Here is the official, written rule on baiting from the Wildlife Code, from the Secretary of State's Website -
(G) With the aid of bait (grain or other feed
placed or scattered so as to constitute an
attraction or enticement to deer). Scents and
minerals, including salt, are not regarded as
bait, however, mineral blocks with food additives
are prohibited. An area is considered
baited for ten (10) days following complete
removal of bait. Hunters can be in violation
even if they did not know an area was baited.
It is illegal to place bait in a way that causes
others to be in violation of the baiting rule.
