The full-season dual lure contains two attractants, a highly efficient aromatic lure plus a female sex lure. The aromatic floral lure attracts both male and female beetles, while the sex lure emits the scent of the female beetle, attracting males in large numbers. This combination of lures will catch up to 5 times as many Japanese beetles as a floral lure alone. Say hello and goodbye to Japanese beetles and their grubs.
