Japanese Beetles damage plants as both adults and larvae. Adults feed on soft leaf tissue, leaving skeletonized foliage. Larvae feed on roots, especially turf grass, leaving dead, brown patches in the lawn. Cech out this blog entry for tips and products to address both the larvae and the adult bugs.
