Here in IL I' m 99% sure they can come onto your property at any time to check you out. Although most of the time they will wait by your home or vehicle and check you on the way out. Most wardens hunt in their free time and they know hunters don' t like to be needlessly disturbed. However, if they have reason to suspect you' re baiting where you' re not supposed to or using an illegal weapon they will more than likely try to catch you in the act.
