I think whoever told you that, is trying to ruin your hunting spots.. My uncle has a bad problem with one of his neighbors hanging stands literally ove the fence of his property, and he uses chlorine bleach and chlorine tablets for a pool and puts it around the guys stand, and deer will totally avoid the area, for a good while. Id say as sensitive as a deers nose it it probably burns their noses to smell it very close, so they stay away form it.
