The spice scent deer repellent has a fresh cinnamon-clove smell that gardeners love and provides effective year-round control against deer damage. As with the mint scent repellent, clove and cinnamon oils have insecticidal, as well as repelling properties. Cinnamon oil also has anti-fungal properties. While the botanical oils used in the I Must Garden deer repellents are chosen for maximum effectiveness against deer, it's nice to know there are other benefits.
