Japanese Beetles

Cliff Sadof, Extension Ornamental Entomology Specialist , Purdue University

Japanese beetle adults are more abundant and earlier this year than they have been for a number of years. Adults feed on the leaves of over 300 species of plants, and on most flowers. Protect flowers and foliage with weekly applications of insecticides like carbaryl (Sevin)or permethrin (Eight). Turf that has had a history of grub damage ought to be protected with soil applications of imidacloprid (Grubex) or halofenazide (Mach 2).

For more information on Japanese Beetles, please refer to specific bulletins on turf (E-61) and (E-75) for more details on biology and control.
