Another question….about grubs this time

last year my strawberries were DECIMATED by Japanese Beetles. i know that the white grubs my neighbor dug up are the Japanese Beetle larva. i NEED to get RID of them!! one year i lost my ENTIRE GARDEN to them AND they killed a small ornamental tree in my front yard! we went through LITERALLY 10 traps to get rid of them and now, four years later they were BACK. i want to plant potatoes in the raised bed, which is where the little things are...my raised bed of all places!! does anyone have any suggestions as to what i can use to get rid of these guys BEFORE i plant? i have seen that "Grub-X" around but i dont know if i can, or should use that in my veggie garden... i know there is not much i can do NOW, in the dead of winter, but one can never be too prepared for spring.
