A water-based blend of four essential oils that can be used as an alternative to chemical fly sprays.  Shake concentrate well before diluting and shake diluted solution before use. Dilute by using a 1 to 4 ratio with water. Add desired amount of concentrate into sprayer or mixing container, then add appropriate amount of water (one quart of concentrate makes five quarts of spray).  Apply diluted solution as a spray or wipe on.
