you mean little green beetles that like to eat japanese maple leaves and everything on the rose bushes? they typically leave my figs alone... then again they have japanese maple and roses to play with. usually, we manually collect them and kill each one of them individually. my .45 is too big for their head, so i just step one them. i'm sure if I shot them like i want to, my neighbors will freak out.
look for milky spore. when your yard is treated with it, it will kill the japanese beetle/june bug grubs. but won't touch the adult beetles.
