These include Rosemary, Catnip, Tea Tree, Lavender, Pennyroyal, Rue, Marigolds, Peppermint, Garlic, Eucalyptus, Basil, Tansy, and Artemesia. Citrus peelings repel flies, also, as does pine. Read instructions as some have ingredients that might be harmful to pets and humans. Arrange your plants near doorways, windows, and outside areas that you want insect free.
