The only time I've had salt attract deer was from Spring to early Summer , and they aren't legal to hunt then . By the time the season rolls in the salt is considered bait here and therefore illegal too . Having a salt or mineral lick benefits the local herd's health to a very small degree , but won't reliably bring them in at the proper time . I've heard of some guys , mostly southern based , who pour a cup of bleach into a foot deep hole and cover it and swear that a week or so later deer go nuts for it . I can't verify it , and my state would probably consider it bait since the animal would be consuming it .
