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.
