Vampires are not the only ones that don't like garlic. Many insects, and even rabbits and deer, cannot stand garlic and will avoid anything that has come into contact with this pungent bulb. Garlic Barrier Insect Repellent is a repellent rather than a pesticide, which means that it deters insects and animals from eating the plants rather than killing the ones that do. Humans usually cannot detect a change in taste or smell, but insects, rabbits and deer will steer clear. This repellent is safe to use on basically all plants, both indoor and outdoor, and is effective in repelling most pests. It is also non-toxic and does not contain any chemicals, so it is not only versatile but also safe to use.
