I Must Garden offers two distinctively scented and equally effective repellents - Mint Scent and Spice Scent. Both deer repellents contain eggs and garlic - substances that by themselves repel deer. However, I Must Garden takes repellency to an even higher level by adding botanical oils from plants that deer won’t eat - plants such as peppermint, lemongrass, cinnamon, and clove. Not only do the botanical oils from these plants make our repellents smell so much better, but these natural oils increase the effectiveness and longevity of the repellents.
