Japanese beetles attacking your ornamentals and leaving big holes in the leaves? Stop beetles by applying Ortho® Beetle B Gon® MAX Beetle Killer! It’s made with a natural active ingredient that is a live, soil-borne organism, and controls a variety of beetles, including Japanese beetles, June beetles and chafers. As beetles eat the foliage, they also ingest the active ingredient, and then die over a period of days. Bonus point: the product does not adversely affect butterflies, bees, and other insects, if used according to instructions.
