A deer’s keen vision can detect UV light. According to “How Game Animals See and Smell,” a book by Kurt von Besser, many camouflage clothes and laundry detergents contain UV brighteners to make the clothing more appealing to our eyes, which deer can detect. Hunters should use detergents free of UV brighteners. Look on the label and use only a basic detergent. You may not look as sharp, but the deer won't mind!
