It would depend upon if they are velvet removal rubs, or rubs of dominance. If, they are rubs of dominance- start rattling. Bucks respond more to rattling during the pre-rut, actual rut, and post rut- rather than the actual Peak Rut. Once they are settled in with a doe they won't hard pay attention to rattling. So my guess would be to go ahead and use rattling and maybe an early season attractant. Good luck
