide Bag-A-Bug Japanese Beetle Trap2 (Disposable Bags) use a unigue bad design that traps the bugs for good. The unique hourglass shape can trap thousands of beetles and prevents them from escaping. When the beetle season is done, you can just drop the disposable bags in the trash, limiting your contact with the beetles. Read and follow all label instructions.
