Fair Chase
It is illegal to use bait, salt, snares, dogs or other domesticated animals to take deer. Bait is considered any product that is transported into a hunting area and placed there for animal consumption. Baits can be in the form of salt, mineral blocks, prepared solid or liquid which is intended for the animal to eat. An area is considered to be baited for 10 days after the removal of the bait and any affected soil.

Does this mean that you can bait deer but must stop 10 days before season?
